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.

备注 Note:1、最大允许压差不超过最大工作压力
The maximum allowable differential pressure does not exceed the maximum pressure
2、同一格内,/前方数字表示阀常开允许压差,后方数字表示阀全关允许压差。
The number in the front of ‘/ ‘indicates the allowable differential pressure for valv e totally opened, the rear numerals indicates the allowable differential pressure for valve
totally closed.
3、以上允许压差均采用标准执行机构,当压差不满足时,也可增大执行机构。
The above allowable differential pressure under standard actuator, If the differential pressure is not enough then can use enlarged actuator.
