Water Treatment Systems
Control valves are widely used in raw water treatment, filtration systems, reverse osmosis (RO) equipment, chemical dosing systems, and wastewater treatment facilities to precisely control flow, pressure, and liquid levels, ensuring stable and efficient operation throughout the entire water treatment process.
HVAC Systems
In chilled water systems, cooling water circulation systems, AHU (Air Handling Units), FCU (Fan Coil Units), and heat exchange equipment, control valves are used to automatically regulate flow and temperature, improving energy efficiency and maintaining a stable indoor environment.
Oil & Gas Industry
Used in oil and gas transmission pipelines, storage tank systems, separation equipment, compressor stations, and refining and petrochemical facilities, control valves enable flow regulation, pressure control, and process automation, ensuring the safe and stable operation of the system.
Chemical Processing Plants
In reactor inlet and outlet piping, chemical medium transfer systems, mixing equipment, and process control piping, control valves are used to precisely regulate fluid parameters, improving production efficiency and process stability.
Power Generation Facilities
Widely used in boiler feedwater systems, steam delivery piping, cooling water circulation systems, and steam turbine auxiliary equipment, control valves ensure the efficient operation of power generation equipment through precise control of flow and pressure.

What is the difference between a Control Valve and a Shut-Off Valve?
Control valves are primarily used for continuously regulating fluid parameters, while shut-off valves are primarily used to fully open or close pipelines. Control valves emphasize control accuracy, while shut-off valves emphasize isolation.
What control signals are supported?
Common control signals include 4–20 mA, 0–10 V, the HART communication protocol, and pneumatic control signals, depending on the requirements of the actuator and control system.
How important is valve sizing for Control Valves?
Valve selection and Cv value calculation are critical. Oversizing can lead to unstable control, while undersizing can restrict flow and affect system performance.
How often should a control valve be maintained?
It is recommended to periodically inspect the actuator, seals, valve plug, and control system. Proper maintenance can effectively extend the valve’s service life and maintain control accuracy.
What materials are available for control valves?
Common materials include ductile iron, carbon steel, 304 stainless steel, 316 stainless steel, and special alloy materials, which can be selected based on the medium and operating conditions.
