Metal seat gate valve for water, sewage and neutral liquids to max. 70°C
AVK series 37 gate valves are designed with built-in safety and quality in every detail. The tough and sturdy metal seat design is well suited for use in applications where conditions are harsh with high temperature and high content of debris or other abrasives. The copper alloy metal seals are machined to a supremely fine surface finish that makes sure to close water tight under all conditions.
