China Oxygen Control Valve

 China Oxygen Control Valve

The main difference between the oxygen flow 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. As a control valve china factory, UTMOST oxygen flow control valve has the advantages during the use 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. Please feel free to contact our control valve manufacturers in china for more information.
