We recently completed the manufacture of a DN700 Uniwat^® butterfly valve for a drinking water treatment plant in Madrid.

Comeval’s own brands not only operate beyond our borders but also bring all their advantages to installations here in Spain.

In this case the valve operation is worth highlighting: it is driven by a double acting pneumatic actuator with a smart positioner to control the flow, with limit switches built into it, as well as a declutchable handwheel for manual operation in an emergency.
