Pressure containment valves

The task of pressure containment valves is to ensure that the pressure after the valve remains at the predetermined level. If the pressure tends to drop, the valve opens and adds some extra pressure into the system. Otherwise, the valve stays closed.

Pressure containment valves are suitable for steam, liquids and gases.

Two operating principles

For pressure containment, you can choose whether you want to use valves where the pressure regulation occurs as a function between the inflow pressure of the line and the adjustable closing spring of the valve, like in the case of NIEZGODKA pressure containment valves.

The second, a slightly smoother operating mode is used in GESTRA models, in which case the pressure regulation takes place by increasing or decreasing the spring force against the pressure from an adjustment ring via the impulse pipe. The impulse pipe is located on the upstream side of valves.
