Manual Control Reversing Valve — SH402 / SH403 Key benefits Precise manual control: Provides reliable twoposition, fiveway directional control for systems that require manual switching of flow. Simple, safe resetting: SH403 includes a manual reset/hand control for clear, intentional switching and reset operations. Reduces downtime: Manual operation and reset capability make the valve useful for testing, maintenance, and emergency override without complex tooling or power. What this valve does Twoposition, fiveway reversing action to change flow direction or switch between two operating states. Manual operation for direct human control and clear tactile feedback. SH402 and SH403 models, with SH403 offering the reset/hand control feature identified in the model name. Key attributes Functionality: Manual reversing valve, twoposition, fiveway. Models: SH402 and SH403 (SH403 includes the reset hand control feature). Operation: Handoperated manual control with explicit reset capability on SH403. Application scope: Intended for systems that need manual directional control of air or fluid flow and a straightforward manual reset/override. Typical use cases Manual direction change for doubleacting actuators during commissioning or setup. Isolation and safe manual control during maintenance and testing of directional control circuits. Emergency or temporary manual override of automated directional control in production lines or pneumatic systems. Why choose SH402 / SH403 Direct, intuitive manual operation reduces reliance on electrical or pilot signals when manual intervention is required. Clear model distinction allows selection between standard manual reversing (SH402) and manual reversing with reset/hand control (SH403). Practical for maintenance teams, test benches, and any application where a simple, reliable manual reversing valve is needed. Ordering information Select model SH402 for the manual twoposition fiveway reversing valve. Select model SH403 when a manual reset/hand control feature is required (model name indicates reset hand control). For installation and system compatibility, use the valve where twoposition, fiveway manual directional control and, if needed, manual reset functionality are required.
