Pressure Reducing Valve (PRV)

what is Pressure Reducing Valve (PRV)?

One of the problems of many multi-story buildings is the reduction of water pressure and water not reaching the upper floors. Also, this reduction in pressure can cause problems in the operation of fire fighting equipment such as sprinklers, fire boxes and hose rails.

For this purpose, pumps are used in buildings to increase pressure. But when the pressure increases in the lower floors, it can lead to damage to the piping system and fire fighting facilities.

As a result, in order to solve these problems, a device called a pressure reducing valve is used.

Pressure reducing valve (PRV) is one of the important elements in firefighting systems. These valves are used to reduce and control water pressure in firefighting systems and prevent dangerous pressure increases for pipes, fittings, and firefighting equipment. They allow water pressure to enter the firefighting system at a safe and appropriate level so that in case of fire, water can be injected to the required points at the right pressure.

Features of the fire-fighting pressure relief valve include the following:

1. Pressure reducer: The main function of these valves is to reduce the water pressure entering the firefighting system to provide the appropriate pressure for sprinklers or other firefighting equipment.

2. Adjustability: Most PRVs have adjustable settings that allow users to fine-tune the required pressure.

3. Resistance to shocks and sudden pressures: these valves must have the ability to withstand sudden pressures in case of sudden connection to the water network.

4. Accurate pressure control: PRVs must be capable of accurate pressure control to maintain the required pressure over time.

5. Compliance with standards: These valves must comply with standards related to fire extinguishing systems (such as NFPA 13).

Pressure reducing valves are very important in firefighting systems because proper water pressure in sprinklers and other equipment is critical. If the water pressure is too high, pipes or fittings may break and release large amounts of water, which can lead to damaging equipment replacement and building damage.

In other words, PRVs act as one of the key elements in fire protection as well as pressure control in firefighting systems.

Types of pressure relief valves

Direct pressure relief valve
Valve with pilot function
Diaphragm valves
Piston valves

Features and applications

Water pressure control at specified values (even in case of fluctuations in pressure)
Adjusting the water pressure evenly on all floors of the building (suitable for firefighting use)
Increases the life of piping, connections and firefighting equipment (due to pressure regulation in the pipes)
It prevents water hammer (blue hammer) from occurring in connections and water supply equipment
By using pressure adjustment by valve, water consumption in buildings and structures can be reduced by 30%
Reducing costs (due to proper pressure adjustment and thus reducing consumption)
It is very easy to use the fire extinguisher
