Double Regulating Valves (DRV)

Our range of double regulating valves is designed for manual flow balancing and isolation in hydronic heating and cooling systems, with memory stops that allow preset valve positions to be restored after isolation. FloControl offers the most comprehensive range of double regulating valves (DRVs), also known as variable orifice double regulating valves or DRV valves, to introduce a preset system resistance whilst offering the opportunity to isolate and return to the preset position. Traditional globe-style double regulating valves are threaded from ½” – 2” and flanged 50 mm – 600mm. Butterfly Valve style 65 mm, 600 mm double regulating valve for applications with space limitations and cost-effectiveness.
