Q: What is the maximum working pressure this check valve can handle?

A: The 304 stainless steel one-way check valve is rated for a working pressure of 0 to 3 MPa (approximately 0–435 PSI), making it well-suited for medium-pressure water, pneumatic, and general fluid control applications.

Q: Is this valve compatible with water and other fluids?

A: Yes. This full-port check valve is designed primarily for water at normal operating temperatures. The 304 stainless steel body also offers excellent corrosion resistance, making it suitable for a broad range of general fluid and pneumatic media in standard temperature conditions.

Q: What does "one-way" or "check valve" mean?

A: A one-way check valve allows fluid or air to flow in only one direction. When flow reverses, the valve automatically closes, preventing backflow and protecting your system's components, pumps, and pipework from damage caused by reverse pressure.
