Product catalog summary
Introduction: The document introduces ROSS L-O-X® valves, which are energy isolation devices used in compressed air systems. These valves are not emergency stop devices but are designed to isolate energy during maintenance.
Specifications: The valves operate within an ambient/media temperature range of 40° to 175°F (4° to 80°C) and can handle inlet pressures from 0 to 300 psig (0 to 20.7 bar). They are compatible with NPT and BSPP port threads, with specific model numbers for each type.
Features: Key features include corrosion-resistant stainless steel construction, VITON seals, a large exhaust port for rapid pressure release, and a lockable handle in the OFF position. The valves are designed for easy manual operation with a push/pull handle mechanism.
Standards and Regulations: The valves comply with various standards such as OSHA 29 CFR 1910.147, CSA Z142-10, and ISO 13849-1, among others. These standards ensure safety and reliability in industrial applications.
Applications: The valves are suitable for industries like food and beverage, pharmaceuticals, pulp and paper, chemical processing, oil and gas, and offshore industries.
Valve Operation: The valve can be locked in the closed position to prevent accidental operation during maintenance. The handle must be pushed inward to shut off air supply and exhaust downstream air.
Technical Specifications: Detailed specifications for various port sizes are provided, including dimensions, weight, and average CV values for different models.
Accessories: The document lists accessories such as stainless steel mufflers and RPB12 series stainless steel filter/regulators, which are designed to handle corrosive environments and provide precise regulation.
Warnings and Cautions: Users are cautioned against exceeding maximum pressure ratings and are advised to ensure air is dry enough to prevent ice formation at low temperatures.
Contact Information: Contact details for ROSS Controls offices worldwide are provided for customer service and technical support.

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 for...

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 zone....
