Hydraulic Control Valve

Hydraulic Control Valve

Main Parameters

• Nominal Pressure: PN10~PN25

• Nominal Diameter: DN20~DN800

• Operating Temperature: 0℃~+80℃, custom high-temperature models up to 120℃

• Drive Method: Self-driven by water pressure, no electricity or air supply required

• Valve Body Material: Ductile iron, carbon steel, stainless steel, suitable for various pipelines

• Sealing Performance: Primarily soft seal, tight seal, no leakage at low pressure

Product Description

Structural Forms

 

1. Remote-controlled float valve: Automatically controls water levels in water tanks and towers, automatically replenishing and shutting off water supply.

2. Slow-closing check valve: Eliminates water hammer, prevents backflow, and protects pumps and piping systems.

3. Pressure reducing/stabilizing valve: Maintains constant downstream pressure, reduces and stabilizes pressure, and balances pressure differentials in the piping network.

 

Core Advantages

 

• Self-operated hydraulic drive, requiring no electricity or gas, energy-saving, safe, and easy to install.

• High functional integration, enabling multiple functions such as pressure stabilization, pressure reduction, pressure relief, check valve, and water level control.

• Smooth opening and closing, effectively suppressing water hammer impact and extending the service life of pipelines and equipment.

• Sturdy structure, low failure rate, requires no daily supervision, and simple maintenance.

• Large flow capacity, low flow resistance, significant cost-effectiveness for large-diameter pipes, suitable for large-scale piping networks.

 

Suitable Applications

 

• Municipal water supply and drainage: Urban water supply networks, waterworks, secondary water supply systems.

• Building Systems: Automatic water replenishment control for high-rise water supply, fire protection networks, and water tanks/towers.

• Industrial Circulation: Pressure stabilization and protection for factory cooling water, circulating water, and water supply/drainage pipelines.

• Hydraulic Pumping Stations: Backflow prevention, slow-closing noise reduction, and water hammer elimination protection at pump outlets.

• Industrial Park HVAC: Pressure reduction, stabilization, and pressure relief regulation for pipeline networks in large residential areas and industrial parks.

2. Bottom-opening discharge valve: Valve plate opens downwards, fast discharge flow rate, good self-cleaning effect, thorough unloading.

3. PTFE-lined discharge valve: The entire valve is lined with fluoroplastic, resistant to strong acids and alkalis, corrosion-resistant, specially designed for chemical corrosion environments.

Pressure Reducing Valve

Pressure Reducing Valve

Working Principle: Relying on the pressure of the medium itself + pressure difference sensed by a spring/diaphragm/piston:

1. High-pressure medium enters the valve;

2. The sensing element monitors the downstream pressure in real time;

3. High pressure → valve disc closes slightly, throttling and reducing pressure;

4. Low pressure → valve disc opens wider, replenishing and stabilizing pressure; Fully automatic adjustment, no external power required.
