Angle seat valve VZXF

globepneumatically-operatedfor control

The rugged, all-purpose VZXF angle seat valve is ideal for any application requiring open-loop control of media flows—whether gaseous, liquid, or highly viscous. • Sturdy design • Stainless steel and gunmetal process valves with stainless steel, brass, or aluminum actuators • Different actuator sizes and housing materials • Selection of different seat and shaft seals • For liquids, gases, and other easily contaminated media • Easy-to-clean design Angle seat valves are externallycontrolled valves. They are directlyactuated using compressed air supply.In this process, the seat of the processvalve is raised by a pneumaticactuator. In the normal position, thevalve is closed by a spring. When theactuator is supplied with operatingpressure, it raises the control piston aswell as the valve disc – the valveopens. The valve seat is slanted at anangle of approx. 50° in relation to themedia flow. The flow direction isdetermined by the design of the valve.Angle seat valves are used inapplications in which absolute purityof the medium cannot be ensured, inwhich high-viscosity media are to becontrolled or in vapour applications.
