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.
信号球阀的适用介质是水、气、油品等,适用温度是-23~121℃
阀体采用整体式结构。通过精密的加工和装配,球芯由一端装入后,旋紧压环,使两软密封阀座与球芯保持良好的接触和密封。同时,压环内垫也实现良好的密封,使阀门工作的泄漏为零。由于公司采用整体式结构的阀体,所以该阀实现了超短法兰距,整机重量大大降低,仅为同类普通球阀的50%左右。
