445 Dual Plate Iron Check Valve

Engineered for extreme environments, the 445 Dual Plate Iron Check Valve combines a robust wafer-style design with EPDM seats and corrosion-resistant bronze discs. Ideal for steam, hot water, and aggressive media, this valve ensures reliable unidirectional flow while withstanding high temperatures and harsh conditions.

Key Features:

• EPDM Seat Excellence: Resists temperatures up to 300°F (149°C), perfect for steam systems and outdoor applications exposed to ozone/weathering.
• Dual Plate Efficiency: Spring-assisted bronze discs snap shut instantly, preventing water hammer and backflow in high-pressure pipelines.
• Wafer-Style Versatility: Compact, flangeless design installs seamlessly between ANSI B16.1/16.5 flanges, slashing labor and space requirements.
• Multi-Media Durability: Cast iron body and bronze discs thrive in corrosive liquids, gases, or high-velocity fluids.
• 150# WOG Certified: Rated for 150 PSI across water, oil, and gas systems.

Technical Specifications:

• Body Material: Cast Iron
• Disc Material: Bronze
• Seat Material: EPDM (Ethylene Propylene Diene Monomer)
• End Connection: Wafer-style (ANSI compliant)
• Pressure Class: 150# WOG
• Temperature Range: -20°F to 300°F (-29°C to 149°C)

Ideal Applications:

• Steam distribution and condensate return lines
• Chemical and petrochemical processing
• Hot water circulation in HVAC systems
• Oil refinery and fuel transfer pipelines
• Power generation plants

Why Choose This Valve?

The 445 Dual Plate Check Valve stands out in high-temperature and corrosive environments. Its EPDM seats resist aging and degradation from steam/ozone, while the bronze discs prevent corrosion in wet or chemical-laden systems. A top choice for engineers prioritizing thermal resilience, leak-free performance, and minimal maintenance.

Confirm media compatibility for specific fluids and temperatures beyond standard ratings.
