Mamoun Humayra
Water Product Manager
Resilient seated, wedge gate valve for isolation purposes suitable for use with water to a maximum temperature of up to +70°C. 10% solid matter. Insulation essential for temperatures of 0° C and below. Maximum working pressure: 16 bar.
The AVK Series 21/87-001 resilient seated, wedge gate valve for isolation purposes, prepared for installation of AVK Smart Water surveillance and measurement equipment. 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.
