Dual Plate Iron Check Valve | 452 Series | Wafer Style | NBR Seat

The 452 Series Dual Plate Iron Check Valve is a space-saving, high-performance non-return valve designed for demanding water, HVAC, and industrial fluid systems. Featuring a cast iron wafer-style body and nickel-plated ductile iron discs, it ensures reliable backflow prevention with increased corrosion resistance. The spring-loaded dual plate configuration minimizes pressure drop and reduces water hammer compared to conventional swing check valves.

Equipped with a durable NBR seat, the 452 Series operates efficiently up to 150 PSI (WOG) and 180°F, making it ideal for clean water applications in commercial and mechanical systems.

Key Features:

• 150 PSI WOG Rated – Handles standard pressure requirements in most HVAC and fluid systems
• Dual Nickel-Plated Discs – Spring-loaded design enables fast shutoff and longer life compared to swing checks
• Compact Wafer Body – Fits between ANSI flanges for easy installation and reduced weight
• Corrosion-Resistant Internals – Stainless steel springs and pins with PTFE washers for smooth operation
• NBR (Buna-N) Seat – Reliable sealing for water and compatible fluids up to 180°F

Applications:

• HVAC piping systems
• Pump discharge lines
• General water & process fluid systems
• Commercial mechanical rooms
• Irrigation and water distribution
