In modern water supply, drainage, industrial fluid transmission, and municipal hydraulic engineering systems, stable and safe water flow operation relies heavily on professional hydraulic control valves. Hydraulic valves feature simple structure, high automaticity, strong durability, and convenient maintenance. According to different functional attributes and application scenarios, mainstream hydraulic control valves are divided into six core types, including 100X ball float valve, 200X pressure reduce valve, 300X slow-closing check valve, 400X flow control valve, 500X pressure relief valve, and multi functional water pump control valve. The detailed introduction of each type is as follows:

1. 100X Floating Ball Valve

The 100X floating ball valve is a dedicated automatic water level control hydraulic valve, mainly used for automatic water inflow control of water tanks, water pools, and reservoirs. Relying on the buoyancy of the floating ball and the pressure difference of the pipeline water flow, the valve can automatically open and close without manual intervention. When the water level of the water tank drops to the set low level, the floating ball falls, driving the valve to open and start water inflow; when the water level rises to the preset high level, the floating ball rises with the water surface, pushing the valve to close automatically to stop water supply, realizing full-automatic water level constant control.

This water level control valve has the advantages of sensitive action, stable performance, and no water leakage. It effectively avoids water overflow and dry tank problems, saves water resources, and reduces manual management costs. It is widely suitable for water level control of domestic water tanks, industrial water storage pools, cooling water pools, and small and medium-sized water conservancy storage facilities.

2. 200X Pressure Reducing Valve

The 200X pressure reducing valve is an automatic pressure regulation valve designed for pipeline water pressure stabilization. This water pressure control valve’s core function is to reduce the unstable high-pressure water flow at the upstream of the pipeline to the stable low-pressure state required by downstream equipment and maintain the downstream pressure constant for a long time. The reducing pressure valve uses the self-energy of the water medium to drive the internal diaphragm and spring adjustment mechanism, realizing stepless pressure regulation and automatic pressure compensation, which can adapt to the fluctuation of upstream water pressure and flow.

Different from ordinary pressure reducing valves, the 200X pressure control valve model features high pressure regulation accuracy, strong anti-fluctuation ability, and stable outlet pressure. This reduce pressure valve can effectively protect downstream pipelines, valves, water meters, and terminal water equipment from damage caused by excessive water pressure. It is commonly used in high-rise building water supply, municipal pipe network pressure regulation, industrial circulating water systems, and equipment cooling water pipelines.

3. 300X Slow-closing Check Valve

The 300X slow-closing check valve is a special pipeline protection valve integrating one-way flow control and slow closing buffer function. Its main function is to prevent water flow backflow and eliminate pipeline water hammer damage. In the water supply system, when the water pump stops running or the pipeline pressure suddenly changes, the water flow is prone to reverse flow and form strong water hammer impact, which will cause pipeline vibration, interface damage, and even pump body failure.

The 300X micro resistance slow closed valve adopts a unique slow closing structural design. It can quickly cut off the reverse water flow in the initial stage of backflow, and slowly close the valve body in the later stage to buffer the pressure impact, avoiding the water hammer phenomenon caused by sudden valve closure. It has the dual advantages of anti-backflow and water hammer elimination, greatly improving the safety and stability of water pump and pipeline system operation. It is mostly installed at the outlet of water pumps in municipal water supply, industrial water delivery, and large circulation pipeline systems.

4. 400X Flow Control Valve

The 400X flow control valve is a professional hydraulic valve for precise flow limit and regulation, committed to controlling the pipeline water flow within a preset fixed value. For water supply pipelines with unstable flow and easy overload operation, this water flow regulator valve can automatically sense the upstream and downstream flow changes, adjust the valve opening in real time through the hydraulic control mechanism, and limit the excessive flow to the set standard range.

While realizing constant flow control, the 400X water flow control valve also has a certain pressure reduction and pressure stabilization effect, which can balance the flow distribution of branch pipelines and avoid partial pipeline overload operation. It effectively solves the problems of uneven water supply and excessive flow impact in complex pipe networks, ensuring the balanced and stable operation of the entire water supply system. This water control valve is widely used in building water supply branch pipes, industrial process water pipelines, and farmland irrigation pipe networks.

5. 500X Pressure Relief Valve

The 500X pressure relief valve, also known as pressure release and pressure stabilizing valve, is a key safety protection valve for overpressure prevention of water pipelines. When the pipeline water pressure is abnormally increased due to water pump start-stop, water flow impact, or pipe network blockage, exceeding the safe working pressure of the pipeline and equipment, the 500X water pressure regulators for rvs will automatically open the pressure relief channel to discharge excess water flow.

After the pipeline pressure returns to the normal preset range, the valve will automatically close and reset, maintaining the stable pressure of the pipe network. It can effectively prevent pipeline cracking, equipment damage, and system failure caused by overpressure, and provide reliable safety protection for high-pressure water supply systems. It is suitable for high-rise water supply, fire protection pipe networks, industrial high-pressure water delivery, and pressure container water systems.

6. Multifunctional Water Pump Control Valve

The multifunctional water pump control valve is an integrated intelligent hydraulic control valve specially developed for water pump outlet systems, which integrates multiple functions of electric valve, check valve, and water hammer eliminator. Different from single-function hydraulic valves, this valve adopts a double-chamber and double-valve disc structure, realizing integrated control of pump start-up buffering, operation stabilization, and shutdown protection.

During the water pump start-up stage, the valve opens slowly to avoid instantaneous current overload and water flow impact; during normal operation, it maintains stable flow and pressure transmission; when the water pump stops suddenly, This diaphragm type hammer check valve can realize quick anti-backflow and slow-closing pressure relief, completely eliminating start-stop water hammer and medium backflow phenomena. It replaces the traditional combined installation of multiple valves such as gate valve and check valve, simplifying the pipeline structure, reducing installation and maintenance costs, and greatly improving the operational reliability of the water pump water supply system. It is the preferred supporting valve for large and medium-sized water pumps in municipal water works, industrial water supply, and high-rise building water supply projects.

Summary

Each series of hydraulic control valves has independent functional positioning and application scenarios. From water level control, pressure regulation, flow limit to anti-backflow and overpressure protection, the six core types of hydraulic control valves form a complete fluid control system. All valves adopt self-hydraulic drive, featuring energy saving, environmental protection, stable performance, and low failure rate, which can meet the diversified control needs of various water conservancy and water supply pipeline systems, and are essential core equipment for ensuring the efficient and safe operation of modern fluid pipeline systems.
