MODEL: SPN 032, 050, 063, 075, 085, 100, 115, 125, 145, 160, 180, 200, 240, 265
WARNING AND SAFETY INSTRUCTIONS:
1. Read this Installation, Operation & Maintenance manual before using the actuator.
2. Sharpe Valves cannot anticipate all of the situations a user may encounter while installing and using the
SPNII Actuator. The user must know and follow all applicable industry specifications on the safe
installation and use of these actuators. Only qualified personnel or technicians who are trained for
maintenance work and have read the instructions are to assemble and disassemble the actuator.
Misapplication of the product may result in injuries or property damage.
3. Before operating an actuator which is connected to a valve in the pipeline, make sure you know the
valve function.
4. Make sure the actuator is not connected to the air supply or electrical system before attempting to do
any maintenance.
5. Before removing the actuator from the valve, always make sure the line has been depressurized and
drained. Cycle the valve a few times to relieve any pressure that could be trapped in the body cavity.
6. Use only Sonic Torque components and spare parts supplied in the repair kits.
7. Do not use air pressure to remove actuator pistons when covers have been removed.
8. Do not leave any grip key or shaft connection attached to the actuator, or try to manually operate the
actuator while it is still connected to the air supply.
9. The user must follow and observe any national or local safety law imposed for
for his system.
STORAGE
The Sonic Torque SPNII Actuator has been packaged to provide protection
during shipment and storage. It is however, possible that the actuator can be
damaged during transport. Inspect actuator for shipping damage prior to storage.
Keep the actuator in their original boxes and store indoor in a clean dry
environment until ready for use. Keep plastic plugs in the air ports to prevent
liquids or other materials from entering the actuator during storage. It is
recommended to stroke them periodically to prevent setting of seals.
LUBRICATION:
The actuators are pre lubricated from the factory and under normal operating conditions
do not require re-lubrication. In the event of actuator maintenance it is recommended
to use the following lubricants:
For NBR O-rings use EP1. The lubricant is suitable for use from -20ºC to +80ºC
