Structural Characteristics And Working Principle
1, The output force of the actuator through the valve stem acting on the main spool, the design of a certain angle, the main spool, into the horizontal direction of the left and right, and through the spool, sealed disc pressed two seats, the formation of double Seal seal, seal does not leak, torque is small, the switch valve seal surface without friction, fundamentally solve the valve plug in the valve body stuck or not open the ills.
2, Pneumatic actuator adopts piston mechanism and solenoid valve as the switching element of the intake and exhaust of the upper and lower parts of the control cylinder to control the vertical displacement of the opening and closing parts to control the opening and closing of the valve,
3, Equipped with a return device for sending the valve open signal, solenoid valve to achieve long-range control, centralized control, automatic control, and on-site operation.
5, The valve open and close the status of the field instructions, the coat of the extension of the display bar of the rise and fall, marking the valve is fully open (the extension of the indicator rod is located in the highest position), the valve is fully closed (extension indicator rod at the lowest position).
6, With spring reset single acting pneumatic device or air tank series to ensure that the power supply, gas source when the automatic switch failure, safe, reliable, speed, environmental protection, energy saving.
