SMC Corporation US4436 Depressurization Air Solenoid Valve

SMC US4436 is a depressurization air solenoid valve designed to vent compressed air from a pneumatic line, enabling rapid depressurization for safe shutdowns and reset sequences in automation equipment. Marketed under part number 275059, this 4-pin solenoid valve is commonly configured with a 4-pin male electrical connector and pre-attached exhaust components, including mufflers and push-in fittings that simplify installation in compact control lines. The unit is intended for use with clean, dry air in standard industrial pneumatic circuits to provide reliable venting when the valve actuates. Typical deployments include safety depressurization in clamping devices, end-of-arm tooling, grippers, and other automation components where controlled venting is required to ensure safe hand-off or tool reset. The US4436 series from SMC embodies a compact footprint and compatibility with common valve manifolds, enabling straightforward replacement or upgrade within established SMC lineups.
