  • products details

YFL four way ball valve has four valve seats and four flow passages, it can change the flow directions of two kinds of mediums simultaneously by 90 degree rotation of ball.

The four way ball valves are used to replace complicated piping system with four valves for clockwise and anticlockwise water supply for condensers  in hydro power plants, coal-fired power station and nuclear power plants. They are also applicable for distributing heat and city gas; exploiting, extracting and transporting of coal and mineral; Metallurgy, Oil & Gas, Chemical, food & pharmaceutical, municipal water supply and drainage etc.

With one four way ball valve, the procedure is simplified, the cost is saved; the operation is more easier, the control is more convenient and it is good for synchronization. The operation of four way ball valves can be manual, pneumatic or electric.

There are L type four way ball valves and T type four way ball valves for different working conditions. The working principle for L type four way ball valves is as follow:
