Detailed Description

In oil and gas systems, controlling the direction of fluid flow is critical to protect pipelines, pumps, and equipment. The 1/4" poppet type check valve with female × female NPT connections provides reliable uni-directional flow, preventing backflow and maintaining system integrity. Its compact size makes it ideal for small diameter lines, instrumentation, sampling, and control applications, while the female × female connections allow secure inline installation without additional fittings.

The valve has a standard working pressure of 6000 PSI, with optional configurations rated up to 10000 PSI. Selectable cracking pressures from 1/3 to 25 PSI allow precise adaptation to system requirements. It is available in corrosion-resistant materials including SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, ensuring durability in demanding oil and gas environments.

All valves are factory tested for cracking and reseal performance, with pneumatic testing at 1000 psig to verify seat integrity. Heat code traceability guarantees quality and material verification, and additional testing, including vibration, temperature, and helium, is available for applications requiring maximum reliability.
