Stainless Steel Opening Pressure 0.3 Psi Check Valve

Stainless Steel 316 Check Valve with 3/4″ Male G straight thread is designed to prevent reverse flow in high-pressure fluid and gas systems. With a maximum working pressure of 430 bar (≈ 6235 PSI) and an ultra-low opening pressure of only 0.3 PSI, this valve ensures efficient flow control while maintaining system safety and performance.

Manufactured from high-quality 316 stainless steel, the valve offers excellent corrosion resistance and long-term durability, making it suitable for demanding industrial environments and aggressive media.

Product Features:

• High Pressure Capability
  Designed to withstand working pressures up to 430 bar, ideal for high-pressure hydraulic and gas applications.

• Low Opening Pressure (0.3 PSI)
  Allows flow to start with minimal pressure loss, improving system efficiency and responsiveness.

• 316 Stainless Steel Construction
  Provides outstanding resistance to corrosion, chemicals, and high temperatures for extended service life.

• Straight Thread Male G Connection
  3/4″ Male G (BSPP) thread ensures reliable sealing and easy installation with compatible fittings.

• Reliable One-Way Flow Protection
  Effectively prevents backflow, protecting pumps, instruments, and sensitive system components.

Typical Applications

This stainless steel check valve is commonly used in:

• High-pressure hydraulic systems

• Gas distribution and control lines

• Chemical and petrochemical processing

• Instrumentation and pressure protection systems

• Industrial fluid handling equipment

The combination of high pressure resistance, low cracking pressure, and robust 316 stainless steel construction makes our check valve an excellent choice for systems requiring reliable backflow prevention with minimal pressure loss. Its straight thread design ensures secure and leak-free installation in standardized piping systems.
