Note:

The 3/8" poppet type check valve prevents backflow and protects pumps and pipelines in oil and gas systems with female × female connections.

Executive Summary

The 3/8" poppet type check valve allows fluid to flow in one direction while preventing backflow in oil and gas systems. It is suitable for small to medium diameter lines, instrumentation, and control applications. Female × female NPT connections provide secure inline installation and integration into existing piping.

The valve is rated for a standard working pressure of 6000 psi and is manufactured and tested to ISO 9001 standards. It is made from corrosion-resistant materials and is factory tested for cracking and reseal performance, ensuring reliable operation and material traceability in demanding oil and gas environments.

Detailed Description

The 3/8" poppet type check valve with female × female NPT connections allows fluid to flow in one direction while preventing backflow in oil and gas systems. Its poppet mechanism responds quickly to flow changes and provides a positive seal under pressure, protecting pumps, pipelines, and other equipment from reverse flow and pressure spikes. This size is suitable for small to medium diameter lines, instrumentation, sampling, and control applications where reliable uni-directional flow is required.

The valve has a standard working pressure of 6000 psi, with optional configurations up to 10000 psi. Cracking pressures are selectable from 1/3 to 25 psi to meet system-specific requirements. It is available in corrosion-resistant materials including SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass.

The valve is designed for reliable long-term operation in demanding oil and gas environments. Its construction ensures consistent performance under varying pressures and temperatures, and the robust poppet mechanism minimizes maintenance requirements while maintaining system integrity over time.
