Piston Check Valves
The piston check valves (also known as lift check valves)comprise of a plug which is lifted by upstream pressure and returned onto its seats by gravity/higher downstream pressure to stop the back flow.
We offer OMB/Vogt piston check valves for various industrial applications incl. cryogenics where no slamming is required. OMB standard design are forged acc. to API 602/ ISO 15761 and are supplied with spring making their installation possible in vertical and horizontal directions.
