The VUG seriesprovides a wide range of through flanged valves of the PN25/16 pressureclass,with sizes from DN15 to DN150. These regulating valves contain nosiliconegrease and are particularly suitable for the continuous control ofcold, warmor hot water, steam or air in HVAC systems. The VUG series meets therequirements for control units stipulated in DIN 32730. Suitable foruse withthese valves are the AVP242, AVP243 and AVP244 pneumatic actuators. Thevalvecharacteristic is equal-percentage. The valve body is made of ductilecastiron, while the seat, spindle and plug are made of stainless steel(plugs ofsize DN15 to DN50 have a Teflon ring reinforced with fibre glass). Astuffingbox with a spring-loaded Teflon disc guarantees the tightness of theseal atthe spindle. Closure can be either with or against the pressure.
