LUBRICATION PROCEDURES
The 1008A series adjustable port valves should be lubricated on a regular basis. Note that due to the possibility that a grease fitting can leak gas into the atmosphere, the 1008A series valves are no longer supplied with a grease fitting installed. When servicing valves, users must supply their own temporary grease fitting and greasing tools. TYPE OF LUBRICATION 1008A adjustable port valves are factory lubricated with lithium
WARNING: To prevent the possibility of personal injury or property damage, turn off electrical power, turn off gas to depressurize valve, and vent fluid to a safe area before ser- vicing valve. These valves do not come with grease fittings for field lubrica- tion. Users must supply their own temporary grease fitting and greasing tools. The valve bodies have a 1⁄8 " NPT pipe plug that needs to be removed and temporarily replaced with a grease fitting . When applying the lubrication to the valve core and curtain as- sembly, the curtain (valve port opening) should be fully closed. Before closing curtain, note existing valve curtain position. A good method of indicating initial curtain position is to count and record the number of turns required on the adjusting screw to fully close the curtain. Turning the adjusting screw back open the same number of turns will set curtain back to its initial posi- tion. To adjust curtain remove adjusting knob cover, slightly loosen packing nut, turn adjusting screw knob clockwise to open cur- tain or counterclockwise to close curtain (note that on 3⁄8 " and ½" sized valves, turn knob clockwise to close curtain or coun- terclockwise to open curtain). This raises or lowers the curtain in the core, altering valve port opening. After application of the lubricant, the valve core should be stroked fully open and closed several times and the curtain should be fully opened and closed before resetting back to the initial position to allow lubricant to be distributed evenly within the valve body. After servicing, always remove the temporary grease fitting and re-install the pipe plug using proper piping practice (i.e. pipe thread sealant). Always retighten the packing nut and replace the adjusting knob cover.
based #2 lubricant unless otherwise specified. Specifications for a typical lithium lubricant are: Consistency – #2 Dropping Point – 393 F Base – Lithium.
A few lubricants meeting the above specifications are Factran EP 2 lubricant distributed by BP Oil Co., Shell Oil Alvania #2, and Atlantic Richfield Litholine Industrial Grease #2EP. If some other lubricant is to be used, it is recommended that its specifi- cations should match those shown above. WARNING: Valves intended for oxygen service (1008A-C, 1010A- C series) use a special synthetic based Molylube PFET-2 lubricant designed specifically to be compatible with oxygen service. See 1008A-C and 1010A-C technical information. For steam applications (1008A-S & 1010A-S series) Fives uses a special silicone lubricant Dow Corning #111 compound. For applications with corrosive gases such as coke oven gas, we recommend lithium #2 complex grease . FREQUENCY It is recommended that 1008A series valves are lubricated at least three to four times per year. Frequency of lubrication depends entirely on the specific ap- plication, type, quality and composition of the fluid the valve is being used with, as well as frequency of operation, operating conditions including temperature, pressure and fluid velocity. It is possible that high velocities can carry away some of the lu- brication over time. All of these variables need to be considered when determining required lubrication. Applications using corrosive fluids may require monthly or even weekly lubrication . When used in steam service, adjustable port valves should be greased at 7 to 10 day intervals.
