PSG - Check valve for vertical pipes

Technical description

PSG valves are automatic check valves manufactured in two versions:

1. Check valve for vertical pipes, with automatic overflow – designed to protect the pump against the effects of the recoil caused by the transported medium by overflowing it.
2. Check valve for vertical pipes, without overflow – designed to protect the pump against the effects of the recoil caused by the transported medium by stopping it.

These valves are designed and manufactured to ensure maximum service life and reliability. They are suitable for liquids, gases and steam.

MATERIAL SPECIFICATION

Lift Check valves are made from carbon and stainless steel. The material type can be adjusted according to the customer´s request to optimally suit the operating conditions.
