Compact monobloc valve in heavy marine brass with Viton O-rings, specifically designed for decompression and stage cylinders.
The Scubatec Single Stage Valve, available at DIR-STORE, is the reference component for setting up decompression and stage cylinders in technical and exploration diving. Entirely machined from a single block of high-strength drawn marine brass and finished with heavy anti-corrosion chrome plating, this valve boasts a clean and compact design (without pre-fittings or plugged secondary outlets). This linearity eliminates snag points, facilitating hose movement and preventing tangles during delicate gas-switching maneuvers or cylinder removal on a wall.
Available Configurations and Thread Pitches:
-
Standard M25x2 Thread (Right or Left): The universal pitch for almost all aluminum (e.g., S40, S80) or steel cylinders. It can be ordered in both Right (DX) and Left (SX) versions to allow for mirrored and symmetrical positioning of the handwheels and first stages on the diver's sides.
Key Features and Benefits:
-
Natively Oxygen Clean: Assembled directly in the factory with Viton O-rings for high chemical-thermal stability and special oxygen-compatible lubricants.
-
DIN 232 Bar Safety Connection: Standard DIN (G 5/8) screw connection that offers exceptional mechanical sealing of intermediate pressure and prevents accidental extrusion of the first stage gasket.
-
Soft-Grip Rubber Handwheel: Supplied as standard with a soft rubber knob resistant to violent impacts. The deep geometric sculpting ensures a firm grip and immediate fluid maneuverability even when wearing dry gloves or with cold hands in deep water.
