Hose valves play a critical role in some fire protection systems, controlling water flow to hose lines used by the fire department or trained personnel. QRFS carries a wide range of fire hose valves, including angle, straight, and pressure-restricting models designed for standpipe systems and specialty applications requiring hose access points.
Available in grooved connections or NPT threads by NPSH threads, NST threads, New York Fire Department threads, and other local connection types, our valves are engineered for long-lasting performance in demanding environments.
Whether you need valves for a new system installation or replacements for existing fire protection systems, QRFS provides UL listed and FM approved options in brass, chrome-plated brass, and lightweight aluminum.
Our selection of fire hose valves supports hooking up onsite hoses in standpipe systems, ensuring building occupants and firefighters can quickly access controlled water pressure. These valves are engineered to withstand demanding conditions.
Angle hose valves are the industry standard for standpipes due to their compact profile and efficient water-control design. They help minimize hose kinking and support smooth operation during emergencies. Angle valves are commonly installed in stairwells, within fire hose cabinets, and mechanical rooms.
Brass hose valves offer exceptional corrosion resistance and reliability. Available in straight-line and angle configurations, brass valves provide a rugged solution for fire protection systems. QRFS also carries pressure-reducing valves for systems that must deliver high pressure, often to reach higher floors, while also ensuring safe, lower-pressure water delivery at hose access points that require it.
QRFS is a trusted source for fire supply components built to meet industry standards. Our inventory includes:

What is a hose valve, and why is it important in a standpipe system?
A hose valve is a connection point within a standpipe system where fire hoses are attached to access water for firefighting. This part regulates water flow from the standpipe risers and is essential for efficiently accessing pressurized water during an emergency.
What types of hose valves are commonly used with fire hose systems?
The most common hose valves used in fire protection are angle hose valves with threaded outlets designed to connect to standard fire hoses. These valves typically come in 1-1/2″ or 2-1/2″ sizes, and some include pressure-restricting devices for specific system requirements.
How do I choose the right hose valve size for a standpipe system?
Hose valve size depends on the class of standpipe system you’re installing or maintaining. Class I systems (for firefighter use) normally use 2-1/2″ valves, while Class II and III systems may include both 1-1/2″ and 2-1/2″ valves to support occupant and firefighter hose connections.
What are pressure-restricting devices on hose valves used for?
Pressure-restricting devices limit the maximum outlet pressure and flow from a hose valve in systems where high pressure could damage hoses or make handling difficult. Not all standpipe systems require these devices, but they’re important where static pressure exceeds design needs.
Are there compatibility concerns when selecting hose valves for fire protection?
Yes, compatibility matters. Hose valves must match the hose thread size/type of both the standpipe system and the jurisdiction’s hoses, and be suitable for the water pressure and environment in which they’ll be used. Choosing the correct valve ensures hose access during an emergency and compliance with codes, standards, and local regulations.
