Quiet Safety-Lockout Air On/Off Valves
The muffler on these valves reduces exhaust noise. A padlock (not included) locks the handle in the shut-off position to disconnect air tools safely. They comply with OSHA 29 CFR 1910.147 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.

Safety-Lockout Air On/Off Valves
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.
Valves that comply with OSHA 29 CFR 1910.147 meet standards for the control of energy sources that could injure workers.
