Wafer Type Segment Ball Valves: Compact, Precision Flow Control for Slurry & Viscous Media
Overview of Vcore Wafer Type Segment Ball Valves
Key Features & Benefits
Ultra-Compact Wafer Design:
Thin body profile installs directly between two pipe flanges using long stud bolts, eliminating the need for separate flanged connections. Saves up to 70% installation space compared to flanged ball valves, making it perfect for skid-mounted equipment, compact process lines, and retrofitting projects.
Lightweight construction reduces structural load and simplifies handling during installation or maintenance.
V-Notch Segment Ball for Precision Control:
The V-shaped cut on the segment ball creates a variable flow path, delivering a near-linear flow characteristic (equal percentage or linear). This enables precise flow regulation from 0-100%, with a control rangeability of up to 300:1—far superior to standard ball valves.
The sharp-edged V-notch provides powerful shearing action during rotation, cutting through fibrous materials, particles, and sludge to prevent clogging. The wiping effect between the ball and seat keeps sealing surfaces clean, reducing downtime for maintenance.
Robust Sealing & Corrosion Resistance:
PTFE/RTFE or metal-to-metal seat options ensure bubble-tight shut-off (ANSI Class VI) even for high-pressure or corrosive media.
Stainless steel body and ball resist corrosion from chemicals, wastewater, and pulp & paper processing fluids, extending service life in harsh environments.
Low Torque Operation & Actuator Compatibility:
Low-friction stem design minimizes operating torque, allowing easy manual operation via the blue lever handle or seamless integration with pneumatic, electric, or hydraulic actuators for automated control systems.
ISO 5211 top mounting pad ensures quick and standardized actuator installation, supporting modular upgrades for smart plant operations.
Cost-Effective & Low Maintenance:
No external flange connections reduce material costs and potential leak points.
Simple structure with fewer moving parts means minimal maintenance requirements—just periodic seat inspections and stem lubrication to keep the valve performing reliably for years.
