5.2 Minimum Lubricant Qualities Required
The standard lubricants used by Limitorque have been proven to be extremely reliable over
years of service. Limitorque does not recommend a particular lubricant substitute for the
standard lubricants; however, Limitorque does require the following lubricant qualities as a
minimum.
The lubricant must
• Contain an “EP” additive.
• Be suitable for the temperature range intended.
• Be water and heat resistant and non-separating.
• Not create more than 8% swell in Buna N or Viton.
• Not contain any grit, abrasive, or fillers.
• Be slump-resistant; prefer NLGI-0 grade.
• Not be corrosive to steel gears, ball, or roller bearings.
• Have a dropping point above 316°F for temperature ranges of -20°F to +150°F (-28°C
to 65°C).
5.3 Disassemble and Reassemble
a WARNING: Possible Hazardous Voltage. If WTR is mounted on an electric actuator,
turn power OFF before disassembling the WTR to prevent accidental start-up while
disassembling.
a WARNING: Potential High Pressure Vessel. Before removing or disassembling your
actuator, ensure that the valve or other actuated device is isolated and is not under
pressure.
