Fire Sprinkler Valves: Protecting Lives and Property

Jun 22, 2023 | news

Fire sprinkler systems are a crucial component of any building’s fire protection system. They are designed to quickly detect and extinguish fires, protecting lives and property. Fire sprinkler valves play a critical role in the operation of sprinkler systems, allowing for the control and distribution of water to the sprinkler heads.

A fire sprinkler valve is a type of valve that is used to control the flow of water in a fire sprinkler system. It is typically located near the main water supply and is connected to the sprinkler system piping. When a fire is detected, the sprinkler system is activated, and water flows through the sprinkler heads to extinguish the fire.

There Are Several Main Types Of Valves Commonly Used

• Control Valves – These precisely regulate water flow and pressure to sprinkler systems. They maintain a set pressure regardless of water demand.
• Check Valves – These one-way valves only allow flow in one direction, preventing backsiphonage and backflow into water supply lines.
• Alarm Valves – Also called waterflow switches, these automatically send an electrical signal when water starts flowing through the valve. This alerts the central fire alarm system.
• Dry Pipe Valves – Located at the base of dry pipe systems, these maintain air pressure to keep water out until a sprinkler head activates. They then release the air to allow water into the system.
• Pressure Reducing Valves – These throttle flow and reduce high pressure to a set, lower pressure for the sprinkler system.
• Drain Valves – Located at system low points, these valves allow water to be drained from the sprinkler system for testing, inspection or maintenance.

Key Considerations When Selecting Fire Sprinkler Valves Include:

• Pressure ratings – Valves must meet or exceed system requirements.
• Material – Ductile iron, cast iron and stainless steel are common options.
• Certification – Valves should be UL Listed and FM Approved for fire protection use.
• Actuation – Butterfly valves are commonly used for their compact size. They can be manual or actuator-driven.
• Features – Grooved connections, tamper switches, test ports and inspection access are valuable options.

Fire Sprinkler Valves Offer A Variety Of Functions Within Sprinkler Systems Designed

• Automatically release water when needed
• Maintain proper system pressure
• Allow for drainage, testing and maintenance
• Signal the alarm system when water is flowing
• Reduce high-pressure water sources to safer levels
