Q641PPL

The closure of the ball valve is a ball, the ball around the center line of the body to achieve the opening and closing of a valve. Ball valve in the pipeline is mainly used to do the cutting, distribution and change the direction of the flow of media. Wide ball valve is widely used in recent years, a new type of valve, the general level of the installation of the valve. Pneumatic ball valve is equipped with pneumatic actuator. Pneumatic actuator execution speed is relatively fast, the fastest switching speed of 0.05 seconds / time, so it is often called the fast cut off valve. Pneumatic ball valve is usually equipped with various accessories such as solenoid valves, air FRL limit switch, positioners, control box, in order to achieve local control and remote centralized control, the control room can control valve switch, do not need to run to the site or zone of high altitude and dangerous to manual control, to a great extent to save human resources and time and safety. Pneumatic ball valve specific categories: stainless steel pneumatic ball valve, pneumatic ball valve, sanitary pneumatic ball valve, carbon steel pneumatic ball valve, two pneumatic valve, three pneumatic valve, four pneumatic valve.
