Rp123000.00
Product Description
The Crosby™ 2” x 3” Pressure Relief Valve is a high-performance spring-loaded safety relief valve engineered to provide automatic overpressure protection for pressure vessels, piping systems, boilers, steam lines, and industrial process equipment.
Designed and manufactured in accordance with ASME standards, the valve delivers reliable relieving performance, excellent seat tightness, and stable reseating characteristics under demanding operating conditions. The valve automatically opens when system pressure exceeds the preset set pressure and closes tightly once normal operating pressure is restored.
The 2” ANSI Class 300 inlet and 3” ANSI Class 150 outlet configuration provides efficient relieving capacity for steam, gas, vapor, and liquid applications commonly found in oil & gas, petrochemical, refinery, chemical processing, and power generation industries.
