Suttner unloader valve ST-265 AIR pneumatically controlled

The proven ST-265 unloader valve is now available in the AIR version – pneumatically controlled – for a permissible working pressure of up to 350 bar.

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.
