400X flow control valve uses a high accuracy pilot operated flow control and is suitable for flow and pressure on the upstream, keep the preset flow unchanged, limit an extra-big flow at a preset valve and properly lower the high pressure on the upstream, the flow at he downstream will not be effected even if the pressure of the main valve at the upstream varies. It changes the principle for a throttle valve to reduce the basin area purely mechanically or by way of using orifices and utilizes the related pilot valve to reduce the energy loss during throttling to the utmost extent and features sensitive control, safety, reliability, easy debugging and long duration.
