RELIABLE DDX Valve for Fire Protection Systems & Professionals

Equip your commercial and industrial fire protection assemblies with the Reliable DDX Valve, engineered for precise water flow management and robust control during critical fire events. This valve installs directly into wet, dry, electronic, or deluge-dry system configurations, supporting single and double interlock preaction setups as well as low-pressure dry pipe systems. Advanced single and double interlock technologies prevent false activations and leakages to maintain system readiness without unwanted water release, while dry configurations safeguard against pipe damage in freezing environments.

Built for demanding infrastructure, the assembly utilizes a corrosion-resistant metal alloy construction to extend service life and withstand high-pressure conditions up to 175 PSI on select configurations. Maintenance is streamlined through integrated butterfly valves, supervisory trim, and an external reset that removes the requirement to remove the face plate, directly reducing downtime and labor expenses on the job site.
