Note:

The 1/4" NPT poppet check valve allows uni-directional flow and prevents backflow in oil & gas systems, with standard 6000 PSI rating and corrosion-resistant materials.

Executive Summary

The 1/4" poppet-type check valve is used in oil and gas systems to allow fluid flow in one direction and prevent backflow, protecting pipelines and equipment. Its poppet design provides fast response and reliable sealing under pressure. The 1/4" size is ideal for small-diameter lines, instrumentation, sampling, or control applications. Male × female connections allow secure inline installation and easy integration into existing piping, reducing potential leak points and simplifying system layout.

Detailed Description

The 1/4" poppet type check valve with male × female NPT connections is designed to allow fluid flow in one direction while preventing backflow in oil and gas systems. Its poppet design provides fast response and reliable sealing under pressure, ensuring protection of pipelines, pumps, and other critical equipment from damage caused by reverse flow or pressure fluctuations.

The 1/4" size is ideal for small diameter lines, instrumentation, sampling, or control applications where space is limited and precise flow control is required. Male × female connections allow secure inline installation and integration into existing piping without the need for additional fittings, reducing potential leak points and simplifying system layout.

Factory tested for cracking and reseal performance, the valve has a standard working pressure of 6000 psi, with optional ratings up to 10000 PSI. It offers selectable cracking pressures from 1/3 to 25 psi, making it adaptable to various flow requirements. The valve is available in corrosion resistant materials such as SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, suitable for demanding oil and gas environments. Heat code traceability ensures quality and material verification, and additional testing options including vibration, temperature, and helium testing are available for critical applications.
