The seat seal inlayed in the groove of body
Butterfly valve structure single, small volume, easy to install, suitable for large diameter valves. Minimum opening and closing torque, small fluid resistance, flexible and labor-saving operation. Good sealing performance at low pressure, good regulating ability, when fully open, the effective flow area of the valve seat channel is larger and the fluid resistance is smaller. The sealing surface material is generally rubber and plastic, so the low-pressure sealing performance is good. At low pressure, a good seal can be achieved.
The drive forms are manual, worm gear drive, electric, pneumatic, which can realize remote control and automatic operation. The disadvantages of butterfly valves are as follows:
1. The operating pressure and working temperature range are small.
2. Poor sealing.
The relationship between the operating pressure and temperature of the plastic butterfly valve, with the increase of the operating temperature, the service life of the plastic valve will be shortened. In order to maintain the same service life, the operating pressure needs to be reduced.
