Description
Microdos injection check valve 1/2” 4×6 mm with gasket – 11.100.450
Ensure safe, precise chemical dosing with this original Microdos injection check valve. It connects a 4×6 mm dosing line to a 1/2” injection point and uses a built-in non-return mechanism to prevent backflow, pipe drain-down and unwanted mixing in the return line.
- 1/2” male injection valve with integrated non-return
- 4×6 mm hose connection for standard dosing lines
- Includes flat sealing gasket for leak-tight installation
Compatibility
Designed for Microdos dosing systems and many pH/ORP (redox) or chlorine controllers that use 4×6 mm tubing. Commonly paired with Micro pH, Micro Rx, Micro UP and ME/MP series units. Also suitable as a universal replacement on installations with a 1/2” female injection port.
What’s included
- Injection check valve 1/2” × 4×6 mm (ref. 11.100.450)

Installation tips
- Fit into a 1/2” female boss (e.g., on a saddle clamp or tee) at the designated injection point on the return line.
- Tighten by hand, then a quarter-turn with a suitable wrench; do not overtighten.
- Prime the dosing line and check for leaks; rinse the valve with fresh water after seasonal shutdowns.
