China Jingjia Valve (Group) Co.

SJ400X flow control valve

The valve adopts high-precision pilot flow control, which is suitable for controlling flow and pressure pipelines, keeping the predetermined flow unchanged, limiting the excessive flow to a predetermined value, and appropriately reducing the upstream high pressure, even if the pressure upstream of the main valve changes It will not affect the downstream flow. This valve changes the principle of using a conventional throttling valve and using a hole puller or purely mechanically to reduce the area of ​​the watershed. It uses the relevant pilot valve to minimize the loss of energy during the throttling process. The control is sensitive, safe and reliable, the debugging is simple, and the service life is long.

This valve uses a high accuracy pilot operated flow control and is suitable for flow and pressure pipeline control to keep the preset flow unchanged. 1 limit an extra-big flow at a preset value and properly lower the high pressure on the upstream. the flow at the downstream will not be affected even if the pres-sure of the main valve at the upstream varies. 1t 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.
