Structural characteristics of 
 1, the valve by the valve body, driving device, the clamping device and other components. 
 2, the valve body using a three-point structure, compact, and the overall rigidity, weight. 
 3, the valve body, valve plate sealing pair made of a flexible stainless steel and rubber seal pair, reliable sealing, seal with Viton, high temperature, long service life. 4, the clamping mechanism of the screw-nut style clamp, loosen and prompt action, self-locking. 
 5, explosion proof motors, whether indoors or outdoors, can ensure that the valves safe and reliable transportation action. 
 Manual operation of the blind plate valve field, can also be long-range sequence. 
 7, the blind plate valve can also be individually designed electrical control box operation control device, the machine factory unworthy of the electrical control box, users For separate. 
 Action principle 
 A valve open to valve closed 
 Clamping action of the motor, drive the screw for counterclockwise rotation of the body release the place (indicator) action of the drive motor to drive the gate for counter-clockwise rotation in place, the gate closed in place (indicator), the clamping motor action, driving the screw for clockwise rotation, the body is clamped in place (indicator) to complete the whole process of the valve from open to closed. 
 2, the valve to open by the close of 
 Clamping action of the motor, drive the screw for counter-clockwise rotation, body loosen place (the indicator light shows) drive motor action, clockwise rotation to drive the gate, the gate to open branch, (the indicator) to complete the valve from the closure of the open process.
