SMC Modular Compressed Air Regulators
Adjust and maintain the pressure of your compressed air. These regulators use joiner clamps (sold separately) to connect to other SMC units of the same series so you can customize your air preparation system. Install them in your air line after filters.
Relieving regulators exhaust when the downstream pressure exceeds the set pressure. Nonrelieving regulators don’t exhaust any downstream pressure. They’re often used to conserve air or to avoid contaminating a controlled area. To prevent pressure buildup, manually vent them or add a relief valve.
Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
Joiner clamps (sold separately) connect these regulators to other SMC modular components with the same series number, even if the pipe sizes are slightly different. They create compact, airtight connections that are easy to swap out. They come with mounting brackets.

Compressed Air Regulators for Double-Acting Cylinders
When your double-acting cylinder sends high-speed air in reverse, a check valve inside these regulators blocks it. They maintain compressed air at the pressure you set, even when the exhaust ports on your control valve can’t keep up with reverse flow. Install them in your air line after filters.
Relieving regulators exhaust when the downstream pressure exceeds the set pressure.
Nonrelieving regulators do not exhaust excess downstream pressure.
