Butterfly Valve Installation And Use

Kaitai Valve Group Co.,Ltd | Updated: Aug 01, 2017

              the purpose of using check valve is to prevent the upstream of the media, generally in the export of pumps to install check valve. In addition, check valves are also installed at the outlet of the compressor. In short, in order to prevent the media upstream, the device, device or pipe should be installed on the road check valve. Vertical lift check valve is usually used in the horizontal pipe on the nominal path 50mm. Straight-Through lift check valves can be installed on both horizontal and vertical pipes. The bottom valve is generally only installed on the vertical pipe inlet of the pump, and the medium flow from bottom to top.Butterfly Valve

              Swing check valve can be made into a very high working pressure, PN can reach 42MPa, and DN can also be very large, the maximum up to 2000mm above. Depending on the material of the shell and seal, any working medium and any operating temperature range can be applied. The medium is water, steam, gas, corrosive medium, oil, food, medicine and so on. Medium operating temperature range between-196~800℃.Butterfly Valve

              The installation location of the swing check valve is not restricted, usually installed on the horizontal pipe, but can also be installed on the vertical pipe or inclined pipe. The application of butterfly check valve is low pressure large caliber, and the installation situation is limited. Because the butterfly check valve's work pressure cannot do very high, but the nominal diameter can do very big, can reach above 2000mm, but the nominal pressure is in 6.4MPa below. Butterfly check valve can be made to clamp, generally installed in the pipe between the two flanges, the use of the form of the clamp connection.Butterfly Valve
