Three-Way Ball Valves

3wbv_500_1

3wbv_200_2Three-way ball valves are a very versatile valve design which can be used for many different popular applications by combining the T or L port with dedicated actuation. They are used for switching, converging and diverging pipeline medium flow direction.

It is widely applied in metallurgy, mine, petroleum, chemical industry, electric power, light industry, shipping industry and automation control systems, suitable for service conditions such as switching, mixing and diverging of fluid, gas and power.

The three-way / four-way ball valve is provided with reliable sealing and smooth flow channel so as to ensure accuracy of opening and closing through small fluid pressure loss and stable flow channel.

According to the forms of flow channel, the valve can be classified into Y” pattern three-way ball valve, “L” pattern three-way ball valve, “T” pattern three-way ball valve and “LL” pattern four-way ball valve. The forged 3 way ball valve design is based on a solid forged block with three closures and a trunnion mounted ball.
