Technical description
C09 4 swing check valves are automatic check valves. They automatically prevent the reverse flow of the medium. The medium can flow in one direction only. These swing check valves are designed and manufactured to ensure maximum service life and reliability. They are mainly suitable for chemicals and petrochemicals, liquids, gases and steam.
MATERIAL SPECIFICATION
Swing 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.
