Robust design, suitable for most harsh environments
The overall robust design meets and exceeds all standards for both Gas and Water applications. The design of the AVK range of PE Ball Valves ensures a long functional life cycle and is suitable for most harsh environments.

Safety connector
When over torqued no leakage to atmosphere. Replacement of connector can be done under live conditions. If the valve is over torqued during open or closing, the connector is designed to fail before the valve seals, thus preventing a leak to atmosphere. The safety connector can be replaced under live conditions.

Easy mounting of all standardised spindles
The connector is designed to adapt all extension spindles and Tee Keys according to European standards. The either blue or yellow colored bearing ring also seals off the below positioned ball spindle to avoid ingress of water and/or dirt.

Sealing assembly centred in body ensures safe float of ball between seats
The PE Ball Valves applied in water distribution systems are equipped with special designed balls ensuring a continuous flush through all hollow areas when in open position.

PE100 used for internal components
Temperature influences have equal impact on all parts Any differences in medium and/or surrounding temperatures may have an influence to the construction materials. PE100 materials are consequently used for the outer body and the internal ball and seat retainer rings. This ensures an equal expansion and/ or shrinkage throughout all components, thus maintaining their interfacing tolerances.

Low operating torque throughout the whole range
The PE Ball Valves from AVK are characterized by having a low operating torque throughout the whole range. The PE100 Ball surface interacting with high quality rubber seals give low operating torques and also avoid sticking after time. Also special designed expansion grooves in sizes as of DN65/d75mm contribute to low operating torques and avoid the necessity of gearboxes.
