when AW pneumatic actuator is used, the Torque of Gate Valve opening and closing should be defined, and then the standard value should be raised according to the liquid material applied. When selecting AW pneumatic actuators for steam or non-lubricated models, the torque between the opening and closing of the gate valve should be determined first, and then the standard value should be raised according to the fluid used in the gate valve. Raise 20% standard value for cleaning and moistening materials, 25% standard value for water vapor or non-moistened materials, 60% standard value for non-moistened dry gas materials; 100% increase in non-wetting particulate matter and particulate matter transported by vapor. A dual-or single-effect torque meter is then searched based on the pneumatic valve pressure until the precise electric actuator model specification. In the single-effect output torque meter, the least spring-yellow Torque is the Torque when the gate valve is closed, and the larger spring-yellow Torque is the Torque when the gate valve is opened. Functions and main uses of electric actuators and accessories 1. dual-effect electric actuators: two-position control for opening and closing gate valves. 2, single-effect electric actuator (Spring Yellow calibration) : In the power circuit, gas supply open or common failure, full automatic shut-off gate valve. Dual motor control relay: One solenoid is powered on when the gate valve open, the other solenoid is powered off when the gate valve, memory effect (can be shown flameproof) . 4, single motor control relay: Power Supply System when the gate valve open or closed, closed power when the gate valve closed or open (can show explosion-proof) . TRAVEL SWITCH TRANSPONDER: long-distance Transmission Gate Valve Open or closed parts of the data signal (can show flameproof) . Electrical positioner: Adjust the total mass flow of the gate valve according to the size of the current data signal (4-50mA)(flameproof type can be shown) . 7. PNEUMATIC POSITIONER: adjust the total mass flow of the gate valve according to the dimensions of standard pressure data signals (specification 0.02-0.1 MPA) . 8, electrical converter: The current data signal conversion 10,000 standard air pressure data signal, and pneumatic positioning instrument supporting facilities application (can be shown flameproof) . 9, PNEUMATIC VALVE TO SOLVE THREE PARTS: including air pressure reducing valve, filter device, pneumatic three parts, pneumatic valve regulator, cleaning, fitness exercise components from the moistening effect
