Description:

【Basic Structure】: This black diving gear component is a compact BCD relief valve with a round vented housing, circular cap, and exposed side construction for a clear mechanical layout.

【Pressure Control】: As a pressure valve, it is designed to release excess air from the BCD system through a base and responsive internal components.

【Working Mechanism】: The overpressure valve includes a pull cord connected to a ribbed cone-shaped knob, giving a simple manual way to trigger venting when needed.

【Construction Feature】: This diving relief valve uses visible coil components and a sturdy compact body, combining practical function with an easy-to-recognize mechanical design.

【Use Purpose】: Built for diving gear, the valve helps support controlled pressure release during use, making it a functional part for managing buoyancy system air movement.
