PN40 Semi-Lugged High Performance Double Regulating Butterfly Valve

Semi lugged carbon steel high performance butterfly valve, fitted with gear operator for infinitely variable settings and stainless steel memory stop feature (DRV) to precisely set and retain the desired maximum opening position differential pressure. Once set, the valve can be closed and re-opened accurately to the pre-set differential pressure.

The product is a commercially attractive option compared to traditional Globe-style double regulating valves. The butterfly valve concept is space saving and easier to support when weight is a concern. The valve is also available in large sizes up-to and including 800 mm diameter.
