China Mnaufacturer& Supplier Pneumatic Internal Thread Ball Valve
Q611N Pneumatic high pressure ball valve is divided into three types: pneumatic high pressure flange ball valve, pneumatic high pressure welding ball valve, pneumatic high pressure internal thread ball valve. It is powered by compressed air, and the stem drives the spool to rotate 90 in the valve body to achieve a fully open and fully closed action. It can adopt intelligent control and positioning, matching with the electric valve positioner, input 4-20madc signal and 0.4 ~ 0.7mpa air source to control the operation, can realize the adjustment of pressure, flow, temperature, liquid level and other parameters. Pneumatic high-pressure ball valve according to its sealing performance is divided into metal seal and soft seal. Pneumatic high-pressure ball valve has advantages: compact structure, small size, reliable operation, good sealing, easy maintenance, easy installation, strong adaptability. Pneumatic high-pressure ball valve is particularly suitable for medium is viscous, containing particles, fiber properties of the occasion. Pneumatic high-pressure ball valves are widely used in the automatic control system of petroleum, chemical industry, teaching equipment, light industry, high-pressure equipment, pharmacy, papermaking and other industries.

The Features of Pneumatic Actuators
The new series of pneumatic actuators, double acting and single acting (spring reset), thallium rack transmission, safe and reliable: large diameter valve series AW pneumatic actuator fork type transmission, reasonable structure, large output torque, double acting and single acting.

1. Gear type double piston, large output torque, small volume.

2. The cylinder is made of aluminum alloy with light weight and beautiful appearance.

3. Manual operating mechanism can be installed at the top and bottom.

4. Rack type connection adjustable opening Angle, rated flow.

5. The actuator can choose live signal feedback instruction and various accessories to realize automatic operation.

6. IS05211 standard connection provides convenience for product installation and replacement.

7. Both ends of the adjusting screw can make standard products at 0 degrees and 90 degrees have a + 4 ° adjustable range, precision to ensure synchronization with the valve.
