Halcyon BCD Over‑Pressure Relief Valve — Protect Your Wing from Bladder Damage

When a BCD’s bladder gets over‑inflated - from surface rises, altitude transport, or rapid inflations - the risk of bladder rupture or seam failure increases dramatically. The Halcyon BCD over‑pressure relief valve activates before that happens, automatically venting excess air to safeguard your wing. Essential for technical, travel, and rental setups, it’s a small addition that prevents significant gear damage.

Key Features & Benefits

Spring‑loaded mechanism auto‑vents excess air to prevent bladder over‑pressure
Compatible with Halcyon wings, SMBs, lift bags - supports both coarse and fine thread styles
Corrosion‑resistant design built for longevity in saltwater environments
Compact and lightweight - adds minimal bulk to your inflation system
Tool‑free installation replaces existing dump or relief valves instantly

Detailed Description
Proper control of bladder pressure is critical: over‑inflation can cause the bladder to rupture or seams to split, leading to gear failure or uncontrolled buoyancy. The Halcyon BCD over‑pressure relief valve functions as a fail‑safe - when internal pressure exceeds safe levels, its spring‑loaded valve releases air automatically, protecting the bladder from damage.

It’s designed for universal use across Halcyon wings, surface marker buoys, or lift bags, with both fine-thread (pre-2020) and coarse-thread (current) options. Installation couldn’t be simpler: unscrew the current valve or airtight cap, screw this in until snug, and you’re protected. For travel divers, tech teams, or rental gear operations, this swap boosts bladder safety without adding complexity.

The valve stays out of the way until needed - compact, lightweight, and built to resist corrosion. It adds peace of mind whether you're executing buoyancy drills, diving with altitude-adjusted inflations, or inflating lift bags. By preventing over‑pressure damage, it helps extend the life of your BCD and keeps unexpected failures off your dive plan.
