Storage Store valve in a properly sealed bag and in a dry, cool environment, avoiding moisture and extreme temperature conditions and any possible contamination. Valves can be stored for an indefinite period of time before commissioning into service. However, it is always good practice and is highly recommended that, before commissioning any valve into service that the valve be thoroughly inspected for proper functionality and adequate lubrication. Valves stored in excess of 6 months will likely require re-lubrication. To inspect valve, manually adjust the curtain adjusting screw opened and closed. Open and close the core by stroking valve 100% while visually inspecting the internals through the inlet and outlet ports of the valve to assure proper operation and observe adequate lubrication. Address any issues that may be observed before commissioning into service.
To adjust curtain, remove adjusting knob cover, slightly loosen packing nut, turn adjusting screw knob clockwise to open curtain or counterclockwise to close curtain (note that on 3⁄8 " and ½ " size valves, turn knob clockwise to close curtain or counterclockwise 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 lubrication to be distributed evenly within the valve body. Always retighten the packing nut and replace the adjusting knob cover after servicing. If a grease fitting was used, it should be removed after servicing and replaced with a cleaned 1⁄8 " NPT pipe plug using proper piping practice (i.e. oxygen- approved thread compound such as LA-CO Oxytite pipe thread sealant with PTFE for oxygen. North American part number R002-9820). Frequency Frequency of lubrication depends entirely on the specific application, type, quality and composition of the O ² gas, as well as frequency of operation, and operating conditions including temperature, pressure and fluid velocity. We recommend that it is good practice to lubricate "at least" 4 times per year. It is possible that high velocities can carry away some of the lubrication over time. All of these variables need to be considered when determining required lubrication frequency. In rare cases some applications require monthly or even weekly lubrication to help reduce servicing for repair of the valve.
To order, specify: R400-6415
Per fluoro polyether grease for oxygen service (14oz. tube)
WARNING: If lubrication is desired, servicing must be performed by a trained and approved technician familiar with oxygen service safety requirements.
