Halcyon Streamline P-Valve

Overview

Halcyon's Streamline P-Valve is a balanced P-valve system for drysuits, with a body machined from one solid piece of Delrin. Its low-profile cap keeps drag and snag hazards down, and a dual check-valve system adds redundancy to help prevent water ingress. Halcyon designed it for long-duration diving, including cold water and extended technical dives.

Key Features

• Balanced, low-pressure design: Reduces resistance during use.
• Dual check-valve system: The dual check valves provide redundancy and help prevent water ingress.
• Secondary check valve: A second check valve equalizes suit gas with the catheter assembly, so there is less pressure resistance.
• Single-piece Delrin body: The body is machined from one solid piece of Delrin, a durable material.
• Low-profile threaded cap: The external cap protrudes approx. 15 mm (5/8 in) from the suit surface, which limits drag and snag hazards.
• Sealable venting: Venting runs through the catheter and tubing, and the valve can be closed fully to keep external water out.
• Aquaseal-bonded assembly: Internal and external components are bonded with Aquaseal for a watertight join.
