Wafer Type Check Valve – Key Advantages
Space-Saving & Lightweight Design
Ultra-compact profile fits seamlessly between standard pipe flanges.
Ideal for tight spaces, eliminating the need for bulky supports.
Cost Efficiency & Low Maintenance
Simplified construction lowers material and production costs.
Easy installation reduces labor time.
Superior Flow Performance
- Low pressure drop ensures energy-efficient operation.
- Smooth disc mechanism minimizes turbulence and noise.
Rapid Shut-Off Protection
Spring-assisted closure prevents water hammer and backflow damage.
Reliable sealing in milliseconds for system safety.
Durability & Versatility
Robust materials (cast steel, stainless steel, alloy steel) resist corrosion and high pressure.
Suitable for water, chemicals, oil/gas, and industrial applications.
Bidirectional Installation
Flexible mounting in horizontal or vertical pipelines.
Reduces layout constraints for complex systems.
Wafer Type Check Valves combine simple yet robust construction with reliable performance. Specifically engineered for applications requiring minimal pressure drop, these valves ensure efficient flow control with low energy loss.
Our Wafer Type Swing Check Valve features compact face-to-face dimensions and lightweight construction, enabling space-saving installation between standard pipe flanges. Compared to traditional swing or forged check valves of equivalent diameter and pressure ratings, this design offers a lighter and more cost-effective solution without compromising durability.
Wafer Type Dual Plate Swing Check Valve
Dual-Plate Check Valve, API 594 Valve, Zero-Leakage Check Valve, Low Water Hammer Valve, Full-Bore Pipeline Valve
Retainerless Body: Zero-emission design with no body wall penetrations—drilled-thru or double-flange ends prevent external leakage.
Lightweight Dual Discs: Reduced inertia minimizes water hammer and slamming in oil, gas, or chemical pipelines.
Horizontal Hinge Optimization: Side-mounted hinges eliminate gravity drag, lowering energy costs in horizontal installations.
Full-Bore Flow: Maximized flow area with ultra-low pressure drop; internal retention avoids gasket interference.
Spring-Assisted Closure: Rapid response to flow reversal, reducing stress on hinges and extending service life.
Shock-Absorbing: Protect discs and hinges from wear in high-velocity or frequent cycling applications.
Self-Aligning Hinge Pins: Clearance design prevents disc dragging, ensuring long-term seat integrity.
