Stainless Steel L-O-X® Valves Energy Isolation Port Sizes ¼ thru 2 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. STANDARD SPECIFICATIONS: Ambient/Media Temperature: 40° to 175°F (4° to 80°C). Note: For lower temperature ratings, consult Ross. Flow Media: Compressed air, ltered; 5 micron recommended. Inlet Pressure: 0 to 300 psig (0 to 20.7 bar). Port Threads: NPT standard, BSPP. For BSPP threads, add a “D” prex to the model number, e.g., D1523A2004. Lock Hole Diameter: Port sizes 1/4 thru 2: 0.34 inch (8.64 mm). Length of Hole: Port size 1/4: 0.44 in (11.17mm). Port size 1/2: 0.47 in (11.93mm) Port size 1 and 2: 0.55 inch (13.97 mm). NOTE: Per specications and regulations, these products are dened as energy isolation devices, NOT AS EMERGENCY STOP DEVICES. Referenced Standards: All standards are subject to revision. Parties are encouraged to investigate and apply the most recent editions of the standards indicated below. OSHA 29 CFR 1910.147; CSA Z142-10 CSA Z460-05; ISO 13849-1; ISO 14118:2000 EN 1037; ANSI Z244.1- 2003(R2008) ANSI/PMMI B155.1- 2006, ANSI B11-2008 ROSS L-O-X® valves are energy isolation valves and are generally used as the rst valve in a line supplying compressed air to equipment. Air can be shut off by pushing the L-O-X® handle inward; downstream air is simultaneously exhausted through the L-O-X® exhaust por t. Many standards & regulations, e.g., OSHA, require that the valve be padlocked in this position to prevent handle from being pulled out inadvertently during maintenance and/or servicing. Easily identied by unique shape Corrosion-resistant stainless steel construction Reliable VITON seals withstand contaminant ingression Self-draining, washdown suitable design Trusted L-O-X® performance Lockable only in the OFF position Large exhaust port for rapid release of pressure Standard pressure sensing port with optional pressure switch or pop-up indicator • Simple push/pull of the large handle provides direct manual operation • Pressure sensing port allows installation of either the Pop-Up Indicator or Pressure switch (see page 2) to verify pressure downstream to the next obstruction is released. APPLICATIONS: • Food and Beverage • Pharmaceutical • Pulp and Paper • Chemical Processing • Oil and Gas • Off-shore Industries

Valve Operation VALVE OPEN When the handle is pulled out, supply air flows freely from inlet to outlet and flow to exhaust is blocked. A detent keeps the handle in the open position. The handle is not designed to be locked in this position, thereby providing for ready shut-off when necessary. VALVE CLOSED With a push of the handle inward, the flow of supply air is blocked and downstream air is exhausted via the exhaust port while servicing or maintaining machinery. Padlock the L-O-X® valve in this position OUT to prevent the handle from being pulled outward inadvertently to avoid potential...

Technical Specifications – RPB12 Overview of RPB12 Regulator Operation A Turning the adjusting knob / T-Handle (A) clockwise applies a load to control spring (B) which forces diaphragm (C) and valve poppet assembly (D) to move downward allowing filtered air to flow through the seat area (E) created between thepoppet assembly and the seat. “First stage filtration”. Air pressure supplied to the inlet port is directed through deflector plate (F) causing a swirling centrifugal action forcing liquids and coarse particles to the inner bowl wall (G) and down below the lower baffle (H) to the quiet...
