Combined DRV & 2-Way Control Valves
Supplied by
- Oventrop "Series 810" dynamic balancing valves, which hold a set flow across a differential pressure band rather than at one design point — 2–32 PSID on threaded and solder sizes DN 15–50, and 2–32 or 5–60 PSID on flanged DN 65–150. Flow cartridges run from 0.5 GPM on a ½" body up to 680 GPM on a 6" flanged body.
- Used on terminal branches in fit-outs where ceiling void depth and access panel size decide what fits, and on riser branches where the differential swings with load. Because the cartridge fixes the flow across its whole pressure band, the proportional balancing pass is removed from the commissioning programme — which is where the saving shows on repetitive floors.
