Key Specifications / Features
The Steam Jacketed Safety Valve, designed with balanced bellows and built to API 526 standards, features a stainless steel ASTM A351 CF8 body for strength and corrosion resistance. With a 2-inch (DN50) size, it supports PN16 and Class 150 LB pressure ratings, and comes with RF flanged ends for easy installation. Ideal for steam applications, this safety valve ensures reliable pressure relief, maintaining system integrity and safety under high-pressure conditions.
The Safety Valve is specifically designed for use in polyester, ethylene, urea, and other industrial processes. This safety valve is equipped with an Insulation Jacket and a steam purge joint to ensure safe and reliable operation of the system.
The discharge area of the safety valve is calculated based on the cylindrical or conical surface formed between the valve disc and the valve seat. This design makes it particularly suitable for applications with small discharge capacities, large back pressures, and stable system pressures. The Safety Valve provides a reliable solution for maintaining system safety and efficiency in demanding industrial environments.
