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.
FEATURES
- · Both directions
- The valve is tight in both directions owing to its Symmetrical construction, which often, means double life time.
- · High capacity
- When the valve is fully open, its flow resistance is at the minimum possible, it is equivalent to straight pipe.
- · Dynamic self-adjusting center-line
- Tolerance between body and seat allows the ball to maintain its position.
- · No leakage
- The Teflon seat valves, no visible leakage is allowed.
- · Low torque for Easier operation
- Easy to manually operated and cost-saving for actuation.
