Pressure Sealed Check Valves are engineered and manufactured in strict accordance with international standards such as API 602 and ASME B16.34. Designed to minimize flow resistance and pressure drop, these valves are suitable for horizontal installation only.
The seat ring is precision-lapped and screwed in to ensure a tight shutoff and long service life. The valve disc is precisely designed, accurately machined, and guided to enable reliable automatic shutoff at zero pressure. These check valves are compact, emission-compliant, and available in both swing and piston (lift) constructions for various industrial needs.
