Low-Lead pressure regulating valve replacement insert for 1 and 1-1/4 inch valves. | Privacy Policy. Ensure that the downstream isolating valve on the main line where the reducing valve is located is closed. Once this starts, it will only get worse. residential products . 2021 0000003061 00000 n
If there is good pressure on the cold and not the hot it may be an issue with the water heater or the fixture itself. pressure reducing valve. The upstream gauge is not critical, whereas the downstream gauge is if you want to set the valve accurately. Prior to turning off the water, you should check the pressure using a pressure gauge. INSTALLATION INSTRUCTIONS for PRESSURE REDUCING REGULATOR VALVES SERIES E3, E41, and E56 PURPOSE To reduce a higher inlet pressure to a lower outlet pressure, and automatically control the lower (or set/controlled) pressure. 3. 0000042366 00000 n

The inlet piping should be short and direct. If it isn’t, the flow will be restricted and the valve won’t relieve as much capacity as it’s supposed to. Remove the ºî plug on the inlet side of the main valve body (1) (for GP-2000 remote mount pilot and OB-2000 temperature pilot) with an allen wrench. Tomson PRV series pressure reducing valves are factory set at 350 kPa or 500 kPa. The pressure-reducing valve should always be installed on a horizontal steam line, never vertically. Doing this can cause simmer and leakage. installation guide. Sort by: shop our product catalog. 3. Before you can begin to install the water pressure reducing valve, you should take care to turn off the water at the main supply line. The solution is to install pressure reducing valves (PRVs) to bring the overly high water pressure at these levels back down to acceptable standards. equipment productivity, but also shortens the life of pressure reducing valves.
