All plastic butterfly valve

summary:

The all plastic butterfly valve uses a butterfly plate that rotates with the rod as the opening and closing member to achieve the opening, closing, and adjustment of the valve.

In addition to being used for cutting and intercepting in pipelines, butterfly valves have been favored by the market in recent years for their sealing performance as the main evaluation indicator. In addition, butterfly valves have the advantages of small size, light weight, and simple structure. Compared with gate valves of the same parameters, they reduce the average weight by 30-50%. The butterfly plate can be opened and closed by rotating 90 degrees. Moreover, due to the approximately equal force of the medium on both sides of the shaft, the torque is opposite, resulting in a smaller opening and closing torque.

1. The valve body material should be made of PPH, RPP, PE, PVDF, CPVC, UPVC raw materials, and the sealing seat should be made of EPDM or FPM.

2. The valve body and pipeline are connected by flange clamping, and the connection standards can comply with DIN, GB, ASTM, JIS and other standards, so as to achieve unified standard requirements for the overall pipeline system.

3. The design and testing of the valve strictly comply with Q/ZBT02-2004.
