Pressure Reducing Valves

Pressure reducing valve is a pressure regulator that automatically cuts off the flow of liquid or gas at a certain pressure. These PRV valves are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and usable pressure for various applications. Temperature varies from -40 degree Celsius to +250 degree Celsius with the frequency of 50Hz/60Hz and speed of water-flow is up to 200 meter cube per hour with the pressure range being up to 50bar.

Detailed Description for Pressure Reducing Valves

The water pressure reducing valve is a device which is commonly installed at the water mains which reduces and regulates the pressure entering from public places and public networks irrespective of the stream variations. And if required, this valve can be entirely disassembled from the top which makes it easier to maintain and inspect and it is, therefore, not necessary to remove the appliance from the pipe to perform the same.


Types of Pressure Reducing Valves:

Steam, liquids and gases usually flow at a higher pressure to the point of final use. And at these points, these pressure relief valves lowers the pressure for safety and more efficiency. There are three types of such valves.

1. Direct acting: This is the simplest valves amongst all. This valve operates with either a flat diaphragm or convoluted bellows. Being self-contained, it does not need any sensing line downstream to operate. It is the smallest and most economical of the three. Accuracy varies between -10% to +10%. 

2. Internally piloted piston-operated: This type of PRV comprises of two valves-a pilot and main valve-in one unit. The discharge from the pilot valve acts on top of the piston which opens at main valve. Greater capacity per line size. Greater accuracy than the Direct Acting valve; +/- 5%. 

3. Externally piloted: This valve replaces the piston operator of internally piloted design with double diaphragms. The increased diaphragm area can open a large main valve, enabling a larger capacity per line size than the internally piloted valve. Accuracy is +/- 1%.


Advantages and benefits of Pressure Reducing Valves:

High pressure is a major cause of water leakage, pipe damage or even wastage of water. Everyone appreciates good water pressure in the home. In that case, pressure reducer valves are of great benefit.

·         Enable stable and reliable pressure of water for household systems.

·         Reduces risks of water-leakages.

·         Decreases the energy required to heat water for showers, washing machines etc.

·         Limits water wastes by lowering and controlling flow rates.

·         Automatically conserves water when used in high pressure areas.
