Multifunction valve (VMF)

Multifunctional valves integrate several functions in one valve. Like directional control, flow control, load- or counterbalance valve, Pipe rupture, pressure relief and pressure control function. We determine the required functions and priorities depending on the application. Multifunctional valves guarantee a higher safety level, better controllability and are very compact.

Benefits

High dynamics
Fast and Safe shutdown.
Soft switching
Optimal controllability
High pressure rating
