Technical and mechanical design
The illustrations below show the basic design of the valves. Constructional
features, such as the shape of plugs, may differ.
Fluids
Steam ( Fluids possible )
Closing against the pressure
Closing with the pressure
For use with all actuators
Use with electro-hydraulic actuators only
The VVF53..K valves use a pressure-compensated plug. This enables the same
type of actuators to be used for the control of volumetric flow at higher differential
pressures.
