Regulations for Workplace Safety The Occupational Safety and Health Administration (OSHA) regulation (29 CFR 1910.147) details safety requirements for the control of hazardous energy during the maintenance and servicing of machines and equipment. WHAT DOES THE RULE REQUIRE? In general terms, the rule requires that energy sources (pneumatic, electric, hydraulic, etc.) be shut off or disconnected while equipment is being serviced.
How Users of Pneumatic Equipment Can Comply with OSHA Rules Here’s how our famous L-O-X® valve helps... ROSS EEZ-ON® Valves Also Add to Plant Safety A ROSS EEZ-ON® valve is designed to allow a gradual buildup of downstream air pressure before opening the line to full air flow. This gradual pressure buildup allows cylinders and other work elements to move slowly and more safely into their normal working positions before full line pressure buildup is applied.
Series 15 L-O-X® Valves with EEZ-ON® Operation Combines L-O-X® Shut-off with EEZ-ON® Gradual Starts VALVE OPERATION 2 12 3/4 - 11/4 3/8 - 3/4 10 1 3 The L-O-X® with EEZ-ON® operation valve combines shut-off certainty with gradual pressurization upon start-up. Special labels and adjustment screw indicates EEZ-ON® function.
Series 15 Manual L-O-X® Valves • Reliable, Low-Cost Control • 1/4 to 3/8 Ports 2 12 3 10 VALVE OPERATION VALVE CLOSED 1 When the red handle is pushed inward, the flow of supply air is blocked and downstream air is exhausted via the exhaust port. While servicing or maintaining machinery, the L-O-X® valve should be padlocked in this position to prevent the handle from being pulled outward inadvertently where potential for human injury exists. Manual L-O-X® valve shown padlocked in closed position.
Series 15 Manual L-O-X® Valves • Reliable, Low-Cost Control • 3/8 to 11/4 Ports VALVE OPERATION 2 12 3/8 - 3/4 3/4 - 11/4 3 VALVE CLOSED With a short push of the red handle inward, the flow of supply air is blocked and downstream air is exhausted via the exhaust port at the bottom of the valve. The L-O-X® valve should be padlocked in this position to prevent the handle from being pulled outward inadvertently where potential for human injury exists or while servicing machinery.
Series 15 Manual L-O-X® Valves 2 12 • Reliable, Low-Cost Control • 11/2 and 2 Ports 10 VALVE OPERATION 1 3 Manual L-O-X® valve shown padlocked in closed position. The valve can only be locked in the closed position. Push/pull operation - Push the handle inward to exhaust downstream air (lockable in this position). Pull the handle outward in to supply air downstream. 11/2 and 2 The ROSS LOX® 1-1/2 and 2 inch port size are the newest addition to ROSS’ renowned family of safety-related products.
Series 27 Piloted Valves with L-O-X® Control • Reliable, Low-Cost Control • 3 Inch Port 3" NPT INLET 3" NPT OUTLET 3 Inch L-O-X® Valve for Lockout Five good reasons to equip your pneumatic systems with our energy isolating L-O-X® valve: Effectiveness: A L-O-X® valve not only isolates the equipment by shutting off air supply, it exhausts stored or residual air immediately from downstream. Ease of Use: Air shutoff is simple; just push in the bright red handle.
Series 27 Manual Piloted Valves with L-O-X® Control Port Sizes up to 21/2 for Larger Systems VALVE OPERATION Y3 2 3 1 Operated just like the smaller manual L-O-X® valves shown on page 5. The position of the red handle indicates instantaneous full flow pressurizing or exhausting capability. Following any FRL components, an energy isolation valve is usually the first valve in the line supplying compressed air to equipment.
Series 27 Solenoid Piloted Valves with L-O-X® Control Remote Control in a Full Range of Valve Sizes 3 1 3 Y VALVE OPERATION 3 Y 2 The position of the red handle indicates instantaneous full flow pressurizing or exhausting capability. Following any FRL components, an energy isolation valve is usually the first valve in the line supplying compressed air to equipment. The energy isolation valve should provide a quick means of shutting off the supply of air and exhausting the downstream lines.
Series 27 EEZ-ON® Valves A Gradual Start-up for Pneumatic Circuits 2/2 EEZ-ON® Valves VALVE OPERATION ADJUSTING NEEDLE AIR PRESSURE TO INLET When air pressure is first applied to the inlet, air flow to the piston is restricted by the adjustable needle in the delay orifice. Downstream air pressure gradually builds up at a rate determined by the setting of the adjustable needle. 2 1 The EEZ-ON® valve is designed to allow a gradual buildup of downstream air pressure before opening to full air flow.
Series 27 EEZ-ON® Valves Gradual Start-up plus Pressure Controlled and Line Exhaust 3/2 EEZ-ON® Valves Internal Pressure Controlled PILOT VALVE VALVE OPERATION Pilot not energized Pilot air is blocked by the pilot. Any downstream pressure forces piston B (which slides on the valve stem) upward. This opens the exhaust port and vents the downstream line. Solenoid Pilot Controlled The 3/2 EEZ-ON® valve provides the same gradual pressure buildup as the 2/2 EEZ-ON® valves described on page 11.
Series 27 Manual L-O-X® Valves with EEZ-ON® Operation These unique valves give pneumatic circuits the soft start-up of the EEZ-ON® valves plus the lockout and exhaust capabilities of L-O-X® valves. They are available with either solenoid or air pilots. Blue handle indicates that EEZ-ON® function is included (L-O-X® valves with red handles do not have the EEZ-ON® function).
Right-Angle EEZ-ON® Valves Port Mounted 2-way Normally Closed EEZ-ON® EEZ-ON® Valves are used to gradually apply air pressure downstream when supply is initially applied. Select the model you need to operate with supply pressure at either port 1 or port 2.
