how to correct installation requirements

1. Before the pressure reducing Industrial Valves shall be designed and installed filters in order to protect pressure reducing valve, prolong service life. For piping system must be flushed before installation of pressure reducing valve cleaning, in order to prevent the welding slag, scale and other dirt into the Industrial Valves, valve normal work.

2。 Pressure reducing valve should be set before the cut-off valve, generally installed in front of the filter, to cut off the water when is convenient for maintenance. In order to ensure the normal maintenance of the product and uninterrupted water supply, should adopt parallel installations, the valve should be set up before and after the stop Industrial Valves.

3。 40 mesh filter should be used when using liquid, gas should be used when the 80 - mesh.

4。 Before and after the pressure reducing valve, such as setting pressure gauge, pressure gauge and relief valve imports or exports should maintain a distance more than 5 dn.

5。 Used in gas, the volume expansion behind because of the pressure reducing valve, so please use the expansion pipe, outlet pipe.

6。 Using a liquid, as far as possible using the straight pipe, the length of the straight pipe to the valve diameter of 10 ~ 20 times ( Minimum 500 mm)

7。 Pressure reducing valve outlet ends should be set up soft joints and discharge tube, ease of installation and maintenance.

8。 Pressure reducing valve in the pipeline failure is mainly caused by foreign body, so in front of the fluid through the relief valve should be fully cleaning pipe ( About 30 minutes) 。

9。 Relief valve can be installed in vertical or horizontal, as shown in the installation direction of pressure reducing valve should be paid attention to in and out of the water, not upside down.
