Page 9: Functional Description
F u n c t i o n a l d e s c r i p t i o n The GUTH modulating valve VSR with multi-spring diaphragm actuator has a travel (stroke) of 20, 30 or 60 mm as standard for the nominal diameters DN 10 to DN 150. The linear movement of the valve spindle is induced by means of an actuator shaft connected by a coupling piece. -
Page 10: Installation Of The Modulating Valve
I n s t a l l a t i o n s p a c e The type VSR valve has a very compact design, so it can be installed practically anywhere in a plant. However, to prevent problems arising in connection with thermal, mechanical or vibrational issues, direct contact with other elements should be avoided. -
