Durapipe 2-Way VK Ball Valves

The ABS Durapipe plain end ball valve range offers a reliable, industrial-grade solution for isolating, regulating and controlling flow within ABS pipework systems. Manufactured by Durapipe from high-quality acrylonitrile butadiene styrene (ABS) and fitted with EPDM seals, these valves deliver excellent resistance to corrosion, impact and a wide range of diluted chemical media.

Available in sizes from ½" to 4", all valves in this category feature union connections, allowing the valve body to be removed for maintenance or seal replacement without cutting into the pipeline. Installation is carried out using ABS solvent cement and cleaner, creating a strong, permanent weld into the system while still offering future serviceability.

Key benefits of the Durapipe ABS ball valve range

• Durable ABS construction - lightweight, corrosion-free and impact resistant
• EPDM sealing - reliable performance with water and many diluted chemicals
• Union ends - straightforward maintenance without disturbing surrounding pipework
• Pressure rating up to 16 bar at 20°C
• Plain end connections for secure solvent-welded joints

The ABS VKD Ball Valve is a fully unionised, high-performance isolation valve designed for demanding industrial pipework systems. It combines robust ABS construction with advanced sealing and union security technologies for long-term, leak-free performance.

This valve is ideal where reliable on/off control is required across water treatment, chemical handling (diluted media) and general process systems.

What makes the VKD stand out:

• DualBlock union system prevents the union nuts from loosening under vibration or thermal expansion
• Seat Stop ball seat carrier allows micro-adjustment of the seats without draining the system
• Fully unionised body for easy removal during servicing
• Ergonomic VKD handle with built-in seat adjustment tool
• Rated to 16 bar at 20°C for industrial pressure applications

A strong all-round valve that balances durability, ease of maintenance and secure long-term operation.

The lockable VKD ball valve retains all the performance features of the standard VKD design, but adds an extra layer of operational safety through a lockable handle. This makes it ideal for systems where unauthorised operation must be prevented or where positive isolation is required for safety and maintenance procedures.

Typical applications include shared industrial systems, plant rooms, dosing installations and safety-critical pipework.

Key distinguishing features:

• Lockable handle prevents accidental or unauthorised valve operation
• DualBlock union security for vibration-resistant performance
• Seat Stop micro-adjustment for fine-tuning sealing pressure
• Union-end construction allows valve removal without pipework alteration
• EPDM seals + ABS body provide corrosion resistance and long service life
• 16 bar pressure rating at 20°C

This version is the go-to option when controlled access and safety compliance are just as important as performance.

The ABS VKR Metering Ball Valve is designed for applications that require accurate and repeatable flow regulation, not just simple on/off isolation. Built on the VKD platform, the VKR introduces an advanced patented fin-shaped metering ball that delivers smooth, linear flow control across the entire operating range.

This makes it ideal for dosing systems, recirculation circuits, balancing applications and industrial water management where precision matters.

What sets the VKR apart:

• Patented metering ball geometry provides linear, accurate flow regulation
• Graduated 5° position indicator for precise and repeatable flow settings
• DualBlock system prevents union nut loosening
• Seat Stop micro-adjustment allows seat tuning without depressurising the line
• Fully unionised body for easy maintenance and inspection
• EPDM sealing and ABS construction for chemical resistance and durability
• 16 bar pressure rating at 20°C

The VKR is the preferred choice when fine flow control, repeatability and long-term stability are essential.

All Durapipe ABS ball valves in this category are supplied with plain solvent-weld ends and must be installed using:

• ABS cleaner for proper surface preparation
• ABS solvent cement for permanent, pressure-rated bonding

These valves are designed specifically for ABS pipe systems and should not be used with PVC or other plastic materials using incompatible solvent cements.
