2 Steam traps The main purpose of the steam trap is to hold perfectly steam and discharge the condensate quickly and fully. In addition to these essential features, the steam trap must also discharge air and non-condensable gases. All our steam traps completely satisfy these requirements. Our products range include different models having technical characteristics suitable to meet every kind of requirements or applications. In this page the main steam traps are indicated by family sorted by technical and operating characteristics.

Choice of type B. Choice of size Before discussing these steps, it is necessary to make a general comment from the economic point of view. Giving as granted that the condensate must be discharged, it is highly important not to loos live steam in this process. Assuming that today s cost of steam is approximately 0,02 Euro to a kilogram (and this is very conservative), it follows that a trap, sized for 200 kg/h losing 10% of its steam, in a refinery onstream 24 hours/day, costs in one year 146,00 Euro. If this refinery has steam traps incorrectly sized and, therefore, in such conditions, the loss will be ,00 Euro per year! One can easily calculate what happens if the trap has failed in the open position instead of just losing some steam. The choice of the type and size to a steam trap is a matter of great importance.

4 A. Choice of type The main criteria for the selection of the type are (they cannot be listed in order of importance since it varies from application to application): - Resistance to freezing - Installation versatility - Air venting - Resistance to water hammer - Type of discharge (with temperature regulating control valves, the modulating type is preferable) - Heat Exchange efficiency (traps discharging sub cooled condensate do not allow an efficient heat exchange) - Sensitive to back pressure - Reaction to load changes - Pressure variations (types requiring changes of orifices for different pressure are unfit for wide variations) - Dimension and weight B. Choice of size There are 3 parameters to take into account for a correct sizing: 1. Differential pressure 2. Condensate load to be discharged 3. Safety factor 1 Differential pressure The differential pressure is simply the difference between the pressure upstream and downstream of the trap. When a trap discharges at the atmosphere, the downstream pressure is zero (we always refer to relative and not absolute pressure) and the differential pressure is the same of the line. When there is a condensate return system, there is always some pressure inside it due to friction and line lifting. The best way to know the value of downstream pressure (also called backpressure) is to install a pressure gauge just after the trap. If this is not practical, one should calculate the amount of backpressure by formulas of pressure drop in water ducts adding approx. 0,1 bar for each meter of rise. 2 Condensate load This is the second parameter to be introduced into the capacity tables. For draining of steam mains the quantity of condensate is related to the size of the pipe, to the stream pressure, to the efficiency of thermal insulation, to the outside temperature, to the wind force if any and to the temperature of the line (cold start-up or running conditions). In all the other applications traps are used to drains machines utilizing steam as a heating medium. In these cases the quantity of condensate to be removed will be equal to the amount of steam used by the machines to give the desired performance.

5 3 Safety factor For many reasons the steam trap will not be able to handle on field the condensate loads given in the capacity tables. These reasons are: - Type of discharge (intermittent or continuous) - How the condensate reaches the trap - Presence of large quantities of air - Influence of other traps discharging in the same return line Moreover, there may be incorrect assumptions in the condensate load calculation and it is necessary to take into account at a cold start-up the quantity of condensate to be discharged is a lot more than at running conditions. To summarize, the size of the trap is selected entering the capacity tables with the differential pressure and with the condensate load multiplied by the safety factor. A minimum safety factor 1,2 or 1,5 must be always taken into consideration. Higher safety factors (2 or 4) are required for certain applications. Installation Specific suggestions for a correct installation depend on the application and on the type of selected trap. The following are some general comments: - The trap should always be installed below the drain point. - Try to avoid condensate lifting. If this is necessary, install a check valve just after the trap. - Always install Y type strainer upstream, unless the trap has a built in Y type strainer. - Mechanical and thermodynamic traps should be installed as close as possible to the drain point. - Thermostatic traps should be installed at 1 or 2 mt. from drain point. Do not insulate this cooling leg. - It is advisable to install a check valve upstream of an inverted bucket trap to prevent water seal loss. - A sight glass fitted downstream the trap allows a continuous check of the trap operation. - Always install isolating valves upstream and downstream for maintenance purposes.

