Frequently Asked Questions
-
What is the maximum working pressure of this valve?
The valve is rated for Class 600, which corresponds to a maximum working pressure of 600 psi (approximately 41.4 bar) at ambient temperature. Higher pressures are possible with custom designs. -
Can this valve be used for natural gas applications?
Yes, the 304 stainless steel construction and spring-loaded design make it suitable for natural gas, provided the gas is clean and dry. For sour gas, we recommend a special material upgrade. -
What is the standard lead time?
For standard sizes (2"–12"), lead time is typically 15–25 working days. Larger sizes or custom orders may require 30–45 working days. Please confirm with our sales team. -
Does the valve come with any certifications?
Yes, our manufacturing facility is ISO9001 certified. The valve is designed and tested according to API 6D and API 598 standards. Additional third-party tests can be arranged upon request. -
How do I install the wafer check valve?
The wafer check valve is installed between two flanges using bolts. Ensure proper alignment and gasket placement. The spring-loaded disc closes automatically when flow reverses. For detailed instructions, refer to our installation manual. -
What seal materials are available?
Standard seal material is PTFE. For high-temperature applications, graphite seals can be provided. Both are resistant to petroleum oil and common chemicals. -
Can I get a custom size or pressure rating?
Yes, we offer customization for size, pressure rating, end connections, and materials. Please contact us with your specific requirements. -
What is the warranty period?
