Description
The PVC flanged butterfly valve (Atlas Pool, code UHPVC21) is a thick-walled U-PVC model with a blue handle and a nominal pressure of PN10. It is connected with flanges to the pipes of the pool filtration system or the water supply line.
In brief
- 12 diameters from 63 to 315 mm
- Nominal pressure PN10
- U-PVC flanged valve with handle
- EPDM seal for water
Scope of delivery
The set contains two flanges, two adapters for them, and brass-coated bolts and washers. The connection is bolted – it is not glued and has no thread – so the valve is easy to remove for repairs.
Application
It is suitable for the thinner branches to the filter, but also for the main lines of larger systems. The handle turns the disc and closes or opens the water.
