FLOW CONTROL VALVE EN400X
A. FLOW CONTROL VALVE Structure and Purpose
EN400X Flow Control Valve is uses for its high accuracy pilot operated flow control and is suitable for flow and pressure control of the pipeline to keep the flow preset unchanged, limit an extra-big flow at the preset value and properly lower the high pressure on the upstream, the flow at the downstream will not be affected by the pressure changing of the main valve at the upstream. It changes the principle of a throttle valve to reduce the basin area purely mechanically or by way of using orifices and utilizing the related pilot valve to reduce the energy loss during throttling to the utmost extent. And it features by sensitive control, safety, reliability, easy debugging and long duration.
