Series F-033, F-042

High Pressure Control Valves for Gases

F-033 / F-042 are patented 2-phase control valves for applications with high differential pressures, up to 400 bar and a maximum operating pressure of 400 resp. 700 bar! These unique valves feature a pressure compensation mechanism, maintaining a constant pressure difference of 4 bar across the flow control section. By doing so both the inlet pressure and the outlet pressure may change without having any impact on the Vary-P valve function.
