Product Features
  • Pressure Seal Design: High-integrity sealing performance under various pressures.
  • Unique Cage Unit: The entire seat-hinge-pin-disc assembly can be tested outside the valve before seal welding, eliminating pin seal leakage.
  • Easy In-line Service: Designed for convenient maintenance without removing the valve body from the pipeline.
  • Efficient Operation: Hinge pin located near the center of gravity allows the disc to move rapidly without sliding or wear, preventing "water hammer".
  • Superior Tightness: Conical, lapped-in hardfaced seating is self-aligning. Suitable for vertical piping with upward flow.

Frequently Asked Questions (FAQ)
1. What is the size range for these dual plate check valves? We offer a wide size range from DN50 up to DN900 to accommodate various industrial piping requirements.
2. What are the primary materials available for the valve body and disc? The valve bodies and discs are available in Cast Iron, Ductile Iron, Carbon Steel, Stainless Steel (CF8/CF8M), and Aluminum-Bronze.
3. What is the maximum working pressure and temperature range? The valves are designed for low-pressure applications with a standard working pressure of 10-16 Bar and an operating temperature range of -10ºC to +120ºC.
4. Which international standards do your check valves comply with? Our products comply with multiple standards including ANSI B16.1, EN1092-2, ISO 7005, JIS B2220, and design standards like EN12334 and ISO 5752.
5. How does the "unique cage unit" benefit the valve performance? The cage unit allows the entire internal assembly to be tested for integrity before it is sealed into the body, which effectively eliminates potential pin seal leakage.
6. Are these valves suitable for seawater or chemical applications? Yes, by selecting specific materials like AL-Bronze for the body/disc and suitable seat materials (like EPDM or NBR), these valves are ideal for seawater, desalination, and chemical processing.
