Plastic butterfly valve superior performance
Plastic plastic butterfly valve is used together with the rotation of the disc for the opening and closing pieces, in order to achieve the valve opening, closing and regulation. In addition to the butterfly valve in the pipeline cut off and intercept, in recent years has been the sealing performance as the main indicator of evaluation, favored by the market. In addition, the butterfly valve also has the advantages of small size, light weight, simple structure, compared with the same parameters of the valve, reducing the average weight of 30 to 50%, the butterfly plate can be rotated 90 degrees Kai, closed process, By the media force is approximately equal torque opposite, so opening and closing torque smaller. 1, The valve body material should be made of PPH, RPP, PE, PVDF, CPVC, UPVC raw material. The sealing seat is made of EPDM or FPM. 2, the valve body and the pipeline through the flange on the clip-on connection, the connection standard can meet the DIN, GB, ASTM, JIS and other standards, so that the overall pipeline system to achieve uniform standards. 3, the valve design and testing strictly in line with Q / ZBT02-2004.
The blind plate is mainly used to completely isolate the production medium and prevent the production from being affected or even causing accidents due to the loose closing of the shut-off valve
