Siemens electric pressure reducing valve installation considerations: 1, convenient for operation and maintenance, Siemens electric pressure reducing valve usually upright installation in horizontal pipe runs. 2, pressure reducing valve installation must be in strict accordance with the direction of the arrow on the valve body to keep consistent with the direction of fluid flow. If the water is not clean, some impurities, must be installed in reducing valve upstream water inlet filter. 3, in order to prevent the overpressure Industrial Valves after pressure, should be in the valve outlet of no less than 4 m to install a pressure reducing valve. 4, pressure reducing valve in the pipeline, play a role in check, in order to prevent the harm of water hammer, also can install small expansion tank, to prevent damage to the tube and valve, filter must be installed in front of the inlet pipe of the pressure reducing valve, the expansion tank must be installed after the valve outlet pipe. 5, if you need to install the pressure reducing valve in hot water system, you must be installed between the pressure reducing valve and expansion tank check valve. Both to expansion tank to absorb the increase due to thermal expansion of the volume of water, and can prevent the reverse flow of hot water or pressure fluctuations on the influence of the pressure reducing valve, to ensure that Siemens electric pressure reducing valve normal work for a long time.
