CONCENTRIC 2-WAY, 3-WAY BALL VALVES
The PROVAL provides 2-Way ball valves with a special inner valve which can be fully opened or closed by simply causing the stem to make a 90° turn. The off take from a ball valve, when totally opened, has same bore as the pipeline and its fluid resistant is negligible. For this reason, this automatic valve is best suited to on-off service, controlling various types of liquid, gas and slurry.
The PROVAL 3-Way ball valves are available in two types. The diverting type (L) splits flow by switching between two directions of inlets while the converging type (T) mixes two fluids by switching between two outlets. Both of those moves are made with a mere quarter turn of the stem.
