Anthony Whittam
Head of Smart Water and Pressure Management
Resilient seated gate valve to BS EN 1074-2 / BS 5163-1 for water and waste water. Temperature range: -10° C to +70° C. 10% solid matter. Insulation essential for temperatures of 0° C and below. Maximum Working pressure: 16 Bar.
The 21/50-009 Smart Water resilient seat, wedge gate valve for isolation purposes. These valves are equipped with a VIDI Positioner, a smart device for indicating the position of gate valves and whether it is open, close, or any percentage in between and transmits the data wirelessly. Based on the data provided, water utilities can optimise the operation of the water distribution network, asset auditing, efficiently lower water loss.

- Safety Note:
- The valves now accomodate lifting bars for the safe handling of valves. These lifting bars are rated to the weight of the bare valve and stem cap (where fitted) only and should not be utilised if the valve is fitted with pipe, mechanical pipe joints, gearboxes, actuators or any other external fitment. AVK will not accept any responsibility for loss or damage if the lifting bars are not used in strict accordance with this guidance.
