High-pressure Non-return Valve

A special purpose high-pressure in-line type non-return valve developed by Diamond Engineering consists of a special metal plug to resist erosion, which is precisely lapped and matched with the seat of precipitation-hardened steel to achieve maximum operating life cycles. This valve can be mounted in any position and suitable for hydraulic as well as pneumatic service up to temperature 300 degree Celsius. It is available in sizes from 1/4 to 1" with screwed connection BSP/NPT or with required special connections. Pressure rating is up to 500 bar. The valve is available in MOC AISI 304/316 and carbon steel (graded).
