Before installing the valve make sure the piping is free of foreign material, scale, etc. Pressure reducing valve installations require accurate design of both inlet and outlet pipework. (fig.1). The Fillmatic valve is factory set for 12 psi (83 kPa). Features & Benefits: (See Figs. When the entering pressure from the public mains is too high and variable, pressure reducing valve stabilizes the downstream Like Watts on Facebook at http://www.facebook.com/wattsbrand Is your water pressure too high or too low? Has sensing element for reduced pressure which directly actuates the valve. 1. 1. Request Proposal. The valve should be installed in horizontal pipework with its axis vertical. 3. It may be built right into your water meter. If your water pressure doesnt seem to be as strong as it once was or you notice a significant loss of pressure when you use more than one fixture at the same time, your pressure reducing valve may be bad. Replacing a bad valve can be a nightmare if you do not have valves on either side of the pressure valve. Pressure Max: 400 Psi and Temp Max: 1800 F (800 C). The valve must be compatible with the system design, pressure & temperature requirements and must also be suitable for the fluids it is intended to carry. PRESSURE REDUCING VALVES 5.1 THE PRESSURE REDUCING VALVE DOES NOT MAINTAIN THE ADJUSTED FIGURE In most cases, this problem is due to the presence of impurities on the valve seat, causing blow-by and consequent increase in the downstream pressure. 4. 3. A Pressure Reducing Valve can be defined as a self Relieve pressure between valve and PRV by opening blanking plug and allowing water to go out. The 500XL3 Pressure Reducing Valve works effectively for industrial water lines and commercial systems, with high-flow rate capacity and low falloff. Sometimes this valve is also known as pressure reducing regulator. Assembling pilot to Pressure reducing valves should be checked periodically (at least yearly), to verify that they are operating correctly and to clean the internal parts and screen (if any). 2. A pressure-reducing valve is used in the water supply system to reduce the pressure of the incoming water before it enters your house. This reduces the amount of energy required to move the water through pipes, which can save money on your monthly utility bill. It also helps prevent damage to pipes and fixtures from excessive water flow. 4.3 Removing and Checking Cartridge Internals. It is compact and light weight, and ideal for controlling small flow rate. Some of the key points important to know about PRVs include: They are speciality valves, designed to provide ongoing long-term protection against excessive pressure coming from a mains supply, boosted or tank-fed/gravity source. Unscrew the bellows retainer (key 8) from the pilot body. The all-bronze body, stainless-steel stem and cartridge internals provide superior corrosion resistance and increases product life offering the 3. Pressure Reducing Valves are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level.
