150LB 30inch WCB Double Door Wafer Check Valve One Way Valve
Paraments of Double Door Wafer Butterfly Valve
- 150LB: Pressure Rating Rated for 150 PSI (per ASME B16.34), this valve suits medium-pressure applications in water, oil, gas, or steam systems. Its pressure class balances durability with versatility.
- WCB: The valve body is made of WCB (ASTM A216 cast carbon steel). Suitable for non-corrosive environments, WCB is cost-effective for general service.
- Double Door one way Valve Design: Features two spring-loaded, hinged discs that open with forward flow and snap shut instantly against reverse flow. The wafer-style installation fits between ANSI/ASME B16.5 flanges, eliminating the need for separate flange bolts and reducing weight.
- Compact and Lightweight: The wafer design saves space and simplifies installation compared to traditional swing check valves, which is critical for large 30-inch systems.

Applications of Double Door One Way Valve
- Water Treatment Plants: Prevents backflow in pump discharge lines.
- Oil and Gas Pipelines: Safeguards equipment from reverse flow in hydrocarbon transport.
- HVAC Systems: Manages steam or chilled water in large commercial setups.
- Power Generation: Used in cooling water or condensate systems.
Advantages of Dual Disc Check Valve.
- Quick Closure: Spring-assisted discs minimize water hammer and protect pumps.
- Low Maintenance: No lubrication required; resistant to wear in high-flow conditions.
- Cost-Effective: Reduced material and installation costs due to wafer design.
Installation Tips of One Way Flow Valve
- Ensure proper flange alignment (ASME B16.5) and gasket integrity for leak-free performance.
- Install horizontally or vertically, but verify spring tension for optimal disc movement.
- Inspect discs periodically for debris or wear in high-sediment environments.