On start-up, valve is normally open. When steam enters trap, thermal actuator fill vaporizes to a pressure higher than line pressure. This forces valve into seat orifice to prevent any further flow. As condensate collects, it takes heat from thermal actuator, lowering internal pressure. Line pressure will then compress thermal actuator to open valve and discharge condensate. Valve opening automatically adjusts to load conditions from minimum on very light loads to full lift at maximum load. Restricted orifice in N125L (small opening at bottom of valve seat) prevents trap from discharging continuously on light loads.

MODELS NTD 600 Thermodynamic disc trap (without strainer) NTD 600 S NTD600 with integral strainer NTD 600 B NTD600S with blowdown valve APPLICATIONS Steam tracing Drips Heating OPERATION Incoming air and condensate flow through the trap body and into the control chamber. Line pressure raises the disc off the seat allowing complete discharge. When flashing condensate enters the cartridge, flow velocity increases, creating low pressure underneath the disc. Flashing condensate at high velocity strikes the inside wall of the disc chamber and is deflected to the top of the disc causing a pressure buildup. The disc is forced down onto the seat by this pressure imbalance. The trap remains closed as flashed vapour in the control chamber keeps the disc seated. Pressure inside the cap is not lowered until the trapped flash vapour condenses due to body radiation. Condensing steam lowers the pressure above the disc. Disc is then lifted and the cycle repeated.

As condensate enters the trap, the float and lever mechanism is raised, lifting the valve off the seal, discharging the condensate. Condensate will continue to be discharged at the same rate at which it is entering. Any air or non-condensible gas that may accumulate will be continually and efficiently passed by the thermostatic air vent.

When condensate flows into the trap, the float rises, allowing condensate to be discharged. Once air and non-condensibles have been evacuated, hot condensate will cause the thermostatic vent to close. Condensate will continue to be discharged as long as condensation occurs. During normal operation, an increase in the load causes the liquid level in the trap to rise. The float then rises and rolls off the seat ring, allowing more condensate to flow out. The float sinks as the condensate load decreases, moving nearer to the seat ring, decreasing the effective size of the orifice and allowing less condensate to discharge. This provides smooth, continuous operation that reacts instantly to load variation while maintaining a water sea over the seat ring to prevent live steam loss.

MODELS CLASSIC standard capacity, vertical tank BIG BOY super capacity, horizontal tank HORIZONTAL standard capacity, high pressure, horizontal tank LITTLE BOY reduced capacity, vertical tank SKID standard or custom multiplex configuration OPERATION The vent valve is open, the pressure supply valve is closed and the float is positioned in the lower part of the tank as the condensate or other liquid enters the tank through the inlet check valve. As the tank fills with liquid, the float rises to the point where the spring mechanism snaps past the center position. The compressed spring instantly closes the vent valve and opens the pressure supply. This allows pressure into the tank which forces the liquid through the outlet check valve. As the liquid level falls, the float lowers to the point where the spring mechanism snaps past the center position which immediately closes the pressure supply valve and opens the vent valve. The pressure in the tank decreases, allowing liquid to flow through the inlet check valve, repeating the cycle.

In picture 1 the valve is in rest position, no fluid running through it. In picture 2, once the plant is saturated, the pressure of the main line comes to the valve through the pressure tap and the valve connection. It s the moment to adjust the set pressure required for the main line by the regulation screw. In picture 3 the pressure excess valve is working, as the pressure tap of the piping collects a signal higher than the calibration; the valve then opens discharging in the secondary line. When the primary line is back to normal calibration or less, the pressure excess valve closes, waiting for a new rise in pressure.

90 VRV Valvole rompivuoto / Vacuum breaker valves VRV 1 Queste valvole sono state studiate per evitare la formazione di vuoto negli apparecchi ed impianti a vapore di piccolo e medio volume, come scambiatori, batterie ad aria calda, serpentini, tubazioni di distribuzione, ecc. Al primo accenno di formazione di vuoto nell apparecchio a causa della condensazione del vapore, la valvola si apre automaticamente ed immette aria dall ambiente fino a stabilire all interno dell apparecchio la pressione atmosferica; richiude e rimane chiusa con valori di pressione superiori. Può essere applicata sia subito a valle del termoregolatore o delle valvole di alimentazione vapore all utenza, sia fra l utenza e lo scaricatore di condensa (ovvero sulle sommità del corpo dello scaricatore, se di tipo a galleggiante). These valves are designed to prevent vacuum in steam systems and small vessels such as heat exchangers, pipe coils and similar. When steam condensation creates vacuum the valve begins to open allowing air to enter until system pressure reaches atmospheric value; then it closes keeping a higher pressure inside. This valve can be mounted both at downstream side of the temperature control valve and steam feeding valve either between end using or steam trap (i.e. on the top of steam trap body if it is float type) VRV 3 Condizioni operative / Operating conditions Modello / Model VRV 1 VRV 3 Max press. bar Max temp.

