PRESSURE RELIEF VALVE VOYAGE MARINE Overpressure Safety Protection

The PRESSURE RELIEF VALVE VOYAGE MARINE is a high-precision safety valve designed to protect boilers, pressure vessels, marine engines, and piping systems from dangerous overpressure conditions. Designed in both Angle Type and Straight Type body configurations, this direct-acting valve automatically discharges excess fluid or gas when internal system pressure exceeds the preset setpoint, rapidly restoring safe operating limits.

Engineered in strict compliance with international safety standards—including API 520 and API 527—the PRESSURE RELIEF VALVE VOYAGE MARINE undergoes rigorous seat tightness and pop-action testing per API 527 specifications. Available in nominal sizes up to 150 mm (with larger dimensions above 150 mm custom-engineered via Voyage Marine Automation), it accommodates air, water, gas, and steam media across aggressive marine and industrial environments.

Key Features of the PRESSURE RELIEF VALVE VOYAGE MARINE

• Dual Body Configurations:

  • Angle Type: Right-angle flow pattern ideal for tight engine room manifolds, vessel deck headers, and boiler safety lines.

  • Straight Type: In-line body configuration designed for direct inline pipeline installation and space-constrained skid systems.

• API Certified Safety & Tightness: Built in accordance with API 520 sizing and set-pressure design standards and 100% seat-leakage tested under API 527.

• Multi-Media Compatibility: Fully rated for air, fresh/salt water, industrial gas, and high-temperature steam applications.

• Marine-Grade Metallurgy: Manufactured in corrosion-resistant alloys—Gunmetal (BS 1400 LG4C), Nickel Aluminium Bronze (NAB NES 747), Stainless Steel (CF8/CF8M), and Cast Steel (WCB)—for extreme pressure and temperature durability.

• Size Range Availability: Standard manufacturing up to 150 mm, with requirements exceeding 150 mm supplied directly through Voyage Marine Automation.

Primary Applications

• Shipboard Boiler & Steam Networks: Auxiliary boilers, superheaters, and steam distribution headers

• Compressed Air & Gas Utilities: Starting air receivers, control air storage tanks, and inert gas generators

• Marine Engine Room & Hydraulic Systems: Main engine cooling lines, lube oil pump discharge headers, and deck hydraulic power units

• Offshore & Industrial Processing: Seawater injection pumps, pressure storage tanks, and fuel transfer skids
