Hydraulic Control Valve Series

Our hydraulic control valve series is designed for automatic pressure regulation, water-level control, flow control, pump protection, and backflow prevention in municipal water supply, building services, irrigation, fire protection, water treatment, and industrial water systems. The range includes remote control float valves, pressure reducing valves, pressure relief and sustaining valves, slow-closing check valves, flow control valves, pump control valves, differential pressure bypass valves, solenoid control valves, and more. Operated by pipeline pressure through a pilot control system, these valves provide stable and responsive control without requiring complex external power equipment. Different body materials, sizes, pressure ratings, pilot arrangements, and control functions are available to meet various pipeline and project requirements.

Key Features & Advantages

● Automatic hydraulic control: Uses pipeline pressure and a pilot control system to regulate valve opening and closing.
● Multiple control functions: Supports pressure reduction, pressure sustaining, water-level control, flow regulation, pump protection, backflow prevention, and other system requirements.
● Stable system operation: Helps maintain the required pressure, flow, or liquid level under changing pipeline conditions.
● Reliable diaphragm-actuated design: Provides smooth valve movement and responsive control under suitable operating conditions.
● Adjustable control settings: Pilot valves can be adjusted according to the required pressure, flow, or operating sequence.
● Wide application range: Suitable for municipal water networks, buildings, irrigation, fire protection, water treatment, and industrial water systems.
● Flexible configuration: Body material, pressure rating, connection standard, pilot circuit, and accessories can be selected according to project requirements.
● Convenient inspection and maintenance: The modular pilot system and serviceable main-valve structure simplify commissioning and routine maintenance.

Valve sizing and pilot configuration should be selected according to the medium, inlet and outlet pressure, flow rate, operating sequence, installation conditions, and required control function. Special sizes, pressure ratings, materials, coatings, accessories, and control requirements can be discussed with the factory
