PREVCO SUBSEA LLC launched the new Dual Poppet Pressure Relief Valve. The latest evolution of their pressure relief valves features a modified ‘High-Reliability’ valve with redundant seals and a copper debris cap. The standard valve has been successfully in operation for many years and the latest innovation is to streamline the dual poppet valve and add the debris cap. Some deployments call for long-term subsea applications and often in deep and turbid water. The copper debris cap, will help to prevent the build-up of marine growth which could otherwise cause the valve to malfunction.

They also highlighted stock off-the-shelf pressure vessels in Aluminium and PVC hybrid.

They explained: “As far as we know, we’re the only company offering a stock option for subsea housings and these are becoming more and more popular as the cost, lead-times and quality are excellent compared to the other option of designing in-house.”

Their featured exhibit was of use to any subsea application where there is a need to enclose electronic equipment and take it subsea.

Other exhibits on their stand will include stock and custom housings in Aluminium, Stainless and Super Duplex stainless steel, Titanium, Ceramic and plastic plus a range of pressure relief valves, vent plugs and a portable vacuum leak test kit. These are of use to enclose electronic equipment subsea.

Their exhibits were of interest to those attending the Hydrography, Geophysics and Geotechnics; Marine Renewables; Ocean Observing Systems: Marine Technology and Services Sector Role in the Blue Economy; Oil & Gas: What’s next for Ageing Offshore Assets?; Positioning & Metrology; and Unmanned Vehicles and Vessels Showcase conference streams.

The company has expanded over the last year, moving to a larger facility and taking on more staff. They increased their pressure testing capability with a new 15,000 psi test tank and are testing both in-house and outside pressure vessels. They’ll have a selection of their housings on display at the show, together with other accessories including, pressure relief valves, dual seal vent plugs, Zinc anodes and a portable vacuum leak test kit.
