Product Overview: A
UL Deluge Valve is an essential component of a deluge fire suppression system. These valves are designed to control the flow of water (or other fire suppression agents) into the deluge system and are activated in the event of a fire to release water to all open sprinkler heads simultaneously. UL (Underwriters Laboratories) certification ensures that the valve has been rigorously tested and meets safety and performance standards in compliance with national and international fire protection codes.
Key Technical Specifications
-
Valve Type:
- Deluge Valve - A valve that remains closed under normal conditions and opens when triggered by a fire detection system (automatic or manual).
-
Operating Pressure Range:
- Minimum Operating Pressure: 10 psi (0.7 bar)
- Maximum Operating Pressure: 300 psi (12.1 bar)
Note: Specific valves may have different pressure limits depending on manufacturer and design.
-
Water Flow Rate:
- Nominal Flow Rate: Typically ranges from 250 to 1500 GPM (gallons per minute) depending on the size of the system and valve capacity.
-
Valve Construction Materials:
- Body Materials: Typically constructed of cast brass, bronze, or stainless steel for strength and corrosion resistance.
- Diaphragm Materials: Synthetic rubber or elastomers, designed to withstand pressure and wear over time.
- Seals: High-quality sealing materials designed to prevent leakage under high-pressure conditions.
-
Activation Type:
- Pneumatic (Air Pressure)
- Electric (Solenoid or Motor-Driven)
- Hydraulic (Water Pressure)
Pneumatic and electric types are most commonly used for UL-certified deluge valves.
-
Valve Size (Inlet/Outlet):
- Common sizes range from 2 inches (50mm) to 10 inches (250mm) in diameter, with larger systems requiring larger valves to handle higher flow rates.
-
Flow Characteristics:
- The valve opens fully and immediately upon activation, allowing water to flow through the entire system at once, as opposed to a conventional sprinkler system, which operates on an individual head-by-head basis.
-
Temperature Rating:
- Standard valves are designed to function within a temperature range of (4°C to 52°C). In special cases, valves can be designed to operate in extreme temperatures (either high or low) depending on the needs of the installation.
-
Pressure Relief Function:
- Some UL deluge valves come with integrated pressure relief features to ensure system stability by controlling the water flow and pressure across the system when the valve opens.
