Standard-profile with Shield Technology for debris protection.

OPV P01 Shield: 400 l/m exhaust, Shield tech debris protection, conic coil spring, 53mm 8-ridge interface

Specifications

Standard-profile. Shielded against debris exposure

The P01 Series in Shield configuration extends the standard-profile relief platform for buoyancy and inflatable systems built around the P01 interface. Shield Technology adds passive debris protection where external contamination exposure is more demanding. A protected evolution of the established P01 relief layout for standard-profile system 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.
