Nuova Simonelli Neplax Expansion Valve – 16.5 Bar
Neplax-body expansion valve with a Viton seat, factory-calibrated to release at 16.5 bar.
SPECIFICATIONS
- 16.5 bar calibration
- Viton seat
- 1/8" M thread to 8 mm barb outlet
COMPATIBILITY
- Fits: Nuova Simonelli boiler expansion circuits
- Works with: CP_1 tubing (5 x 8mm)
INSTALLATION
DIY-friendly for anyone comfortable working on boiler plumbing.
PRO TIPS
- The Viton seat holds calibration better under sustained heat than EPDM alternatives, if you're replacing a valve that's drifted from spec or won't hold pressure, this is a durability upgrade, not just a like-for-like swap.
