Pneumatic ball valve consists of two main parts: ball valve and pneumatic actuator. It usually needs to be equipped with solenoid valve, air source handling triple parts, limit switch, positioner and other accessories to achieve remote control and local control. In the control room, it can control the opening and closing of the valve without running to the scene or high altitude and dangerous areas to control manually, which saves manpower to a great extent. Resources and time and security.
1. Pneumatic ball valves are classified into stainless steel pneumatic ball valves, plastic pneumatic ball valves, sanitary grade pneumatic ball valves, carbon steel pneumatic ball valves and cast iron pneumatic ball valves.
2. Flange pneumatic ball valves, threaded pneumatic ball valves, welded pneumatic ball valves, clamp pneumatic ball valves, low pressure pneumatic ball valves, medium pressure pneumatic ball valves, high pressure pneumatic ball valves, direct pneumatic ball valves according to channel position, three pneumatic ball valves, right angle pneumatic ball valves
3. The sphere of the floating ball pneumatic ball valve is floating according to the characteristics of the ball. Under the action of medium pressure, the sphere can produce a certain displacement and press tightly on the sealing surface of the outlet to ensure the sealing of the outlet.
A. Fixed balls: The balls of pneumatic ball valves are fixed and do not move after being pressed. Fixed ball valves are equipped with floating seats. After medium pressure, the seats move, so that the sealing ring is pressed on the ball to ensure sealing.
B. Elastic balls: The balls of pneumatic ball valves are elastic. Elastic balls are made by opening an elastic groove at the lower end of the inner wall of the balls to obtain elasticity.
