Dry System Valves

Dry System Valves - Professional Fire Protection for Freezing Environments

Dry system valves are specialized differential-pressure fire protection components designed for sprinkler systems in unheated spaces where traditional wet systems would freeze. These UL 260 listed valves use compressed air or nitrogen instead of water-filled pipes, automatically releasing water when heat activates a sprinkler head.

Technical Excellence: Our dry system valves feature ductile iron construction with stainless steel clappers, handling 175-300 psi working pressure across 2" to 8" pipe sizes. Each valve includes essential trim packages with quick-opening devices, air maintenance systems, and supervisory pressure switches for complete system integrity.

Critical Applications: Perfect for unheated warehouses, loading docks, parking garages, cold storage facilities, and data centers where water damage must be minimized. These valves ensure reliable fire protection in temperatures down to freezing while maintaining NFPA 13 compliance and FM Global approval standards.

Complete your fire protection system with our pressure relief valves for optimal safety performance. For specialized pressure control in dry pipe systems, explore our pressure reducing valves designed for seamless integration.

Professional installation requires heated valve room locations with adequate maintenance access. All systems include water motor alarm compatibility, nitrogen pressure supervision, and periodic testing capabilities per NFPA 25 standards.
