ASTM A182 F304 Safety Valve, DN8, PN350, Card Sleeve Joint

Key Specifications / Features

The ASTM A182 F304 Safety Valve is a high-pressure safety valve designed for critical applications. Manufactured from forged stainless steel, it offers superior durability and corrosion resistance. With a DN8 (1/4 inch) size and rated for PN350 (Class 2500 LB) pressure, this valve ensures reliable performance under high-pressure conditions. It features card sleeve jointed ends for secure and efficient installation.

The high-pressure card sleeve joint safety valve is primarily designed for use in steam boilers, dyeing machinery, garment steaming and ironing machines, leather machinery, chemical corrosion-resistant machinery, water treatment equipment, and food machinery. Constructed from bronze material, it is compatible with air, steam, water, and similar media. The main function of the micro-opening imported high-pressure stainless steel pressure relief valve is to maintain system pressure below the set threshold. When the system pressure exceeds the set pressure of the relief valve, it automatically opens to release excess pressure, thereby protecting the system.
