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. (For complete Lockout / Tagout procedures, consult OSHA Standard 9 FR Part 90 in U.S. Federal Register/Vol. 54 No. 69, Friday, September, 989 / Page 6644.)

In accordance with OSHA procedures, EZ valves are used during maintenance and service procedures of pneumatically (air) operated equipment. Prior to servicing, the blue 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 blue handle is pulled outward, gradually returning air pressure to the system.

5 atalog 9W-BJ-6 (Revised 0/5/04) Technical Information EZ Series, Lockout Valve Operation, Specifications & Ordering Info Operation Normal Machine Operation Valve Open When the blue handle is pulled outward, the adjustable needle valve (accessed through the top of the handle) setting determines the rate of pressure buildup. When downstream pressure reaches the full flow described in the specifications below, Inlet Port is open to outlet Port. Exhaust Port is blocked. Lockout Operation Valve losed When the blue handle is pushed inward, the Inlet Port is blocked. Downstream air is exhausted through Exhaust Port. Open Pressure Building Up Open Full Flow losed Specifications Operating Pressure Range 0 to 50 PSIG ( to 0 bar) Open to Full Flow: Inlet Pressure - 5 PSIG (.7 bar) Operating Temperature Range (Ambient) 40 F to 75 F (4 to 80 ) Lubrication For best results and service life, use clean, moisture free, lubricated air.

EZ0ANBA Schematic FRL Main Air Pressure To Requirement 0 To Requirement Figure Lockout Valves Shown In The Passing ondition 0 Friday, September, 989 the Occupational Safety and Health Administration (OSHA) passed a standard, 9FR Part 90, requiring certain lockout and / or tagout procedures for the control of a hazardous energy source. This standard addresses practices and procedures that are necessary to disable the release of potentially hazardous energy while maintenance and servicing activities are being performed. Tagout refers to the use of tags to warn workers when equipment using potentially hazardous energy is being serviced. Lockout is the procedure which ensures that all power to a piece of equipment is isolated, locked or blocked and dissipated using a method that cannot be readily removed to bypassed. Dissipation means stored energy at the equipment is brought to a neutral state. This standard is expected to save 0 lives and prevent 60,000 accidents a year. This OSHA Standard became effective October, 989. A typical application (Figure ) shows a main lockout valve mounted in the main drop leg, before the split to machine functions. Additional lockout valves can be used to isolate individual control lines. Before servicing, the valve can be actuated and locked to isolate downstream from pressure, and exhaust downstream to atmosphere thus making equipment safe for maintenance. To reference this standard see the U.S. Federal Register / Vol. 54, No. 69 / Friday, September, 989 / Page For copies of this standard, contact U.S. Department of Labor, Occupational Safety and Health Administration, Office of Publication, Room N0, Washington, D 00, (0) Wilkerson Operations
