Single Tap LONG M25x2 - Polaris

Single modular valve with extended manifold and side plug, available in both 230 bar (DIN/INT convertible) and 300 bar high-pressure versions.

The Polaris LONG series single valve, available on DIR-STORE, is a high-performance modular valve developed to offer maximum versatility, ergonomics, and safety in diving. Thanks to its extended profile (LONG), the knob is slightly more distant than traditional valve bodies, facilitating grip and accessibility behind the diver's neck even in conditions of reduced mobility. Equipped with a secondary outlet sealed by a reinforced side plug, it allows the system to be converted or expanded according to the diver's technical evolution.

Selectable Fill and Pressure Options:

When purchasing, the valve can be configured according to the operating specifications of your cylinders:

• 230 bar Version (DIN/INT Convertible): Maximum flexibility. Features a DIN screw connection and includes a removable insert (plug) to make it compatible with international clamp (INT) first stages when needed.
• 300 bar Version (Native DIN): Designed with reinforced structural thicknesses to handle very high pressures with complete peace of mind. Features a deep 7-turn DIN thread (ISO 12209) and, for safety reasons, does not accept INT inserts.

Symmetric Configuration and Modularity:

The valves can be purchased individually for a custom setup of single cylinders, Sidemount systems, or stage cylinders:

• Right Version (DX): Standard configuration with the handwheel positioned on the diver's right side.
• Left Version (SX): Mirror configuration with the handwheel on the left side, ideal for a symmetrical flow arrangement (e.g., stage or side-mounted cylinders).
• Upgrade Readiness: By removing the blank side plug, a central isolator can be inserted to couple cylinders in an isolatable twinset, or a second fixed turret can be added to transform the valve into a dual-outlet valve.

Key Features and Benefits:

• NBR Seal Reliability: Assembled as standard with high-quality NBR compound O-rings and friction-resistant lubricants, ensuring perfect air tightness, stability, and a long operating life before overhaul.
• Heavy-Duty Chromed Marine Brass: The valve body is made of high-strength stamped marine brass, protected by a thick polished chrome plating that shields the metal from salt corrosion and preserves its structural integrity against accidental impacts.
• Ergonomic Soft-Grip Handwheel: Equipped with a shock-resistant black rubber knob featuring wide geometric grooves. The design ensures exceptional grip and smooth opening or closing maneuvers, even with cold hands or wearing dry gloves.
