The flow control valve, also known as the 400X flow control valve, is a multi-functional valve that uses a high-precision pilot method to control the flow. It is suitable for pipelines where the water distribution pipe needs to control the flow and pressure. Keep the predetermined flow unchanged, limit the excessive flow to a predetermined value, and appropriately reduce the upstream high pressure. Even if the pressure upstream of the main valve changes, it will not affect Flow downstream of the main valve.

product features

  • The 400X flow control valve is mainly composed of a main valve, a flow regulating valve, a needle valve, a small ball valve, a micro pressure gauge, etc. to form a hydraulic control takeover system. It uses the automatic operation of water conservancy to control and adjust the opening of the main valve, so that the flow through the main valve remains unchanged.
  • This product utilizes a water conservancy control valve and does not require other devices and energy. It is easy to maintain and has stable flow control capability. It is widely used in high-rise buildings, domestic water supply pipe network systems, and urban water supply pipe network projects.
