We designed our 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.
Our 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.
Our 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 vacuum fill adapter for the SDS model 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.
