2 VALVES VAL-224 For further information www.norgren.com Fluids Filtered and lubricated compressed air or vacuum. Prospector poppet valves with A1, AA, or A4 air operators or with C, D, F, or X series solenoid operators may be used with filtered, non-lubricated compressed air or vacuum, although tests indicate that service life will be reduced. Valves with other operators must not be used in non-lubricated service. Seal Compatibility Prospector poppet valve seals are compatible with most good quality O-ring lubricants, including: DC BR-2+ grease (Dow Corning) DC 44 grease (Dow Corning) Magnalube G (Saunders Industries) Non-detergent mineral based oil such as Mobil DTE light oil. Poppet valve seals are not compatible with WD-40 or commonly used deicer fluids. Consult factory to verify compatibility of lubricants or fluids not listed above. Valve Exhaust The valve exhaust port must not be restricted with anything more than a muffler or equal pipe size (most exhaust ports are larger than the inlet port). Back pressure on the exhaust side of the valve poppets can, under some conditions, result in failure to operate. If exhaust is to be piped away, piping should be installed horizontally ar oat a downward angle from the valve to provide drainage an minimize sludge formation. Use of Speed Controls Speed controls may be installed in the exhuast port on Norgren 3-port/2-position multi-direction popped valves. Note: On all other poppet valves, speed controls should only be installed in the air line between the valve and the air- operated device and as close as possible to the device. Vacuum Service Valves that can be used in vacuum service are inentified by a "J" in the 6th position of the model number. For on-off application of vacuum, use a normally closed 2-port/2- position (2-way) valve. Connect the vacuum to the inlet port. When the valve is actuated, vacuum will be applied to the outlet port. For selecting alternately between vacuum and pressure, use a normally open 3-port/2-position (3-say) valve. Connect the vacuum to the exhaust port and vent the inlet port. When the valve is actuated, vacuum will be applied to the outlet port. In addition, 4-port/2-position (4-way) valves can be connected the same way as 3-port/2-position (3-way) valves for selectin alternately between vacuum and pressure or vacuum and vent. That is, connect the vacuum to the exhuast port and pressure or vent to the inlet port. When the valve is actuated, the cylinder ports (outlets) will be alternately switched between vacuum and pressure or vacuum and vent.
