Description
Flow control valves are used in pipelines where the distribution pipe needs to control the flow and pressure, keeping the predetermined flow constant, limiting the excessive flow to a predetermined value, and reducing the upstream high pressure appropriately, even if the pressure upstream of the main valve changes, it will not affect the flow downstream of the main valve. In case of emergency, the ACV400 flow control valve can cut off the flow to avoid losses. It has high control sensitivity, safety & reliability, easy commissioning, and long service life.
Installation of Flow Control Valve
Features and Application ACV400
The ACV400 flow control valves use hydraulic self-control, no other devices and energy, easy maintenance, and stable flow control. This series of control valve products are widely used in high buildings, domestic areas, and other water supply pipeline systems and city water supply projects.
Maintenance Instructions For Flow Control Valve
The hydraulic control valve is a self-lubricating valve body using water, without the need for additional oil lubrication, if you experience damage to the internal parts of the main valve, according to the following instructions for disassembly.
- Close the gate valves upstream and downstream of the main valve.
- Loosen the screws of the piping connector on the main valve cover to relieve the pressure inside the valve.
- Remove all screws, including the necessary copper tubing and nuts in the control line.
- Remove the cover and spring.
- Remove the plug, diaphragm (piston), etc. Please be careful and do not damage the diaphragm.
- Check if the diaphragm and gasket are damaged, if not, please do not disassemble the internal parts.
- If you find that the diaphragm or gasket is damaged, please loosen the nut on the plug, disassemble the diaphragm or gasket piece by piece, and then replace it with a new one.
- Check all detail whether there is damage to the valve seat and plug inside the main valve, and if there is other debris in the main valve, clean it all up.
- Assembly the replaced parts in reverse order and install the main valve, paying attention to the valve must not being stuck.
- Please refer to the installation operation notes to reuse.
