The electric ball (sphere) around the vertical channel axis 90 º valve by the electronic transition back to the rotary electric actuator and the structure of O-type valve is a rotary type high-performance adjustment or switching valves, and to accept(DCS, PLC system) instrument the source of the current signal or voltage signal input and output of industrial automation and control, can adjust the proportion of the fluid medium in the process piping or two switch control to achieve the flow of the fluid medium, pressure, temperatureautomatic control of liquid level and other parameters.
Features
A. Electric ball valve fluid resistance is small, and all valves in the fluid path of least resistance kind of power, AC220V, AC380V or DC24V power supply voltage to accept (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal, can control the operation, the output of the rotary torque to rotate the sphere 0 ~ 90 º will be able to complete the opening and closing movement or adjust the action.
Two. Ball core channel is smooth, easy deposition medium, can be pipelined through ball. Simple structure, light weight, good sealing performance. Especially suitable for situations requiring zero leakage rate.
3. HL type 3810R type, PSQ type rotary electric actuator for fully electronic drive unit of the O type ball valve, mechanical and electrical integration of structural design, position feedback of the machine servo operation and opening signal, position indicator, manual operation functions, functional, reliable performance, simple connection, as the power supply voltage AC220V or AC380V directly accept the signal of a unified standard (4-20mA DC,0-10mA DC or 1-5V DC, 0-10V DC)
Into this with the input signal corresponding to the displacement and angular displacement (0 ~ 90 º) movement to change the rotation of the ball core opening, and a certain input signal corresponds to the opening of a certain position to achieve proportional control action. (Two switch-to AC220V or AC380V supply voltage for power, motor reversing switch action, and at the same time the output of the switch valve position indication signal). Is a high precision, high-performance, high reliability products
