Proportional Integral Control Valve

We are offering proportional integral control valve.
Purpose
proportion integral regulating valve zlva-3000 series actuator is straight route actuator, could be matched with zlvg-7000 series valve body, as to achieve regulation function on pipe medium flow. Widely applied to air condition and heating system, could be also matched with different connector and other valves.
Specification on type：
zlva-3000：floating type, built-in 24vac two-way reversible motor, accept switch type control signal, supply incremental control.
Zlva-3100：floating type, built-in 220vac two-way reversible motor, accept switch type control signal, supply incremental control.
Zlva-3102：intellectual type, accept and feedback 0-10v or 4-20ma control signal, supply proportion control
characteristics：
◆ low ac pressure synchronous reversible motor, with function of hysteresis clutch protection.
◆ adopt small size route limit switch.
◆ inflaming retardant abs engineering plastic cover
◆ valve position indicator
◆ suitable for straight route regulating valve under 20mm
◆ no noise, with big output torque.
◆ easy installation
specification on intellectual debugging：
◆ long press key ①，“led1” light turns on, press ① again,“led1” light flashes and enter into route automatic calibrating procedure;
◆ long press ② switch to positive reverse rotation. “led2” light means positive rotation, “led2” means 4－20ma current;
◆ long press ③ switch to pressure-current input. “led3” is 0－10vpressure, “led3” is 4－20ma current;
◆ completion of wiring shall be indicated according to route, as to ensure valve complete accurate action according to given signal.
