APEX Tec-Valve Trim ProLine / M25 / Air 300 bar (without case)

The NAUTEC APEX Tec-Valve Trim ProLine is designed for compressed air double cylinders with flange diameters of 140 or 171 mm and an operating pressure of 300 bar. Built for advanced technical diving, this professional valve trim delivers maximum safety, redundancy, and precise gas control.

The ProLine valve trim consists of:

• 2 × Nautec SL-90° extendable valves (left and right)

• 1 × radially sealing TEC manifold

• Full-Metal-Core Rubber Knobs

• 2 × Nautec micro filters

• 2 × blind stops for G 5/8” regulator connections

All valve outlets can be shut off independently. Gas flow between both cylinders can be safely isolated using the Nautec TEC manifold positioned between the two flanges. Opposite the handwheel is a 7/16″ connection port, suitable for a stub pressure gauge or dive computer transmitter.

For other cylinder diameters, please contact us and provide the exact required length (see PDF for reference).

The valve trim is 100% oxygen-compatible (in unused condition) and lead-free, making it suitable for demanding technical and expedition-level diving.

⚠️ Important notice:
Do not attempt to repair NAUTEC valves yourself.
