Use Scenarios
Water Flow Stabilization in High-Rise Building Plumbing
In urban high-rise plumbing systems, maintaining constant water pressure and flow is critical to support residential and commercial occupants. The 400X Flow Control Valve functions as a hydraulic control valve that automatically compensates for variations in pressure caused by changes in demand or elevation changes within the building. Its integration with existing pipeline assemblies enables continuous regulation without electrical power, ensuring compliance with building codes and operational safety standards. The valve’s customizable sizing allows for seamless installation in diverse piping configurations, optimizing the building’s water distribution reliability and simplifying maintenance protocols for facility management teams.
Municipal Water Network Pressure Regulation
Municipal water supply networks demand valves capable of stabilizing flow under fluctuating consumption rates and variable source pressures. The 400X, as a custom flow control valve, supports hydraulic self-control to maintain set flow thresholds, reducing pressure surges that can damage infrastructure or compromise service quality. It integrates easily into water distribution nodes and pumping stations, where real-time pressure data from the built-in gauge aids in system monitoring and operational adjustments. This valve’s robust design and precise regulation fulfill the rigorous standards faced by wholesale flow control valve buyers focused on public utility performance, reducing water loss and enhancing supply resilience.

Product profile
The 400X flow control valve consists of a main valve, a flow regulating valve, a needle valve, a pilot valve, a ball valve, amicro-filter and a pressure gauge. By adjusting the opening of the main valve, the fiow through the main valve remainsunchanged. Flow control valve uses hydraulic self-control, does not need other devices and energy, easy maintenance, flowconitrol is siable. Fiow conirol valve producis are widely used in high-ise buildinas, living areas and other water supply networksystems and urban water supply projects.
Working principle
When the valve is fed water from the inlet end, the water into the main valve control room through the needle valve, and flowsout of the main valve control room through the pilot valve. At this time, the main valve is in a fuly open state. The main valve canbe set at a certain opening by setting the fow control valve above the main valve. Adiusting the opening of the needle valve ancadiusting the spring pressure of the pilot valve can keep the opening of the main valve at the set value. When the pressurechanges, the pilot valve can be automatically adjusted to keep the flow constant.
