Technical Specifications • Size Range: 2' to 36' (50mm to 900mm) • Pressure Class: Class 150, 300, 600 • Design Standards: API 6D / API 594 • Face to Face: API 6D / API 594 • Body Type: Wafer • End Flanges: ANSI B16.5 / ANSI B16.47 / DIN / BS / IS • Materials: CI / CS / SS 304 / SS 316 / SS 304L / SS 316L / Hast Alloy / Monel / Special Metals • Seat Options: Viton Seat Rings, Hard Surface, Rubber Lined • Testing Standards: API 598 / BS 6755 • Operation: Self-operated, spring-loaded dual plate How Dual Plate Check Valves Operate Unlike traditional swing check valves, the Dual Plate Check Valve Non-Return Valve uses two spring-loaded plates mounted on a central hinge: • Forward Flow: Fluid pressure smoothly opens both plates, allowing full flow with minimal resistance. • Reverse Flow: Internal springs quickly close the plates as flow slows or reverses, sealing the valve instantly and preventing backflow. This rapid response reduces pressure surges and ensures safe handling of liquids, gases, and other fluids without the need for external power. Key Design Features 1. Compact Wafer Construction: Perfect for installations with limited space between flanges. 2. Spring-Loaded Dual Plates: Ensures quick closure and stable performance under fluctuating flow conditions. 3. Material Versatility: Available in CI, CS, SS 304, SS 316, Hastelloy, Monel, and specialty alloys for aggressive services. 4. Reliable Seating Options: Viton Seat Rings, Hard Surface seats, or Rubber Lined configurations for consistent sealing. 5. High-Temperature Capability: Performs reliably in demanding industrial environments. Performance Advantages • Effective Backflow Prevention: Protects pumps, compressors, and pipelines from reverse flow damage. • Low Pressure Loss: Streamlined flow path reduces turbulence and energy loss. • Automatic Operation: Fully self-operated, requiring no actuators or control systems. • Extended Service Life: Robust materials and design ensure long-term durability.
