Fixed pneumatic hard seal ball valve Q647Y images

Pneumatic hard seal ball valve Q647Y fixed structure, sealing deputy ( The pneumatic valve seat sealing surface and sphere seal face) Material matching for metal to metal. By assembling AW pneumatic actuator fork type transmission, reasonable structure, large output torque, a double-acting and single acting, but by electromagnetic pneumatic valve control, realize the switch of pneumatic ball valve, also can realize intelligent control, quickly turned on or off line, can effectively control and management of network.





pneumatic hard seal ball valve with electric pneumatic valve positioner, input 4 ~ 20 madc signal and 0. 4 to 0. 7 mpa air can control operation, realize the parameters such as pressure, flow, temperature, liquid level adjustment. Also travel limit switch, solenoid pneumatic valve, relief valve, and 0. 4 - 0. 7 mpa gas source switch operation can be realized, and sent out two indicates a pneumatic valve on the passive contact signal switch.
