Cast iron swing check valves are manufactured with nominal diameter Dn150 – Dn1000 mm and nominal pressure Pn1,0 – Pn1,6 MPa.

Identification mark according to the pipeline valves manufacturing tables-figures:
19ч21бр, 19ч19р, 19ч24бр etc.

Swing check valves are intended for use as the devices, which prevent working medium flow in pipelines, which transport liquids, gas.

Swing check valves operate automatically. When the medium is passing in the forward direction, the shutter disc (plug) is turning on the eccentric axis, opening the passage, and is going down during the reverse medium flow by its own weight (of the spring or load) and by reverse medium flow influence.

Swing check valves main parts can be manufactured from the cast iron or other materials according to the Customer’s technical task.
