Pneumatic Single Seat Globe Control Valve Product Information

Pneumatic single seat globe control valve is top guide structure, which is equipped with pneumatic diaphragm actuator. Single seat globe control valve flow port is s-shaped, which is featured with little pressure drop, big valve cavity, accurate flow characteristic and easy assembly & disassembly. This type of single seat regulating valve is used widely to control accurately the gas or liquids pressure, flow, temperature and level, especially applicable to the working condition of allowing little and differential pressure before and after the valve is not big. Flowspec Luokai can manufacture and supply the pneumatic single seat globe control valve with leakage class ANSI B16.104 class IV, class VI, class II. Contact us today.
