4 76.126/4 BUS Desription These ontrol valves are distinguished by their great reliability and auray and make an important ontribution towards effiient ontrol. They run very quietly and meet sophistiated requirements, e.g. provide losing funtions with spring, overome differential pressures, ontrol the temperature of the medium and provide a ut-off funtion. The valve spindle is fixed to the drive spindle automatially. The stainless-steel plug regulates either a linear or an equal-perentage throughflow in the ontrol passage. The valve's high level of seal is guaranteed by a stainless-steel ring pressed into both valve seats and by the appropriate valve plug. The stuffing box requires no maintenane. It omprises onially formed PTFE rings and a spring. The spring ensures a permanent tension on the seals, whih guarantees their tightness with regard to the valve spindle. In addition, a supply of grease ensures that the valve spindle is always lubriated. Furthermore, the grease prevents any partiles in the medium from reahing the PTFE seal. Engineering and fitting notes The valves are ombined with the pneumati atuators VP 242, 243 and 244. The atuator is slotted onto the valve and fixed with srews. The pneumati atuator links with the valve spindle automatially when the former is pressurised with ompressed air. The mehanism automatially loses the onnetion to the valve as soon as it has reahed the lower valve seat. Fitting position The ontrol unit an be fitted in any position exept faing downwards. The ingress of ondensate, drops of water et. into the drive should be prevented. If fitted horizontally, and with regard to the valve spindle, the maximum permissible weight on the valve is 25 kg unless the atuator is supported (to be arried out by the lient) or is subjet to fores ating otherwise. Up to 1 C: in any position, but not faing downwards. bove 1 C: t temperatures above 1 C or 180 C, the valve should be fitted in the horizontal position and the orret adaptor for the relevant temperature should be employed. The adaptor an also serve as an extension, allowing the atuator to protrude from the piping insulation. To protet the atuator against heat, the pipes should be insulated. When fitting the drive to the valve, are must be taken not to turn the valve plug on the stainless-steel seat, otherwise the seal may be damaged. When insulating the valve, the insulation should not extend beyond the onneting lamp on the drive. Fitting outdoors If the devies are fitted outdoors, we reommend that additional measures be taken to protet them against the effets of the weather. ppliations with steam The valves an be used for steam appliations up to 0 C with the same p max values. We reommend, however, that the valves be used only for open/lose operations. When used as a ontrol valve, are should be taken to ensure that valve does not funtion largely in the upper third of its stroke range. This results in an extremely high flow speed, whih greatly redues the valve s servieable life. ppliations with water In order to restrain ontaminants in the water (e.g. welding beads, rust partiles et.) and prevent the spindle seal from being damaged, we reommend the employment of olletive filters, e.g. for eah floor or feed pipe. The omposition of the water should be in aordane with VDI 35. If an auxiliary medium is used, please ontat the supplier of the medium in order to larify whether the valve materials are ompatible. Please refer to the materials table below. If glyol is used, we reommend a onentration of between % and 55%. The valves are not suitable for use with drinking water or in zones where there is a risk of explosion. Other notes onerning hydraulis and noises in systems The valves an be used in a low-noise environment. To avoid noises, the pressure differenes pmax listed below should not be exeeded. These are shown as reommended values in the table of pressure lossest. The pressure differenet Tp vt Tis the highest pressure permitted to at on the valve, regardless of the stroke position, so that the risk of avitation and erosion is limited. The fore of the atuator has no influene on these values. Cavitation aelerates wear and auses noise. In order to prevent avitation, partiularly in appliations with steam, the pressure differenet p ri tt should not exeed the valuet T p ri t = (p1 p v ) 0,5 p1 = Upstream pressure before the valve (bar) bsolute pressure was used in these alulations. = Steam pressure ptvt

7 BUS /7 Explanation of terms used p v Maximum permissible pressure differene aross the valve in any stroke position, limited by the noise level and erosion. The valve as a traversed element is defined by this parameter speifially in its hydrauli behaviour. By monitoring avitation, erosion and the noise thus produed, improvements an be ahieved in both life expetany and durability. p max Maximum permissible pressure differene aross the valve at whih the drive an firmly open and lose the valve. Stati pressure and fluidi influenes are taken into aount. This value helps to maintain a smooth stroke ation and the high level of sealing. In doing so, the valve's p v value is never exeeded. p s Maximum permissible pressure differene aross the valve in the event of a malfuntion (e.g. power failure, exess temperature or pressure, burst pipe) at whih the drive an firmly lose the valve and, if neessary, hold the full operating pressure against atmospheri pressure. Sine this is a quik-lose funtions with 'fast' stroke, p s an be larger than p max or, respetively, p v. The resultant fluidi disturbanes are soon overome and play a minor role here. On the three-way valves, the values apply only for the ontrol passage. p stat Line pressure aross the valve. This orresponds largely to the dead pressure when the pump is swithed off, e.g. due to the level of liquid in the installation, an inrease in pressure via the pressure store, steam pressure et.
