          Dome valve
          PRODUCT DETAILS£º


          Structural Features

          1 Its sealing surface adopt silicone rubber inflatable seal to guarantee zero leakage

          2 The valve adopts double electromagnetic control and dedicated solenoid valve are used for control of both actions

          Working Principle

          When the valve is close , the dedicated solenoid valve for the pneumatic actuator will act ;the pneumatic actuator will drive the  ball to  rotate to the closing position through the valve stem , triggering the changeover push  rod ;and then the gasket ring will be inflated to compress the ball surface to produce a seal .When the  valve is open , the dedicated solenoid valve for the  gasket ring will exhaust rapidly and disengage itself from the ball surface to a free state ; then the dedicated solenoid for the pneumatic actuator will act ,and the cylinder will drive the  ball to rotate to open position
