Electric flow control valve Feature

1.Electric flow control valve is used for flow control system,electric flow control valve adopts the top guide structure, compact structure, S streamlined fluid path, large flow, small pressure differential loss, wide adjustable range and accurate flow control.

2.Electric flow control valve is single seat design for low pressure differnece , cage guided design for high pressure difference, spool guiding part, characterized with excellent anti-vibration performance

3.The intelligent control module of electric flow control valve is built into the electric actuator,without external positioner
