ZSQRThe standard ball core of pn16-pn64 three-way O-type pneumatic ball valve has L-type three-way double port port port and T-type three-port port port. By changing the relative angle between the ball core and the pipe, different combination control can be realized for the three branch pipe fluid. The T-shaped duct can connect three orthogonal pipelines, or make two of them connect and cut off the other one. L-shaped channels can only connect two orthogonal pipes or switch directions. In other words, the T-shaped channel plays the role of shunt and confluence, and the L-shaped channel plays the role of distribution. The three-way O-type ball valve is equipped with double acting or single acting RC pneumatic piston actuator (Zsh horizontal piston actuator for large diameter).

Please provide the following information when ordering
1. Model; 2. Nominal diameter; 3. Nominal pressure; 4. Valve body material; 5. Flange connection type; 6. Ball core type (T-type or L-type); 7. Control mode (a, B, C, d); 8. Actuator model; 9. Accessories (solenoid valve, travel switch, handwheel);

 

1. Be careful in installation and construction, and do not hit the valve.
2. Before installation, the ball valve should be inspected to check the specification and model, and identify whether there is damage, especially for the valve stem. Also turn a few times to see if it is skewed, because during transportation, it is easy to bump the stem. Also remove the debris in the valve.
3. When lifting the ball valve, the rope should not be tied to the hand wheel or the valve stem to avoid damage to these parts, but should be tied to the valve body.
4. The pipeline connected to the ball valve must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other impurities. These debris, not only easy to scratch the sealing surface of the ball valve, in which large particles of debris (such as welding slag), but also block the small valve, so that its failure.
5. The position of valve handle rotation should be reserved during installation. 6. The ball valve cannot be used as throttling. 7. The ball valve with transmission mechanism shall be installed vertically.
