Hydraulic Control Valves, Ductile Iron Diaphragm Type Flow Control Valve

Product Description

Structure And Purpose:

400X 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

Purpose:

This valve is set on the water distribution pipeline where flow control is required to keep the preset flow unchanged,limit an excessive flow within a preset value and reduce the upstream high pressure to a downstream low one,thus making the valve downstream flow uninfluenced,even if the main valve upstream pressure varies.
bility, easy debugging and long duration

Characteristics:

Easy installation and use,no complicated electric sensing mechanism with the control portion,uneasy to be failed ,easily set table,automatically finishing adjustment,without need of manmade operation or other power source.

Principle:

The pilot valve of this valve gets the pressure difference signal from the orifice to control open-close of the main valve.when the pipeline flow is bigger than the set one,the openness of the main valve will become smaller to have the flow reset to the original set one and the disc stable without moving.
