Application

For gases and liquids with continuous flow, e.g. for air, air-oil mixture and oil in screw compressors.

Function

Open, if the medium is flowing in the direction of the arrow on the valve of flow is reversed.

Valve design

The valve consists of a housing with valve seat, a valve disc, a conical spring,

a spring support ring and a retaining ring. The valve disc is guided by the

valve housing. Type A non-return valves require little space. The valve opens

fully at minimum flow, because the conical spring's force is carefully matched

to the weight of the valve disc.
