Adjustment and control of pneumatic quick loading ball valve

Pneumatic quick loading ball valve pneumatic positioner, according to the pressure signal (standard 0.02-0.1MPa) of the size of the valve medium flow control.Ball valve is a valve with a circular channel of the ball as the opening and closing parts, the ball with the stem rotation to achieve the opening and closing action of the valve.The opening and closing element of the ball valve is a perforated ball that rotates around an axis perpendicular to the channel to open and close the channel.Ball valve is mainly used to cut off or connect the pipeline and equipment medium, can also be used for fluid regulation and control, ball valve fluid resistance is small, simple structure, small volume, light weight, tight and reliable, easy operation and maintenance, will not cause the erosion of the valve sealing surface, a wide range of application.Electrical converter: the current signal into air pressure signal, and pneumatic positioner matching use (can provide explosion-proof type).Air source treatment triplet: including air pressure reducing valve, filter, oil mist device, air source stability, cleaning, lubrication of moving parts.Manual operation: automatic control can manually operate the valve opening and closing under abnormal circumstances.

Pneumatic quick loading ball valve double acting actuator: control the opening and closing of the valve.Single-acting actuator (spring return) : automatically closes the valve when the circuit or gas circuit is cut off or there is a fault.When the power is single control solenoid valve: the valve open or close, when the power is close or open the valve (available with explosion-proof type) double control solenoid valve: a coil electricity when the valve opens, another coil electricity when the valve closed, with memory function (available with explosion-proof type) limit switch to reply: remote transmission and off valve position signal (available with explosion-proof type).Electrical positioner: according to the current signal (4-20mA) of the size of the valve medium flow control (explosion-proof type can be provided).
