General Maintenance
Inspection
Inspection of the components listed below should be done during regular servicing intervals. Before removing the equipment from
the process line, please do the following:
• Clean the process line completely to remove any product that may be harmful if coming in contact with a person.
• Prior to loosening the ferrule clamp bolts (with valve in the open position):
- Depressurize the piping at the valve.
- Drain tubing run as much as possible.
- Cycle the valve to drain any trapped uid from the body cavity. The valve should be left fully open or fully closed.
- Vent the line to relieve any pressure.
• Close valve, then:
- Disconnect all air and electrical power from the actuator, solenoid valve, switch box (if applicable), and tag for reinstallation.
- Remove the actuator, solenoid valve, and switch box, if any.
- Loosen clamps to decompress valve gasket seals.
- Secure necessary lifting equipment to valve assembly if necessary.
- Remove clamps and valve from between ferrule.
- Close any isolation valves on either side of the equipment being serviced.
- Once the equipment has been removed from the line, cap the lines that were connected to the piece of equipment being
serviced to prevent any foreign material from entering the line.
Cleaning
IMPORTANT: Before operating the equipment during formal production, please follow the guidelines listed below to ensure that
your equipment is clean and ready for service.
• Ensure that the equipment is installed in a proper orientation to allow the equipment to be cleaned and drained properly.
Reference the installation and startup section of the manual for orientation guidelines.
• Flush the equipment with an appropriate cleaning agent to remove any residue that may be on the equipment from shipping.
IMPORTANT: DO NOT use cleaning agents that will attack stainless steel or the elastomers that were supplied with the valve.
If you are unsure what elastomer is used in the valve, reference the part number key in this manual to make
the determination.
• Follow any MSDS instructions for proper use or handling of cleaning agents.
• Flush the equipment to remove any soiling from the product contact components. Depending on the process, there may be varying
amounts of soiling. Cleaning times and cleaning agent concentrations will vary depending on the product being processed. It is the
responsibility of the operator to determine and adjust these cleaning specications as necessary.
• The equipment should not be allowed to sit with product present in it for extended periods of time. Equipment should be cleaned
immediately after processing is complete.
Components to be inspected:
• Item 1: valve seats and seals
• Item 2: valve ball
• Item 3: valve ends
Any components that show signs of severe wear or damage should be replaced during the scheduled maintenance time for the
equipment. Please refer to the assembly and disassembly section of this manual for proper instructions on removing and replacing
any worn or damaged components. Replacement components and repair kits can be found in the BOM or repair kits section of this
manual.
Manual Cleaning (COP)
1. Refer to the disassembly section of the manual and follow instructions to remove all product contact components.
2. Inspect the product contact components of the equipment for any signs of possible damage. Replace components as
necessary (see the equipment BOM in this manual for replacement component part numbers).
3. Clean all surfaces of the product contact components by manually brushing in a bath of cleaning solution (acid detergents or
simple alkaline soda type detergents).
4. After cleaning, rinse all components thoroughly with water.
5. Refer to the assembly section of the manual and follow instructions to properly reassemble the equipment.
