The Prescor pressure-reducing valve stabilises the fluid pressure in a water distribution system to a preset value. It is used on potable water installations for water supply within buildings according to EN 806-2.
Working principle
The Prescor PRV can be adjusted to the required working pressure by turning the regulation knob, which then adjusts the calibration spring pressing against the membrane, which in this case then acts against the valve cartridge. The water pressure downstream of the pressure-reducing valve maintains a pressure in the opposite direction, balancing the valve closed. When the valve is closed, the two forces are balanced. While there is a flow, the downstream pressure decreases, and the spring overcomes the pressure, thus opening the valve and allowing the water to pass through.
Comfort and efficiency without noise and vibrations. The special internal construction of the valve body with perfectly finished surface has been designed to create a minimum flow resistance, limiting vibrations and pressure loss.
Fast and simple pressure setting and commissioning. The regulation knob with indicator allows the PRV to be adjusted easily to the set pressure to simply and quickly set the pressure (1-6 bar). The graduating scale of the PRV gives clear indications of the set pressure.
Pressure under control in every situation. The enhanced mechanical strength of the valve body and its internal parts allows to use of the valve in water supply systems, where the pressure may reach values up to 25 bar.
