Pneumatic 3 way ball valve L port or T port introduction
Pneumatic 3 way ball valve L port or T port composed of flange or threaded 3 way ball valve and double acting or single acting pneumatic actuator, Pneumatic 3 way ball valve L port or T port is used for medium diversion, confluent and flow direction switching, any pipe can be used as an inlet or outlet.Pneumatic 3 way ball valve L port or T port divided into pneumatic  3 way L port ball valve and pneumatic 3 way T port  ball valve, 3 way ball valve with pneumatic actuator can meet different production process requirements.Pneumatic three way L type ball valve is to cut off two of the three pipelines, and pneumatic three way T type ball valve realizes the confluent and diverging of the three connected pipelines.Pneumatic three way regulating ball valve is matched with electric valve positioner, and the operation can be controlled by inputting 4 ~ 20mADC signal and 0.4 ~ 0.7mpa air source, so as to realize the adjustment of pressure, flow, temperature, liquid level and other parameters.TPneumatic 3 way ball valve L port or T port stroke limit switch, solenoid valve, pressure reducing valve and air source of 0.4-0.7mpa can realize switch operation, and send two pairs of passive contact signals indicating the valve switch.Thread 3 way ball valve with pneumatic actuator is widely used in chemical industry, petroleum, light textile, electric power, food pharmaceutical, refrigeration, aviation, aerospace, papermaking and other industrial fields.
