Applications
Lockout valves are installed in pneumatic drop legs, or individual pneumatic control lines. In accordance with OSHA procedures, lockout valves are used during maintenance and service procedures of pneumatically (air) operated equipment. Prior to servicing, the red handle is pressed inward, blocking pressure and relieving all downstream air pressure. A padlock is installed through the locking hasp, preventing accidental actuation during the maintenance procedure. Following maintenance, the padlock is removed and the red handle is pulled outward, returning air pressure to the system.
Placement of Lockout Device
Operation
Valve Closed
With a short inward push of the red handle, the flow of supply air is blocked from the outlet port. Downstream air flows from outlet to exhaust port. The valve must be padlocked while in this position during maintenance to prevent it from being inadvertently pulled outward and creating the potential for injury to people or machinery.

The valve must be padlocked while in this position during maintenance to prevent it from being inadvertently pulled outward and creating the potential for injury to people or machinery.
Valve Open
When the red handle is pulled out, supply air flows freely from inlet to outlet, and flow to the exhaust port is blocked. A detent keeps the handle in the open position. The handle is not designed to be locked in the open position so that the valve is always ready for shutoff.
