Pneumatic Cage Guided Globe Control Valve Product Information
Pneumatic cage guided globe control valve is one type of pressure balance regulating valve with pneumatic diaphragm actuator, whose valve flow port is s-shaped linear type. It has a contra-vane to improve the fluids flow balance arounds the cage. Cage type globe control valve is normally used to control high pressure fluids, because it’s featured with small pressure drop, big flow capacity, wide adjustable range and high flow characteristic accuracy. Its actuator can be pneumatic diaphragm type or electronic electric actuator. Flowspec Luokai can manufacture and supply the Pneumatic cage guided globe control valve with sizes of 1-1/4″ ~ 8″ (DN32~DN200mm). Contact us today. Get the better prices. 30 years of experience. Great after-sales service.
