Dual Plate Watercheck Valve

Dual plate wafer check valves are high performance non-slam check valves. The dual plate design is stronger, lighter and smaller compared to a normal swing check valve or non-slam check valve. It also has the advantage of no water hammer. It’s a maintenance free valve with a long life-time.

Available in a size range from 2” to 36” and an ANSI class range of 150-2500.

Advantages

• Dual-plate designs that are compact and lightweight for efficient seating, operation and lower installation cost
• Independent springs with long legs to prevent seat scrubbing and provide non-slam performance
• Retainerless valve design without body penetration for critical service applications
• No Fugitive Emissions
• Metal to metal sealing
• High degree of shut-off
