XHQ671 pneumatic valve is a new generation of ultra short flange ball valve, which is a new generation of ultra short flange ball valve with the introduction of Italy technology, and the shape of the ball core channel is rectangular, V and O. This product has the characteristics of compact structure, small volume, light weight, convenient installation, and can be widely used in petroleum, chemical, metallurgical, power, light industry and other fields of oil, water, gas, and pulp or fibrous fluid automatically adjust or cut off control.
XHQ671 pneumatic signal valve by the pneumatic double piston gear rack actuator and ultra short flange ball valve combination, the body part of the same as the "1" electric ball valve body. The pneumatic piston actuator is divided into two types, which are spring type and non spring type. Failure under the requirements of the valve fully open or closed when equipped with a spring type (by the spring to restore the tension reset), the failure of the requirements when the position, with no spring type. It is mainly composed of a cylinder, spring, piston, piston rod, cylinder head, output shaft, rack and other components. The two switch valve with electromagnetic valve and a stroke switch; proportional valve, with positioner.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
Signal ball valve is suitable for water, gas, oil and so on, the applicable temperature is -23 ~ 121
Valve body adopts integral structure. Through the processing and assembling precision of the ball by the end loaded, tighten the pressure ring, the two soft sealing valve seat and ball to maintain good contact and seal. At the same time, the pressure ring also achieve a good seal, so that the valve leakage is zero. Because the company uses the integral structure of the body, so the valve to achieve ultra short flange distance, the weight of the whole machine is greatly reduced, only about 50% of the same ordinary ball valve.
