Pneumatic high-pressure ball valves Q641N/Q647N/Q611N VF--QCC-Q193-CU Customized Customize

The pneumatic high-pressure ball valve is powered by compressed air. The valve stem drives the valve core to rotate 90° inside the valve body, enabling fully open and fully closed actions. The pneumatic high-pressure ball valve is composed of a pneumatic piston actuator and a high-pressure ball valve. It can be equipped with a valve positioner and input control signals (4-20mADC or 1-5VDC) as an air source to control its operation. It can also be equipped with a travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7MPa air source to achieve on-off operation, and send out two pairs of passive contact signals to indicate the opening and closing of the valve. Pneumatic high-pressure ball valves are widely used in industrial automatic control systems such as petroleum, chemical engineering, light industry, high-pressure equipment, pharmaceuticals, and papermaking, for remote centralized control or local control.
