"What a difference a valve makes!"

NAUTEC Valve Manufacturer:

High quality German engineering for the toughest of dives

NAUTEC valves product lines: SportLine | ProLine | DarkLine

We use the same high-quality components for all our valves, regardless of which product line. High pressure seat and spindle, as well as all O-rings are suitable for air (Air), oxygen enriched air (Nitrox) and pure oxygen (Oxy). Externally, the three series differ only in the type of coating (standard chrome or black chrome) and the handwheels (ABS plastic or rubber knobs).

The values of our valves and it’s mechanics:

Nautec valve bodies and spindles are machined from a special brass-alloy. The properties of our special brass are high strength, excellent machinability, exceptional wear resistance, and superior corrosion resistance. Also can our lead-free material, reduce the environmental burden on society.

Our key of making a long-lasting valve is the spindle, which is precisely guided by the top screw, and the engagement of it in the seat by means of an allen key instead of a spade.

Tests have proven that this design is far advanced to conventional valves. It can easily stand up to a 80% higher torque. NAUTEC-Valves are simply designed for long-term usage.

All NAUTEC valves are: LEAD-FREE.

All NAUTEC valves are: 100 % oxygen-compatible.

(in unused conditions)

All NAUTEC valves are: produced with gleitmo 599.

Our valves were presented to BAM* for testing. They have passed all the tests listed here.

BAM-Hydraulic pressure test 675 bar
BAM-Material test
