Suttner unloader valve ST-285 AIR pneumatically controlled

The proven ST-285 unloader valve is now available in the AIR version – pneumatically controlled – for high flow rates.

The “pneumatic spring“ allows for precise adjustment of the operating pressure in both low and high pressure ranges. In direct comparison to an unloader valve with a conventional coil spring, the pneumatic spring does not generate an additional switching pressure peak.

A pneumatically controlled unloader valve can be used, for example, in automated cleaning systems or car washes. The pressure can be remotely adjusted via an air-pressure regulator.