The valve closes proportionally at temperature changing when the temperature rises. The temperature regulator consist of a control valve and a thermostat comprising a temperature sensor, a set point adjuster, a capillary tube and a working piston. The temperature regulators operate according to the liquid expansion principle. If the temperature increases at the sensor, this causes a warming and an expansion of the filling liquid at the same time and therefore the valve closes over the working piston. While cooling-off this occurs in the reversed sense. All thermostats are equipped in series with a excess temperature safety device (max. 50 C above adjusted set point).

125 RP01 RE01 Posizionatori pneumatici ed elettropneumatici Pneumatic & electropneumatic positioners Posizionatore applicato su valvola di regolazione Control valve application APPLICAZIONE RP01 e RE01 sono posizionatori a semplice e doppio effetto con segnale in entrata 3 15 PSI o 4 20 ma per il controllo proporzionale di attuatori lineari. Gli apparecchi confrontano il segnale proveniente dall unità regolante con la posizione della leva di feedback collegata all attuatore. La comparazione tra queste due forze genera una pressione di uscita che agisce direttamente sulle camere dell attuatore. APPLICATION The single & double-acting positioners RP01 and RE01 require an input signal of 3 15 PSI or 4 20 Ma for proportional control actuators. The positioner compares the output signal from a controller with the position feedback, and varies a pneumatic output signal to the actuator accordingly. The actuator position is therefore guaranteed for any controller output signal and the effects of varying differential pressure. CARATTERISTICHE FEATURES Eccellente risposta dinamica. Good dynamic response. Costruzione estremamente compatta. Particularly compact design. Regolazione indipendente dello zero e del campo (fig. 1 e Indepentend Zero and Span adjustment (fig. 1 & 2). 2). Predisposizione per funzionamento in Split-Range. Split-Range operation. Insensibile alle variazioni della pressione di alimentazione. Insensitive to pressure variations. Staffa regolabile su tutti gli attuatori IEC 534. IEC 534 standard bracket adjustable. Campo della pressione di posizionamento (alimentazione) regolabile da 0,2..1 a 0,2..10 bar. Adjustable positioning pressure range (air supplì) from 0,2..1 to 0,2..10 bar.

Per regolare la velocità dell attuatore agire sulla vite A (fig. 1). INVERSIONE DELL AZIONE I posizionatori vengono forniti per il funzionamento in azione diretta. Per invertire l azione è sufficiente svitare il tappo dall uscita OUT2 e inserirlo nell uscita OUT1. FUNZIONAMENTO A DOPPIO EFFETTO I posizionatori RP01 e RE01 offrono la possibilità di essere utilizzati sia come posizionatori a semplice effetto, che come posizionatori a doppio effetto. VALVE SPEED ADJUSTMENT With RP01 and RE01 a splitted opening/closing speed adjustment can be made by simply turning a screw. To adjust the actuator speed operate on screw A (fig. 1). REVERSE ACTION The positioners are normally supplied for direct action. In case the reverse action is requie, then remove the plug from OUT2 and put it inside the OUT1.

130 NBB2-12GM50-E2 Sensore induttivo / Inductive sensor APPLICAZIONE In alcuni tipi di applicazioni definite, gli interruttori di prossimità ad elevata distanza di commutazione facilitano la soluzione dei problemi di rilevamento, per es. in caso di spazi limitati, di oggetti di piccole dimensioni ed in caso di fattori di riduzione sfavorevoli. Va detto inoltre che giocano un ruolo molto importante nel caso di scarse possibilità di regolazione, nel caso di tolleranza di un gioco meccanico grande e nell impiego di rivestimenti protettivi. APPLICATION For some applications proximity sensors with increased switching distance can be used to solve detection problems such as small object detection or overcoming the effects of material dependent reduction factors. In addition, these extended range sensors may be used to solve issues such as mounting restrictions, mechanical tolerances or for detection through protective coatings.
