Pressure Reducing Valves (PRVs) ensure that an appropriate and comfortable water usage pressure is available at all times. These valves enable the control of pressure from boosted cold water supplies to match site requirements.

In high rise buildings, PRVs are located on every floor or every few floors, for protecting the department’s plumbing and low rated fittings & connections from overpressure.

The pressure reducing pilot commands the valve to throttle/close when the downstream pressure increases ABOVE the pilot pressure set point and to open the valve when the downstream pressure decreases to BELOW the pilot pressure set point.

*This example refers to 3-way control method. In Waterworks and Buildings 2-Way is common as well, which has somewhat different principles of operation.

The BEECO Friendly Reduced Pressure Zone Backflow Preventer is designed to stop the reverse of flow of a liquid into a potable water system.

When downstream pressure is equal to the required set-point, the pilot keeps the water in the control chamber and the valve remains in the same position, not opening or closing, and thus retaining the set pressure.

When downstream pressure is lower than the required set-point, the pilot drains water from the control chamber to the atmosphere and the valve opens.

While in Irrigation & Fire Protection, flow is constant and occurs in shifts/pulses, depending on the crops or firefighting emergency events.

A pressure regulator is a spring-loaded valve that regulates pressure on the downstream (house) side of the valve. Altering the degree of spring compression ...

In municipal networks pressure reducing valves (PRV) are required at the inlet of pressure zones or DMAs (District Metering Areas). On the one hand, for protecting the equipment at the downstream and  household plumbing  from overpressure. On the other hand, guaranteeing sufficient & reliable pressure for the consumers.

When downstream pressure is higher than the required set-point, the pilot allows water to flow from the upstream to the control chamber and the valve tends to close.

In Irrigation PRVs are required in water headers in the entry of lower elevation fields, pivot-machines, low pressure systems like dripping pipes and more.

System pressure can vary due to many different reasons. Pumps starting, changes in topography, pipe characteristics, the resistance of equipment along the system, leaks & water theft and of course the demand flow pattern which has a direct effect on the pressure loss across the pipeline.

The wide range of valves offer a variety of water pressure options to suit a number of different applications that could include more demanding projects such as; tall buildings like hotels and residential/commercial tower blocks.

Some rely on a 3-way control loop and others on 2-way. Some are full bore for minimal head loss during insufficient inlet pressure and others are reduced bore for achieving efficient pressure regulation.

Hydraulically operated pressure reducing control valves reduce a higher upstream pressure to a constant lower downstream pressure, regardless of fluctuating demand or varying upstream pressure.

Some have throttling devices to cope with low flows, and others have different mechanisms to eliminate/reduce cavitation.

The hydraulic pressure reducing valves are equipped with a pressure reducing pilot designed to hydraulically sense the downstream pressure.
