GB Butterfly valves's simple information
1) Compact and simple, easy to disassemble and repair, and install the actuator in a comfortable position
2) The flow characteristics tend to be straight and the scheduling performance is good.
3) The structure is simple, compact, the operating torque is small, and the 90 degree reversal opens quickly.
4) The connection between the butterfly valve disc plate and the valve stem adopts a pinless structure, which overcomes the possible internal leakage dew point.
5) The outer circumference of the disc is spherical, which improves the sealing performance and prolongs the service life of the butterfly valve. It still maintains zero leakage when the pressure is opened and closed more than 50,000 times.
6) The seal can be replaced, and the cut seal is firmly secured to the two-way seal.
7) The disc can be sprayed with a coating such as nylon or polytetrafluoroethylene.
8) The butterfly valve can be planned as a flange connection and a clamp connection
9) The drive mode can be selected manually, electric or Pneumatic.
