How do your relief valves work?

CPV relief valves operate by using a spring-actuated mechanism to open when the pressure in the system exceeds a predetermined set point. This allows excess pressure to be released, maintaining system integrity.

What is their typical lifespan?

CPV relief valves are renowned globally for their unmatched strength and dependability. We engineer them to last for thousands of life cycles.

Do you have different valve end connectors?

Yes, CPV offers various valve end connectors to accommodate a wide range of installation requirements.
