Fire Protection
Listed and approved valves for sprinkler systems, hydrants, fire pumps and standpipes, built to hold the line when a system has to perform first time, every time.
Fire protection is a life-safety service, so the valves that isolate, control and protect a system carry an unusually high burden of reliability. A sprinkler, hydrant or standpipe network can sit dormant for years and then be called on to deliver full flow within seconds, which means every isolation and check valve in the line has to be specified, listed and supervised accordingly.
Purple Valves supplies the gate, butterfly and check valves that form the backbone of fire water systems across commercial, industrial and infrastructure projects. Our range is selected for tight shut-off, low friction loss and the third-party listings that approving authorities and insurers require.
Common Challenges in Fire Protection
Guaranteed performance after long dormancy
Fire systems are rarely operated yet must work on the first attempt. Valves need resilient seats, corrosion-resistant internals and supervisory provisions so they remain fully operable for the life of the system.
Listed and supervised control valves
Standards such as NFPA 13 require every control valve to be listed and electrically supervised so a closed valve is detected immediately. Component selection has to satisfy both the standard and the local authority having jurisdiction.
Water hammer and friction loss
Rapid closure can generate damaging pressure surges, while excessive friction loss starves sprinkler heads. The right balance of valve type, seat design and actuation protects the pipework and the hydraulic design.
Recommended Valve Types
Resilient-Seated Gate Valves
OS&Y and NRS gate valves give a clear visual position indication and very low friction loss, making them a long-standing choice for main control and isolation on fire water mains.

Grooved & Wafer Butterfly Valves
Listed butterfly valves offer a compact, quarter-turn control valve with integral supervisory switches, ideal for zone isolation, riser control and fire pump lines where space and rapid response matter.

Swing & Wafer Check Valves
Check valves prevent reverse flow on pump discharge and standpipe risers, protecting the supply and holding the system primed for instant response.
