About Pressure-Relief Valves

Compressed Air Regulators

Adjust and maintain the pressure of your compressed air. Install regulators in your air line after filters.

Relieving regulators exhaust when the downstream pressure exceeds the set pressure.

Mounting brackets allow you to attach the regulator to a wall or equipment.

Safety-Lockout Air On/Off Valves

Brass Body

A padlock (not included) locks the handle of these valves in the shut-off position. When valves are closed, the exhaust port vents air pressure so you can disconnect air tools safely. They meet OSHA lockout requirements to maintain safety and control in a compressed air system.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Metering Valves for Abrasive Blasting

Control the amount of abrasive material that your blast hose releases by using these valves, which have a knob for adjusting the size of their opening. To help you find the right size quickly, there’s a virtual position indicator under the knob. Their stainless steel body resists wear and won’t rust in damp locations. Abrasive material passes through the valve’s base, so for extreme durability the base is made of steel and the seat and gasket are polyurethane. When it’s time to remove debris from these valves, you don’t have to take them apart because they have a cleanout port. To eliminate air leaks, their bolt holes are sealed.
