Product Overview
The SWAGELOK SS-RL3S6MM is a precision proportional relief valve engineered for fine-tuned pressure control in demanding industrial fluid and gas handling systems. Manufactured by Swagelok, a globally recognized authority in high-integrity fluid system components, this valve utilizes a spring-loaded, poppet-style relief mechanism that opens proportionally in response to upstream pressure, providing smooth and continuous pressure modulation rather than abrupt on/off venting. Constructed from 316 stainless steel with 6 mm Swagelok tube fitting end connections, the SS-RL3S6MM is designed for direct installation into process and pneumatic circuits where accurate overpressure protection, repeatable cracking pressure, and leak-tight sealing are critical. Its proportional actuation characteristic makes it particularly suited for analytical instrumentation, sampling systems, and hydraulic pilot circuits requiring gradual pressure relief and stable downstream regulation.

Engineering Features & Advantages
- Precision Performance: Proportional poppet actuation delivers smooth, gradual pressure relief with repeatable cracking pressure and minimal hysteresis, enabling accurate overpressure control in sensitive process and pneumatic circuits.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a 316 stainless steel body offering excellent corrosion resistance and long service life in aggressive media environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including genuine 6 mm Swagelok tube fitting geometry for leak-tight, tool-free installation.
Typical Industrial Applications
The SWAGELOK SS-RL3S6MM proportional relief valve is widely deployed in analytical instrumentation and sampling systems, process and pneumatic control panels, hydraulic pilot and pressure-holding circuits, and chemical injection or dosing skids. Its stainless steel construction and proportional relief behavior make it equally suitable for offshore, petrochemical, and pharmaceutical process environments where precise overpressure protection and clean fluid compatibility are mandatory.
