A pressure containment valve ensures that the pressure downstream of the valve remains at a predetermined level. If the pressure tends to drop, the valve opens to add pressure into the system. Otherwise, the valve stays closed.
Pressure containment valves are suitable for steam, liquids, and gases.
For pressure containment, you can choose whether to use valves where the pressure regulation occurs entirely inside the valve as a function between the inflow pressure of the line and the adjustable closing spring of the valve, as in the case of NIEZGODKA and ARI pressure containment valves.
Another approach, allowing slightly more stable pressure containment, is used in models where the pressure is regulated by a membrane actuator. An impulse pipe connects the actuator to the upstream side of the valve. On the other side of the membrane, there is a spring; the pressure setting can be changed by adjustment of its spring force. GESTRA pressure containment valves are based on this technology.
We assist in the selection and sizing of a pressure containment valve that meets the requirements of your application.
