control valve

KNKE control valve is a type of valve used in industrial processes to regulate the flow of fluids (liquids or gases) through a pipeline or process equipment. Control valves are used to maintain a specific process variable, such as pressure, flow rate, temperature, level, or composition, by adjusting the valve opening in response to a control signal from a process controller.

Control valves come in various types, mainly includes electric regulating valve, pneumatic regulating valve and self-operated regulating valve. They are usually equipped with a pneumatic, hydraulic, or electric actuator, which can move the valve stem to open or close the valve, or to adjust the valve opening to a specific position.

Control valves are an essential component of many industrial processes, including oil and gas production, chemical and petrochemical manufacturing, power generation, and water treatment. They play a critical role in ensuring process safety, product quality, and environmental protection.

KNKE control valve pressure range is 1.6-50Mpa; Temperature range: - 196 to 550 ℃; Control mode: electric, pneumatic, self-operated; Valve body material: cast iron, cast steel, stainless steel, plastic; Valve body structure: single-seat valve, sleeve valve, ball valve, butterfly valve, etc
