Oxygen Control Valve

 The main difference between the oxygen control valve and the ordinary control valve is: one more production process requires oil-free treatment. Generally, carbon tetrachloride cleaning can achieve the purpose of degreasing and oil-free.The flow control valve for oxygen adopts a top-oriented structure and is equipped with a multi-spring actuator. The oxygen flow control valve has the advantages during the use of flow control valve such as compact structure, lightweight, sensitive action, S streamline flow channel, small pressure drop loss, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly.

UTMOST valve OEM, a leading China valve manufacturer and China valve supplier with valve factory, is providing high-performance types of industrial valves for our customers.
