Dual Plate Check Valves – High Efficiency Non-Return Solution Dual Plate Check Valves are advanced non-return valves designed to overcome the limitations of traditional swing and lift check valves. With a compact, lightweight, and robust construction, these valves offer superior performance while occupying significantly less space in piping systems. The valve features two spring-loaded plates mounted on a central hinge pin. As fluid flows, the plates open smoothly, and when the flow decreases, they close instantly using torsion spring action—without requiring reverse flow. This intelligent design ensures non-slam operation and completely eliminates water hammer effects, making it ideal for sensitive and high-performance systems. Due to its silent operation, it is also known as a Silent Check Valve or Wafer Check Valve. Designed for versatility, these valves are suitable for a wide range of industries including oil & gas, petrochemical, HVAC, and power plants. They are available in both soft seated and metal-to-metal seated configurations, allowing use in low as well as extreme temperature and pressure conditions. Key Features: Size range from 2” to 120” Pressure ratings from ANSI Class 125 to Class 2500 API 6A range from API 5000 to API 10000 Suitable for temperature range -196°C (cryogenic) to 900°C (fire-safe applications) Available in Wafer, Double Flanged, Lugged, Butt Weld, Hub Ended, and RTJ designs Optional Jacketed and Cladded body constructions Fugitive emission-free, retainer-less design Optimized spring for over 1 million cycles Zero velocity non-slam closure Eliminates valve-induced water hammer Compliance with API 594, API 598, API 6D, BS 6364, API 6FA standards Dual Plate Check Valves provide a reliable, maintenance-friendly, and energy-efficient solution for preventing backflow while ensuring smooth and quiet system operation.
