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.

Air On/Off Valves
Turn airflow on and off with these valves. They have two balls to independently shut off airflow to one of two outlets from a single source. When closed, they vent air pressure to the atmosphere so you can disconnect air tools safely.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Timer-Operated Air On/Off Valves
Install these valves on your air storage tank outlet—at the end of the day, they automatically close to save energy. While in the off position, the tank stays pressurized so the compressor doesn't run when you don't need it to, even if there are small leaks from pipe fittings, drip legs, and other downstream connections. Also known as solenoid valves, these valves actuate when voltage is applied to the electrical connection. They operate on a timer that can be programmed to work with a regular schedule, but they also have a manual override if your schedule changes. They gradually open to prevent system damage from suddenly starting flow.

Air Signal On/Off Valves
When system pressure reaches the maximum, these valves open and send an air signal to turn on a downstream device such as a discharge valve or throttle. They close and send a signal to turn the device off when pressure drops.
