Features & Benefits
VALMATIC Segmented Ball Valve is similar to that of a conventional ball valve but with a V-notch segment ball. Coupled with the favourable characteristics of a quick action and high flow capacity of a ball valve, the V-notch segment produces equal percentage flow characteristics for precise flow control. The specially hardened and coated ball and disc design makes the valve especially suitable for media containing viscous fluids and dirty media such as sand, fibres, sludge, paper, pulp and chemicals. VALMATIC Segmented Ball Valve can be fitted with a wide variety of control options for both on-off and throttling applications.
1. ONE PIECE BODY
Rigid, one piece body design eliminates potential leakage paths caused by separate flange connections
2. V-NOTCH
V-notch design allows for precise equal percentage flow control and strong shearing ability for fibrous and dirty media
3. SPLINED STEM CONNECTION
Splined connection between the stem and ball provides additional strength under high loads, efficient torque transmission and precise control.
4. DURABLE COATINGS
As a standard, the metal seat is Stellite hard-surfaced and the disc is Hard Chrome coated for added durability and a long-lasting service life.
5. SPRING LOADED SEAT SEATING
Hexagonal springs allows for constant contact with the ball and seat, ensuring enhanced sealing performance.
6. LOW TORQUE OPERATION
With less than half surface engagement of the segment ball compared to a full bore ball valve, lower friction and lower operating torque is required. This increases the lifecycle of the valve and allows a smaller actuator to be used.
7. REPLACEABLE SEAT
The seat can be replaced without needing to disassemble the valve or actuator, making service and maintenance fast and easy.
