The ABS VKR Metering Ball Valve is engineered for applications where precise and repeatable flow control is essential. Building on the durability and reliability of the VKD platform, the VKR introduces a unique metering capability through its patented fin-shaped ball design. This innovation provides exceptionally linear flow characteristics across the entire operating range, enabling fine adjustments that are difficult to achieve with standard ball or diaphragm valves.

A graduated Metering Control Indicator on the handle allows users to set and read flow positions at 5° increments, delivering accurate, predictable regulation for dosing and balancing duties. The valve also retains Durapipe’s proven DualBlock system, preventing the union nuts from loosening due to vibration or thermal cycling, and the Seat Stop system, which allows micro-adjustment of the ball seats without draining the pipeline.

Like all VKD/VKR valves, the VKR model is fully unionised, allowing the valve body to be removed for maintenance or seal replacement without altering the surrounding pipework. With EPDM seals supplied as standard and compatibility with electric positioning actuators, this valve is ideal for systems requiring high-resolution flow control and long-term dependability.

• Precision metering performance: Patented fin-shaped ball design delivers smooth, linear flow regulation with minimal pressure loss
• Graduated indicator: 5° handle increments enable repeatable and accurate flow setting
• DualBlock union security: Prevents loosening of union nuts under system vibration or thermal expansion
• Seat Stop micro-adjustment: Allows seat tuning and load compensation without depressurising the system
• Service-friendly construction: Union ends allow fast removal of the valve body for cleaning or seal changes
• Reliable EPDM seals: Suitable for water and a wide range of diluted chemical media
• Durable ABS body: Lightweight, corrosion free and ideal for industrial ABS pipeline installations
