The best way to release pressure

KIESELMANN pressure compensation valves are ideal for airing and venting tanks and containers automatically.

You can rely on proven over- and underpressure protection: Our pressure compensation valves are already successfully in use in numerous plants in the beverage and food industries, the pharmaceutical and chemical industries, and also in biotechnology.

The pressure compensation valve has the function of preventing unacceptable pressure overrun of gaseous media in tanks, containers and system segments.

How it works with over- and underpressure:

Overpressure: Generally, the set pressure is greater than the operating pressure. The valve opens against the spring force when the operating pressure has increased to the set pressure. With an increase in pressure analogous to the opening characteristic, the flow rate is constantly dissipated depending on the maximum permissible operating pressure.

Underpressure: The valve opens against the spring force at a pressure difference of 0.05 bar to atmospheric pressure. The flow rate is dependent on the absolute pressure.
