ECCENTRIC SEGMENTAL BALL VALVE

ECCENTRIC TYPE SEGMENTAL BALL VALVES

The PROVAL segmental ball is an eccentric plug, high performance rotary control valve. Designed for use in a wide variety of applications ranging from low pressure, high “Cv” to slurry and pulp services, to oil and gas services. The PROVAL segmental ball can handle shut-off pressure drop up to 50bar. Operating temperatures can from -50°C to 450 °C.

The PROVAL segmental ball control valves consist of a straight valve body with less flow resistance and separable plug with flow guide that rotates eccentric.

BALL VALVE

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.

CHARACTERIZED SEGMENTED BALL

CHARACTERIZED SEGMENTED BALL

segmented ball valve which features a patented contoured segmented V-notch ball. The V-notch ball produces an equal-percentage flow characteristic allowing for wide rangeability and a broad control range. The segmented ball also provides a non-restrictive flow path through the valve allowing for high capacity flows. The Vee-Ball valve features a variety of seals to allow for excellent shutoff and shearing between the ball and seal upon closure.

The splined drive shaft of the Vee-Ball combines with a variety of power and manual actuators to provide reliable, high-performance throttling or on-off operation for many different applications.
