Control valves can help reduce water losses and contribute to efficient water supply management by maintaining a certain pressure, flow or level, regardless of changes in the supply network.
AVK, THE SAFE CHOICE WITH 10 YEAR WARRANTY
AVK diaphragm operated control valves are designed according to EN 1074-5 and to provide network stability, accurate regulation, easy maintenance and long durability. AVK control valves are available in DN 50-600, with reduced and with full bore. Control valves with reduced bore are appropriate for most applications, as the smaller bore often offers more accurate regulation. Control valves with full bore are recommended, if high Kv values are needed, e.g. in front of hydrants.
UNIQUE DESIGN FEATURES
AVK control valves are the safe choice offering accurate regulation, easy maintenance and long durability:
•All non-coated metal parts of stainless steel AISI 316 as standard
•Fusion bonded GSK approved epoxy coating (300 micron)
•AVK’s own drinking water approved rubber compounds
•Modular pilot system enables easy fitting to other applications without replacing
the valve
•Adjustment of regulating speed for full control
•Parabolic plug design provides precise regulation and stability at low flow
•Large diaphragm secures fast reaction to minor changes in pressure
•Lifted seat prevents damage inside the valve body due to cavitation
•AVK design and manufacture with 100% pressure test and 10-year warranty
HOW CONTROL VALVES CAN BE USEFUL
Automatic control valves are used to obtain efficient pressure and flow management resulting in:
•Reduced water loss through leakages
•Reduced risk of water hammer and pipe bursts
•Less disruption to consumers
•Savings for network operators
VARIANTS AND CONFIGURATIONS
Pressure reducing, and pressure sustaining valves are part of our standard range. On request, we also offer control valve variants such as: surge anticipation valves, altitude valves, float level valves, constant flow valves, (dual) solenoid control valves, multi-function and solenoid override.
