Valterra check valve
Valve specially designed to limit load losses.
This valve does not have a spring-loaded ball but a flexible valve which causes much less load losses.
This accessory can be installed vertically or horizontally (in the latter case, pay attention to the position indicated on the body of the valve).
Available in 32 (*), 50 and 63 mm.
Available in 90 mm in another range that we also present in this section.
Max. Recommended flow:
- Valve of 32 mm (*): 4 m3 / hour
- 50 mm flap: 8 m3 / hour
- 63 mm flap: 14 m3 / hour
(*) Valve with a diameter of exactly 33 mm
It is possible to glue them with Griffon WDF-05 glue, but it is preferable to assemble them with flexible sleeves 40 mm.
The valves 50 and 63 mm can be glued without any difficulty with the same adhesive.
