Product Introduction:

Explosion proof electric three-way L-shaped ball valve Q944FIt is composed of an electric actuator and a three-way ball valve. It is a rotary cut-off and regulating valve with the advantages of tight closure, compact structure, light weight, and easy maintenance. The electric three-way ball valve is powered by 220V single-phase AC power and receives switch signals from the control system. It drives a reversible single-phase gear reducer through single-phase power switching, allowing the ball valve to plan the pipeline according to the specified requirements. The two seat sealed electric three-way ball valve has a compact structure, beautiful appearance, and good sealing performance. It can switch the flow direction of the medium in the pipeline and also connect or close two perpendicular channels. The four seat sealed electric three-way ball valve has a beautiful appearance, compact and reasonable structure. It can not only switch the flow direction of the medium, but also connect the three channels to each other. Currently, any channel can be closed to connect the other two channels, flexibly controlling the merging or splitting of the medium in the pipeline. Electric three-way ball valves are suitable for switching the flow direction of media and diverting or mixing fluids in pipeline systems such as water supply, petrochemical, metallurgical, mining, textile, energy, papermaking, food, steel, etc.

Main Features

Compact structure, quick opening and closing, smooth flow channel, and low fluid resistance.
Good sealing performance: Utilizing the four-way valve seat material of polytetrafluoroethylene elastic deformation to achieve leak free sealing.
One valve for multiple purposes: Any port can be used as an inlet without leakage, while a three-way valve can be made into either an L-shaped or T-shaped port.
Easy maintenance: After the system is depressurized, it can be inspected and repaired without removing the entire valve body.

Valve control mode

Electric three-way ball valves are divided into L-shaped and T-shaped, and the direction of medium flow is shown in the following figure. The L-type electric three-way ball valve is suitable for switching the flow direction of the medium, which can connect two perpendicular channels. The T-shaped electric three-way ball valve is suitable for dividing, merging, or switching the flow direction of the medium. The T-shaped hole can allow three channels to communicate with each other or connect two of them. The electric three-way ball valve generally adopts a two seat structure, and can also adopt a four seat structure according to customer requirements.
