Maintenance
Maintenance Intervals
Maintain adequate stock of replacement parts. See the items in
bold beginning on page 48 for recommended spare parts.
Maintenance intervals should be determined by the user and spe-
cific application, based on the following conditions:
• Daily operation period
• Switching frequency
• Application parameters such as temperature, pressure, and
flow
• Product type
Inspection
Inspect the following on a regular basis:
• Actuator connections for air leaks
• Valve body and stem o-rings
• Valve seats (If leakage occurs, see “Troubleshooting” on
page 87)
• Pneumatic connections:
- Air pressure at supply connection
- Air lines for kinks and leaks
- Threaded connections for tight fit
- Threaded stress relief for tight fit
• Electrical connections secure on the control module:
- Wire connections tight on the terminal strip
- Clean air filter at regular intervals.
Lubrication
No lubrication is required other than as noted in the disassembly
and assembly procedures. (Use food grade non-petroleum (sili-
cone) grease on seals and o-rings.)
Apply Bostik Never-Seez
®
White Food Grade with PTFE or
equivalent to all bolts and threaded stem parts.
Cleaning
Avoid splashing any liquid into the air vent of the actuator during
clean up.
Cleaning-In-Place (CIP)
NOTE: Actuate each valve a minimum of
twice each cycle to ensure effective
cleaning and sanitizing.
CIP methods can be used to clean installed automatic valves
without disassembly. Select methods based on the specific
requirements of sanitarians and each application. Check with
local chemical suppliers for the most effective cleaning agents
and procedures.
Do not put a hand into the yoke or body
of a pneumatically actuated valve.
