DeepGuard 6000M Pressure Relief Valve – 316 Stainless Steel | 7/16" Port | Cracking Pressure 5–6 PSI | Rated to 6,000m Depth
Engineered for protection in extreme subsea environments, the DeepGuard 6000M Pressure Relief Valve is specifically designed to safeguard critical underwater systems against overpressure scenarios during deep-sea deployments. Designed with marine research institutes, commercial ROV operators, subsea oil and gas installations, and university oceanography programs in mind, this relief valve provides precise pressure tolerance to deliver consistent performance—even at depths of 19,685 feet (6,000 meters) below sea level.
Crafted from marine-grade 316 stainless steel, this valve provides corrosion resistance in high-salinity environments. With a cracking pressure of 5–6 PSI, it activates precisely when needed to release excess pressure and prevent system damage. Its 7/16" straight-thread port design eliminates the need for an SAE adapter, streamlining integration into tight or modular subsea assemblies.
For added functionality and pre-deployment testing, the DeepGuard 6000M is compatible with an optional Vacuum Attachment, enabling you to easily pull a vacuum on your pressure housing or instrument enclosure through the same 7/16" port. This feature is ideal for verifying the integrity of seals, monitoring internal pressure drops, and ensuring security prior to launch. The attachment installs in seconds and provides a reliable method for field verification, eliminating the need for additional ports or dedicated hardware.
Key Benefits & Technical Features
- High-pressure depth rating: Tested and rated for operation up to 6,000 meters (19,685.04 feet), ideal for abyssal and hadal zone missions
- Corrosion-resistant construction: Built from 316 stainless steel, offering reliable endurance in saltwater and chemically aggressive subsea environments
- Precision cracking pressure: Set to relieve at 5–6 PSI, safeguarding delicate housings and enclosures from overpressure
- Compact port compatibility: 7/16" thread eliminates SAE port requirements, allowing for universal fit in deep-sea housings and instrument panels
- Field-tested durability: Proven performance across ROVs, AUVs, pressure housings, and underwater junction boxes in continuous deployment scenarios
Intended Use and Application
The DeepGuard 6000M is specifically engineered for marine research labs, offshore energy companies, ROV/AUV design teams, and university-based oceanographic expeditions operating at full ocean depth. It is ideal for safeguarding electronic housings, pressure vessels, or mechanical enclosures from pressure spikes caused by thermal expansion or fluid ingress during descent or ascent.
Installation is straightforward via the 7/16" threaded port, allowing it to be mounted directly to enclosures, T-fittings, or junction hubs without the need for additional adapters or conversion kits. When paired with the Vacuum Attachment, users gain a fast, effective method to validate seal integrity and pressure security before deployment. Whether protecting a mission-critical sonar system or an experimental sensor array, this valve delivers reliable performance throughout the entire underwater mission.
