Flow Control Valves Series L20/L21

flow control valves are used to ensure a maximal pressure in a compressed air system. When the pressure, that is preset at the valve, is exceeded, the valve opens and exhausts until the preset pressure plus a hysteresis is achieved.

TÜV-certified flow control valves are produced according to customer data and are officially sealed. flow control valves for steam or liquids are manufactured on request.
