The Swagelok 3-Way Valve Assembly (SS-41GXS2-51S) offers precise flow diversion and isolation in demanding industrial environments. Constructed from 316 stainless steel, this valve provides excellent corrosion resistance, chemical compatibility, and pressure integrity for critical process streams.

This configuration includes the Model 151-SR spring-return pneumatic actuator, providing fail-safe functionality in the event of air supply loss. Its 180° actuation travel enables smooth switching between two flow paths, making it ideal for sample systems, analyzer streams, bypass functions, and utility control circuits.

With a pressure rating up to 2500 PSIG @ 100°F, the SS-41GXS2-51S valve maintains robust performance under elevated pressure conditions, while its 1/8″ tube connections support compact system integration, particularly in panel-mounted instrumentation.
