The Prescor pressure reducing valve stabilizes the fluid pressure in a water distribution systems 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, this 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 perfect 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 the valve in water supply systems, where the pressure may reach values up to 25 bar.
Outlet settings (Ps) from 1 to 6 bar.
Ps value set during testing: 3 bar.
Outlet Ps set tolerance on varying inlet pressue: pressure according to EN 1567.
Maximum working pressure: 25 bar.
Min./Max. working temperature: 0 ˚C (excluding ice) / 80 ˚C.
Suitable for addition of glycol-based anti-freeze up to 50%.
Flamco has been involved in the development, production and sale of high-quality components for use in HVAC systems since 1956. It is part of the stocklisted Aalberts NV, instituted in 1975. Along with Comap, which helps manage water and energy through its thermal and sanitary products that increase comfort in buildings, the Aalberts hydronic flow control business unit was constituted. Stronger together, Flamco and Comap will continue to build mission critical technologies to manage heating and cooling humanly with better financial and environmental efficacy. From source to emitter we partner with our customers to engineer seamless energy efficient hydronic systems for their building requirements.
