● The butterfly valve is double flange type body design, with heavy strong strength.
● The soft molded seat is bonded to body, ensure sealing at full rated pressure.
● Overall vulcanizated sealing performance is more stable, can revent seat deformation and dislocation under the pressure.
● Connect between disc and stem, can be pinless spline type and split stem or with pin type.
● High Cv, lower head loss, longer lifetime with low operating torques.
● Operator can be manual hand lever, worm gear, electric actautor or penumatic actuator.
● Excellent design and long service life.
