Detailed Description

The 3/8" poppet type check valve with male × female NPT connections is designed for uni-directional flow control and backflow prevention in oil and gas systems. The poppet mechanism provides fast response to flow changes and a positive seal under pressure, ensuring protection of pipelines, pumps, and equipment from reverse flow or pressure transients.

The 3/8" size is suitable for small to medium diameter lines, instrumentation, sampling, and control applications. Male × female NPT connections allow secure inline installation, reducing potential leak points and enabling integration into existing piping without additional adapters.

The valve has a standard working pressure of 6000 psi, with optional configurations rated up to 10000 psi. Selectable cracking pressures range from 1/3 to 25 psi, allowing precise adjustment for system requirements. Construction materials include corrosion resistant SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, providing durability in harsh 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 ensures material verification, and additional testing including vibration, temperature, and helium is available for critical applications requiring high reliability.
