Fire Protection Valve

Role: Reliable shut-off control for underground and above-ground fire mains.
Key Specs: NRS and OS&Y variants; 300 to 350 PSI (2.1 to 2.4 MPa); sizes 2 to 16 inch.
Materials: ASTM A536 ductile iron with internal and external fusion-bonded epoxy coating.
Applications: Main water lines, post indicator assemblies, and municipal grids.

Role: Space-saving flow control and visual position indication for sprinkler systems.
Key Specs: Gear-operated with pre-wired tamper switches; 300 PSI; sizes 2 to 12 inch.
Design: EPDM encapsulated disc for bubble-tight sealing and minimal pressure drop.
Applications: Fire pump assemblies, floor control stations, and system risers.

Role: Preventing reverse flow and water hammer in suppression networks.
Key Specs: Single-door swing and dual-plate wafer designs; rated to 300 PSI; bronze/stainless steel trim.
Applications: Pump discharge lines, cross-connection control, and riser isolation.

Role: Specialized flow control for wet, dry, and deluge sprinkler configurations.
Key Specs: Vertical mount with integrated pressure switch, retard chamber, and trim kits.
Applications: Data centers, aircraft hangars, and high-hazard industrial facilities.

Multi-story standpipe systems rely on high-pressure, certified flow isolation at upper elevations to maintain steady suppression performance during emergencies.

Extensive facility yards utilize resilient-seated gate valves and post-indicator setups for immediate zone isolation and minimal long-term maintenance.

High-rack storage networks depend on precise deluge and pre-action valve arrays to deliver rapid water suppression while mitigating accidental discharge risks.

Water supply grids and pumping stations require heavy-duty swing check and butterfly valve arrangements designed to withstand continuous line pressure and severe water hammer.
