Our check valves are trusted by global OEMs and distributors for stable operation and long service life.

FAQ

Q1: What is the main advantage of a magnetic-assisted check valve?

A: The magnet helps ensure the valve closes fully even under low differential pressure, preventing backflow more reliably.

Q2: When should I choose NBR vs stainless steel flapper?

A: NBR is ideal for standard refrigerants and oil, while stainless steel is recommended for higher temperatures or aggressive refrigerants.

Q3: Are these valves suitable for both liquid and gas lines?

A: Yes, our magnetic check valves can be used on both liquid and gas lines in refrigeration or HVAC systems.

Q4: Do you offer OEM manufacturing?

A: Absolutely. We provide OEM services with customized sizes, pressure ratings, and branding to meet your project needs.

Q5: What certifications do your check valves comply with?

A: Valves are produced according to international standards, with ROHS compliance. Specific certifications can be arranged upon request.
