About Air Preparation

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.

For Use With: Water
Temperature Range: See Table
Specifications Met:
Threaded—NPT Female Bronze Body Valves: CSA Certified
All Other Valves: ASSE 1003 Listed, CAN/CSA-B356, CSA Certified, IAPMO Listed

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. They also have an internal strainer to trap debris. Union fittings on both ends of the valves disassemble for easy valve installation and removal. All of these valves meet Canadian safety standards for pressure-reducing valves. Some also meet American and international plumbing safety and performance standards.

Valves with gauge ports let you attach a pressure gauge to measure the pressure flowing in and out of the valve.

Bronze valves are durable and have a long service life.
