Product Overview
The Swagelok RL3 is a precision-engineered proportional relief valve designed for accurate pressure control in demanding industrial fluid and gas handling systems. As a direct-acting, spring-loaded proportional relief valve, the RL3 provides smooth, infinitely adjustable cracking pressure regulation proportional to the applied setpoint, making it ideal for applications requiring fine pressure modulation rather than simple on/off overpressure protection. Manufactured by Swagelok, a globally recognized leader in high-integrity fluid system components, the RL3 is constructed from premium 316 stainless steel and is suitable for use with a wide range of aggressive media, including hydraulic fluids, process gases, and corrosive liquids. Its proportional actuation characteristic allows the valve to open gradually as inlet pressure rises above the set pressure, delivering stable, controlled relief flow and minimizing system shock. The RL3 is a compact, panel-mountable valve widely deployed in analytical instrumentation, sampling systems, hydraulic power units, and general industrial process circuits where reliable, repeatable pressure relief is critical to operational safety and system integrity.
