SeaVent Relief Valves
-
- Multiple material options
- Adjustable cracking pressure
- 6,000 m or 11,000 m depth rated
- Vacuum and fill attachments available
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 5 psi. A vacuum and fill attachment is available.
The Single Dual Seal (SDS) has an adjustable cracking pressure range of 5-15 and 15-25 psi. Materials include aluminum, stainless steel, or titanium. A vacuum attachment is available.
Our Single Seal SAE (SSS) is available in 316 stainless steel. The SSS has an adjustable cracking pressure range of 5-15 and 15-25 psi.
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.
Depending on your connection, some of the design files are larger and will take time to download.
