Cargo Tank Pressure Relief Valves are safety devices designed to prevent overpressure in tank systems by releasing excess pressure. They ensure the structural integrity of tanks during transportation or storage of liquids and gases. These valves are critical for maintaining safe operating conditions and preventing potential hazards.

Size: Typically ranges from 1" to 4" nominal diameter.

Grade: Complies with ASME, API, or ISO standards, often rated for high-pressure applications.

Viscosity: Suitable for low to high-viscosity fluids, depending on valve design.

Buoyancy: Designed to prevent floatation issues, with weight-adjusted models for submerged applications.

Material: Constructed from stainless steel (SS316, SS304), carbon steel, or specialty alloys for corrosive environments.

Pressure Rating: Commonly 150 PSI to 600 PSI, with higher ratings available.

Temperature Range: -40°F to 400°F (-40°C to 204°C), varies by material.

Relief Mechanism: Spring-loaded, pilot-operated, or rupture disc types.

Certifications: API 2000, ASME Section VIII, or EN 14595 compliance.

Connection Type: Flanged, threaded, or welded ends.

Seal Material: Viton, PTFE, or Buna-N for chemical resistance.
