Pneumatic control valve

product manual:

        Overview

        The pneumatic film double-seat regulating valve adopts a double-guide structure and is equipped with a multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. It is widely used to accurately control the process parameters of gas, liquid, steam and other media such as pressure, flow, temperature, and liquid level to maintain a given value. It is especially suitable for occasions with large pressure difference, large allowable leakage and not very clean media.

        This series of products has many varieties such as standard type, bellows sealed type, jacket heat preservation type. The nominal pressure grade of the product is PN16, 40, 64; the valve body diameter ranges from DN25 to 400. The applicable fluid temperature has various grades in the range of -250℃～+560℃. The leakage standard is Ⅲ and Ⅳ. The flow characteristic is linear or percentage. A variety of varieties and specifications are available.
