Product Overview
The pneumatic thin film high-temperature control valve is composed of a multi spring pneumatic thin film actuator and a low flow resistance high-temperature regulating valve body. The multi spring actuator has low height, light weight, and simple equipment. The valve body flow channel is S streamline, with the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient maintenance, etc., which can be used in harsh working conditions. Equipped with electric pneumatic valve positioning or pneumatic valve positioner, it can achieve automatic adjustment and control of the fluid medium in the process pipeline. Widely used for precise control of process parameters for gases, liquids, steam and other media, such as pressure, flow rate, temperature, liquid level, etc., to maintain the given values. Especially suitable for situations where small leakage is allowed, the pressure difference between the front and rear of the valve is not large, and the temperature is high.
