The Mdl 210S Swing Check Valve is engineered specifically for anti-freeze loops in fire protection systems, providing reliable backflow prevention under harsh chemical and cold conditions. Designed for fire protection engineers, contractors, and maintenance professionals, this valve ensures durability and consistent performance in freeze-prone environments.

• Corrosion-Resistant Construction: Fabricated from materials that withstand chemical exposure and thermal cycling typical in anti-freeze sprinkler loops, extending the valve’s operational lifespan.
• Precision Stainless Steel Hinges: Internal hinges crafted from high-grade stainless steel enable smooth, low-resistance swing action, helping maintain optimal flow and reducing hydraulic losses.
• Elastomer Seals: Durable elastomer sealing components provide a secure and tight closure, effectively preventing backflow and contamination within fire protection systems.
• Regulatory Compliance: UL 312 listed and FM approved, the valve meets stringent fire safety standards and aligns with NFPA 13 and NFPA 25 codes for installation and inspection.
• Versatile Compatibility: Designed to fit standard fire protection piping with options for NRS threads and flanged ends, offering straightforward installation or retrofit in commercial and industrial setups.
• Optimized for Anti-Freeze Loops: Specifically developed to handle temperature fluctuations and anti-freeze fluids with minimal mechanical wear, improving reliability in freeze-prone conditions.

By incorporating the Mdl 210S Swing Check Valve into your fire protection anti-freeze system, you prevent reverse flow that can compromise sprinkler integrity and cause freeze damage. This valve tackles common challenges such as seal degradation and hinge corrosion experienced by standard valves not made for chemical and thermal stresses, resulting in reduced maintenance and longer service life. Its quick, dependable closure safeguards critical components during low-temperature events, ensuring uninterrupted fire protection and compliance with safety regulations in demanding environments.
