Product Features
Butterfly valve is mainly consisted of body, stem, disc, seat and driver (lever, gearbox,pneumatic and electric Actuator) and so on. On-off and controlling flow of valve are made by turning stem and disc together. Features as following:
1.Simple and compact construction, small in size and light in weight. Easy transportation and installation.
2.Quick 90°on-off operation, minimized operating torque, energy saving.
3. Sealing capability well, long service life, with no leakage under pressure test.
4.Wide selection of materials applicable for various mediums.
5.Flow curve tending to straight line. Excellent regulation performance.
