Specifications

Medium-profile. Stable by design

The T02 Series defines a medium-profile relief platform for buoyancy and inflatable systems built around the T02 interface. It supports stable integration and dependable relief function within interface-specific system layouts. A medium-profile platform built for reliable relief integration.

Interface architecture. Defined by Series.

Each OPV Series is engineered around a dedicated flange geometry, defining fit, sealing and retention at the buoyancy-device boundary. Lid design and valve configuration vary within the Series; compatibility follows the interface geometry.

Built to integrate. True to your setup.

Whatever the field runs, HYDPRO builds to it natively: every established mount standard, thread, and host geometry, covered from the factory. Your setup stays as it is, integration stays clean, and the response repeats: the same command, the same result, on every dive.

Italian engineering. Predictable control

Each HYDPRO device is engineered and manufactured in Italy: one chain from raw material to release. Polymer families are selected for constant immersion, precision-drawn brass runs on in-house CNC lines, and every device leaves built, tested, and signed off under one roof.
HYDPRO power unit manufacturing: CNC machining, hand assembly, and the finished valve underwater

Proven by divers.
Refined by decades.

Four decades in the water stand behind the current generation. What wears, what binds, what drifts out of tune comes back from real dives to the bench, and the next revision answers it. Control you can feel, refined one generation at a time.
