SeaVent® Relief Valves
DeepSea Power & Light designed their SeaVent pressure relief valves (PRVs) to meet critical subsea specifications for a variety of applications. Models are available with adjustable cracking pressure, a selection of materials, and an 11,000 m depth rating. A 6,000 m depth rating is standard.
The SeaVent Double Dual Seal (DDS) uses dual O-rings for redundant protection against leaks. Hexagonal sides at the base of the DDS allow for easy installation with a standard wrench. The DDS is offered in either PEEK or titanium with a cracking pressure of 10 psi. A vacuum and fill attachment is available.
The Single Dual Seal (SDS) can be specified with a cracking pressure range of either 5-15 or15-25 psi. Materials include aluminum, stainless steel, or titanium. A vacuum attachment is available.
The Single Seal SAE (SSS) is available in 316 stainless steel with a cracking pressure range set from 5-15 or 15-25 psi. There is no vacuum fill option for this configuration.
The Single Seal Face (SSF) is our original PRV model still used in the field for its economical and efficient design. The cracking pressure range is 5-15 psi. *This model is not recommended for new designs*
The vacuum fill adapter for the SDS and SSF models is supplied in aluminum and includes a 2-209 o-ring to seal to the SeaVent outer body. A standard 1/4 inch NPT Male Threaded pipe adapter with appropriate hose size fitting (not supplied) is required to attach to the vacuum fitting.
