Double Block and Bleed Ball Valves is a ball valve with a pneumatic actuator, the execution speed of the pneumatic actuator is relatively fast, the fastest switching speed of 0.05 seconds/time, so it is usually called pneumatic fast cut ball valve. Pneumatic ball valves are usually configured with various accessories, such as solenoid valves, air source processing triplexes, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control, in the control room can control the valve switch, do not need to go to the scene or high altitude and dangerous to bring manual control, to a large extent, saving human resources and time and safety
