First, F9L43X chain electric fan-shaped blind valve Features:
F9L43X chain type electric fan-shaped blind valve, also known as electric fan-shaped glasses valve, electric flap valve, mainly by the left valve body, the right valve body, fan-shaped gate, stainless steel bellows, electric drive, electric clamping devices and other components. Body with three-point locking fan-shaped gate structure. Sealing parts of stainless steel and rubber seals, sealing performance, long service life, the seal is located on the gate, easy to replace the seal for maintenance. Electric operation, work smoothly, start flexible and reliable action. Clamping mechanism using screw nut clamping, self-locking is good. Electric fan valve with stainless steel bellows, with flexibility, long service life and so on.
