1 Linear 3-Way Control Valve PN 10/16/25, DN15 - DN300 BENEFITS Nominal pressure PN 16 Almost linear Two balance single seats kvs Regulating capability > 25 kvr Leakage 0.05% of kvs For regulating of process and central heating plants ACHIEVING OPERATIONAL EXCELLENCE We proudly deliver a unique and competitive product, guaranteeing reliable operation and performance. Whenever a media is heated or cooled to a certain temperature, Clorius Controls has the most efficient solution. APPLICATION DESIGN CONTROL OPTIONS Thermostat DN Control valves type G3F are designed for regulating of water, lubricating oil and other liquid media and can be mounted in the pipe system as either mixing or diverting valves. However, when mounting as a diverting valves the pressure drop is increased, compared with mounting as a mixing valve. In case the valves are applied as diverting valves, the pressure drop will increase by 35% and the k vs value will decrease by 14% as against mixing valves. The valves are used in conjunction with our temperature regulators for controlling industrial processes, district and central heating plants and marine installations. The valve components - seat and cone - are made of gun metal, the spindle is made of stainless steel. The valve body is made of nodular cast iron EN- GJS with flanges drilled according to EN or ANSI B16.5 Class 150. The connection thread for the actuator is G1B ISO 228. The valves have two balanced single seats and are designed for tight closure. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Tight between port 1(AB) or 3(B) is optional. 2 (A) 1 (AB) FUNCTION TECHNICAL DATA Electric Actuator 3 point, analogue Pneumatic Actuator spring close/open Without an actuator being connected, connection 2-1 is fully open and connection 3-1 completely closed, by means of a spring. By increasing pressure on the spindle, the opening of the ports changs proportionally to the travel of the spindle, and when the spindle is pressed to the bottom, connection 3-1 is fully open and connection 2-1 completely closed.

2 Electronic Temperature Control Electronic System Electric actuator PLC Programmable Logic Controller The electronic temperature and pressure control system combines an electrically actuated threeway control valve with an electric controller and essential temperature sensor. Microprocessor-based Controller type ER2000 for electronic temperature control is used for constant temperature control. It is suitable for all heating and cooling control systems. The ER2000 is a single loop controller which is intended for marine installations and other industrial applications - such as cooling water and lubricating oil installations, flow temperature control etc. Controller ER 2000 Sensor Microprocessor-based Controller type ER3000 Electronic Temperature Control is used where conventional single loop controllers cannot maintain a constant and precise temperature. Controller ER 3000 Sensor The ER2000 and ER3000 controllers are panel mounted as well as fully programmable, which allows for uncomplicated system configuration. The valve is designed for mixing and diverting media flows. 6 7

3 Pneumatic Temperature Control Pneumatic actuator Type AD/ADHW Pneumatic System PLC Programmable Logic Controller The pneumatic temperature control system integrates a pneumatically actuated threeway control valve with controller and essential temperature sensor. The pneumatic system is especially suitable when there is lack of electricity or when a fail-safe system is required. PPR/EPR PN Controller The electro-pneumatic temperature control system utilizes both electric and pneumatic technology, composed of a pneumatically actuated three-way control valve and electro-pneumatic positioner. Clorius Controls EPR/PPR Electro-pneumatic/pneumaticpneumatic positioner is a rugged control device especially suited for harsh environments and engineered to meet the highest and most demanding control performance that the process industries of today require. The AD/ADHW pneumatic actuators are made according to the Scotch Yoke principle, which is characteristic for its high torque when required - at the beginning and at end of each operation. This increases safety and reduces the energy consumption. The filter regulator, equiped with auto drain is protecting the positioner from dust, water and oil particles in the compressed air supply. With the backflow function it incorporates a mechanism to exhaust the air pressure in the outlet side reliably and quickly. Filter regulator Controller ER 3000 Sensor 8 9

6 Differential Pressure Controls The function of the TD-controls is to reduce the high and fluctuating pump head in district heating systems and other large distribution networks to a suitable and, under all cisrcumstances, a constant differential pressure. Function The TD-controls are primarily for use in water systems where they maintain a constant differential pressure across 2 points and ensure stable flow conditions. With the lower pressure connected to the valve side of the diaphragm and the higher pressure to the other side; the differential pressure across the diaphragm will be balanced by the force exerted by the spring. Any change in the differential pressure will cause the diaphragm and the valve mechanism to move up or down to restore the set condition. Adjustment of the differential pressure setting is made by rotating the setpoint adjuster clockwise or anti-clockwise until the desired set point is reached.

7 Pressure Reducing Valves G1PR / H1PR This unit is designed for maintaining the pressure downstream of the valve to an adjusted set point value. Function The medium flows through the free area between the seat and cone in the direction indicated by the arrow on the body. The position of the valve cone determines the flow rate and consequently the pressure ratio across the valve. The downstream pressure is transmitted through the compensation chamber and the capillary to the diaphragm, where it is converted into a positioning force. This positioning force is adjusting the cone with dependence on the force of the operating springs. The spring force can be adjusted by using the set point adjuster. The valve cone is pressure balanced. The fluid pressure acts onto the bottom and top surfaces of the cone at the same time. In this way, the forces produced by the fluid pressure on the cone, are compensated.

8 Simple Construction Self-acting temperature controllers from Clorius Controls exploit the way in which liquid changes its volume as temperature fluctuates. Activation occures at deviations from the set temperature, where liquid from the sensor part influences the stem of the valve through a capillary tube. Thus there are no operating costs for controlling and activating the valve. Self-acting temperature controllers from Clorius Controls are also available with two sensors, which regulate according to the temperature at two measuring points. Individual Adjustment Calibration The controller is easy to calibrate in case of discrepancies between the set temperature and the actual temperature. Move the scale (2) until the set temperature is the same as the actual temperature. The scale will now be accurate. Adjusting The Temperature Turn the handle (1) until the top of the scale bushing points to the wanted temperature on the scale (2). The temperature seating can be changed at any time, also while the controller is in use. Thermostats Of Stainless Steel Clorius Controls additionally offers thermostats of stainless steel, which are particularly suitable for installation in demanding environments such as outdoor plants and in non-magnetic areas, e.g. in submarines.
