Roller
Port size: 1/4.
Operators: toggle lever, pushbutton, plunger, roller, one-way roller. 2-way or 3-way normally closed design.
Dual mounting flanges.
Pneumatic equipment should be installed only by persons trained and experienced in such installation.
Cam Valves: To operate properly and avoid damage to the valve, cam operators must be moved by the operating cam only within the following limits:
Plunger: 0.07 to 0.25 inch
Roller: 0.10 to 0.29 inch
One-way roller: 0.05 to 0.10 inch
Air Lines: Before installing the valve in your system, the air lines must be blown clean of all contaminants. It is recommended that an air filter be installed in the circuit.
Valve Inlet (Port 1): Be sure the inlet line is of adequate size and does not restrict the air supply because of a crimp in the line, sharp bends or a clogged filter element.
Valve Outlet (Port 2): For best response and control of the mechanism being operated by the valve, locate the valve as close as possible to this mechanism. The lines must be of adequate size and free of crimps and sharp bends.
Valve Exhaust (Port 3): Exhaust of 3-way valves is unported.
Operating Pressures and Temperatures: Allowable ranges are shown under STANDARD SPECIFICATIONS on page 3.
Exceeding these values can shorten valve life.
Pipe Installation: To install pipe or fittings in the valve ports, engage the pipe or fitting one turn, apply thread sealant (tape not recommended), and tighten pipe or fitting. This procedure will prevent sealant from entering and contaminating the valve.

VALVE MAINTENANCE
Pneumatic equipment should be maintained only by persons trained and experienced in the maintenance of such equipment.
Supply Clean Air. Foreign material lodging in valves is a major cause of breakdowns. The use of a 5-micron-rated air filter located in the circuit is strongly recommended. The filter bowl should be drained regularly, and if its location makes draining difficult, the filter should be equipped with an automatic drain.
Check Lubricator Supply Rate. A lubricator should put a fine oil mist into the air line in direct proportion to the rate of air flow. Excessive lubrication can cause puddling in the valve and lead to malfunctions. For most applications an oil flow rate in the lubricator of one drop per minute is adequate.
(Note that this valve itself does not require air line lubrication, but some optional adaptors do, i.e. air index, etc.)
Compatible Lubricants. Although this valve does not require air line lubrication, it may be used with lubricated air being supplied to other mechanisms. Some oils contain additives that can harm seals or other valve components and so cause the valve to malfunction. Avoid oils with phosphate additives (e.g., zinc dithiophosphate), and diester oils; both types can harm valve components. The best oils to use are generally petroleum base oils with oxidation inhibitors, an aniline point between 180°F (82°C) and 220°F (104°C), and an ISO 32 or lighter viscosity.
Some compatible oils are listed above at the right. These oils, although believed to be compatible, could change without notice because manufacturers sometimes reformulate their oils. Therefore, use oils specifically compounded for air line service. If it is a synthetic oil, contact the oil manufacturer for compatibility information.

Cleaning the Valve. If the air supplied to the valve has not been well filtered, the interior of the valve may accumulate dirt and varnish which can affect the valve’s performance. A schedule should be established for cleaning all valves, the frequency depending on the cleanliness of the air being supplied.
To clean the valve use any good commercial solvent.
Do not scrape varnished surfaces. Also do not use chlorinated solvents or abrasive materials. The former damages seals, and abrasives can do permanent damage to metal parts. Before reassembling the valve, lubricate all sliding surfaces with a grease such as Mobilgrease 28.
Replace Worn Components. In some cases it is not necessary to remove the valve from its installation for servicing. However, turn off the electrical power to the valve, shut off the air supply, and exhaust the air in the system before beginning any disassembly operation.
Service kits for these valves are listed on page 3.

CAUTIONS And WARNINGS
PRE-INSTALLATION or SERVICE
1. Before servicing a valve or other pneumatic component, be sure that all sources of energy are turned off, the entire pneumatic system is shut off and exhausted, and all power sources are locked out (ref:
OSHA 1910.147, EN 1037).
2. All ROSS ® products, including service kits and parts, should be installed and/or serviced only by persons having training and experience with pneumatic equipment. Because any installation can be tampered with or need servicing after installation, persons responsible for the safety of others or the care of equipment must check every installation on a regular basis and perform all necessary maintenance.
3. All applicable instructions should be read and complied with before using any fluid power system in order to prevent harm to persons or equipment. In addition, overhauled or serviced valves must be functionally tested prior to installation and use. If you have any questions, call your nearest ROSS location listed in the table below.
4. Each ROSS product should be used within its specification limits.
In addition, use only ROSS parts to repair ROSS products.
WARNINGS: Failure to follow these directions can adversely affect the performance of the product or result in the potential for human injury or damage to property.
FILTRATION and LUBRICATION
5. Dirt, scale, moisture, etc. are present in virtually every air system.
Although some valves are more tolerant of these contaminants than others, best performance will be realized if a filter is installed to clean the air supply, thus preventing contaminants from interfering with the proper performance of the equipment. ROSS recommends a filter with a 5-micron rating for normal applications.
6. All standard ROSS filters and lubricators with polycarbonate plastic bowls are designed for compressed air applications only. Do not fail to use the metal bowl guard, where provided, to minimize danger from high pressure fragmentation in the event of bowl failure.
Do not expose these products to certain fluids, such as alcohol or liquefied petroleum gas, as they can cause bowls to rupture, creating a combustible condition, hazardous leakage, and the potential for human injury or damage to property. Immediately replace a crazed, cracked, or deteriorated bowl. When bowl gets dirty, replace it or wipe it with a clean dry cloth.
7. Only use lubricants which are compatible with materials used in the valves and other components in the system. Normally, compatible lubricants are petroleum based oils with oxidation inhibitors, an aniline point between 180°F (82°C) and 220°F (104°C), and an ISO
32, or lighter, viscosity. Avoid oils with phosphate type additives which can harm polyurethane components, potentially leading to valve failure which risks human injury, and/or damage to property.
AVOID INTAKE/EXHAUST RESTRICTION
8. Do not restrict the air flow in the supply line. To do so could reduce the pressure of the supply air below the minimum requirements for the valve and thereby cause erratic action.
9. Do not restrict a valve’s exhaust port as this can adversely affect its operation. Exhaust silencers must be resistant to clogging and must have flow capacities at least as great as the exhaust capacities of the valves. Contamination of the silencer can result in reduced flow and increased back pressure.
WARNINGS:
ROSS expressly disclaims all warranties and responsibility for any unsatisfactory performance or injuries caused by the use of the wrong type, wrong size, or an inadequately maintained silencer installed with a ROSS product.
POWER PRESSES
10. Mechanical power presses and other potentially hazardous machinery using a pneumatically controlled clutch and brake mechanism must use a press control double valve with a monitoring device. A double valve without a self-contained monitoring device should be used only in conjunction with a control system which assures monitoring of the valve. All double valve installations involving hazardous applications should incorporate a monitoring system which inhibits further operation of the valve and machine in the event of a failure within the valve mechanism.
ENERGY ISOLATION/EMERGENCY STOP
11. Per specifications and regulations, ROSS L-O-X ® valves and L-O-X ® valves with EEZ-ON ® operation are defined as energy isolation devices, NOT AS EMERGENCY STOP DEVICES.
