KIESELMANNpressure compensation valves are ideal for airing and venting tanks andcontainers automatically.
You canrely on proven over- and underpressure protection: Our pressure compensationvalves are already successfully in use in numerous plants in the beverage andfood industries, the pharmaceutical and chemical industries, and also inbiotechnology.
Thepressure compensation valve has the function of preventing unacceptablepressure overrun of gaseous media in tanks, containers and system segments.
How it works with over- and underpressure:
Overpressure: Generally, the set pressure isgreater than the operating pressure. The valve opens against the spring forcewhen the operating pressure has increased to the set pressure. With an increasein pressure analogous to the opening characteristic, the flow rate isconstantly dissipated depending on the maximum permissible operating pressure.
Underpressure: The valve opens against thespring force at a pressure difference of 0.05 bar to atmospheric pressure. Theflow rate is dependent on the absolute pressure.
