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.
