Stainless Steel Male Thread Check Valve
The Stainless Steel Male Thread Check Valve is a spring-loaded poppet check valve designed for self-acting one-way flow control in high-pressure instrumentation and process systems.
With Male NPT connections at both ends, the valve provides a compact inline solution for threaded installations where reverse-flow prevention and reliable pressure handling are required.
Key Features
- 316 stainless steel construction
- Male NPT inlet and outlet connections
- Working pressure up to 6000 psig (414 bar)
- Multiple cracking-pressure options from 1/3 to 25 psig
- Fluorocarbon FKM O-ring with PTFE backing ring
- Compact spring-loaded poppet design
- Self-acting operation with no external actuation required
Connection Sizes
Male NPT connection sizes are available from 1/4" to 1".
Available configurations should be confirmed according to the required connection size, cracking pressure, operating pressure, temperature, and process media.
Cracking Pressure Selection
Cracking pressure is the differential pressure required to begin opening the check valve. Selecting the appropriate cracking pressure is important because different systems may require different opening characteristics.
Cracking-pressure options are available within the 1/3 to 25 psig (0.02 to 1.7 bar) range. The required setting should be specified when requesting a quotation.
Typical Applications
This male thread check valve is suitable for high-pressure instrumentation and process systems requiring reverse-flow prevention, including gas and liquid service, test systems, process lines, and equipment connections.
Actual valve selection should be based on operating pressure, temperature, media compatibility, connection size, and required cracking pressure.
