Features
400X Rate-of-Flow Control Valves 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.
400X Rate-of-Flow Control Valves is a kind of multifunctional valve, using advanced pilot method to control flow
rate of fluid. It is used in the pipeline where flow rate and pressure need to keep stable and keep the flow
rate stable and limit the over large flow rate to the preset flow rate in the downstream do not change. This
kind of is different general throttle valve that reduces flow area to control flow rate, it uses related pilot
valve is different general throttle valve that reduce flow area to control flow rate, it uses related pilot
valve to reduce energy loss when throttling. In emergency vt-400X flow control valve can shut off the fluid and
avoid loss. Its sensibility is very high and it is very safe and reliable and it's life is very long and it is
very easy to maintain.
