Q671F Pneumatic wafer thin ball valve introductuon
Q671F Pneumatic wafer thin ball valve is a new generation of ultra-short flange pitch ball valve developed by the introduction of Italian technology for domestic design, Q671F Pneumatic wafer thin ball valve is composed of single (double) action piston pneumatic actuator and ultra-thin ball valve.Q671F Pneumatic wafer thin ball valve can be equipped with valve positioner input control signal (4-20madc or 1-5vdc) air source can control operation.Q671F Pneumatic wafer thin ball valve Can also be equipped with stroke limit switch, solenoid valve, pressure reducing valve and 0.4 ~ 0.7mpa air source to achieve switching operation, and send out two pairs of passive contact signal indicating the switch valve.

Q671F Pneumatic wafer thin ball valve ball core channel shape rectangular, v-shaped and o-shaped.This series of Q671F Pneumatic wafer thin ball valve have the characteristics of compact structure, small volume, light weight and convenient installation.Therefore, Q671F Pneumatic wafer thin ball valve is widely used in the fields of petroleum, chemical industry, metallurgy, power plant, light industry, and so on, oil, water, gas and pulp or fiber fluid for automatic adjustment or cut off control.
