1 Important Safety Procedures
Installation, adjustment, putting into service, use, assembly, disas-
sembly and maintenance of the Actuator is strictly reserved to quali-
ed personnel.
Before installation, operation and maintenance, read the relevant
sections of:
- This manual
- Quick Reference Guide: DOC.QRG.XL
Caution: Always disconnect the Air and Electrical supplies before
carrying out any form of maintenance on an Actuator.
Caution: When removing any ball valve or plug valve assemblies
from a pipe system, isolate the piping system on which the Actuator
is installed and relieve any media pressure that may be trapped in
the valve cavities before removing the Actuator for maintenance.
Caution: Always contain the Spring tension with HYTORK Retrac-
tor Rods as explained in Section 9 (Disassembly procedure). Follow
instructions for using the Retractor Rod carefully. Only HYTORK
manufactured or approved Retractor Rods are to be used for Spring
removal. As with any threaded tool that is frequently used Retractor
Rods should be checked to ensure that the threads are not worn or
damaged in any way and greased regularly. Any damaged or worn
Rods must not be used and must be destroyed.
Never attempt to ‘BLOW OUT’ the Pistons or the End caps from the
Actuator Body by using air pressure.
Never turn the stop screws completely out when the actuator is
under pressure
Numbers in brackets (#) refer to parts on the exploded view drawing
(Fig. 5).
All HYTORK XL Spares Kits are supplied with SAFEKEY assemblies
(13/14) cut to an exact length which will t the circumference of the
End Cap (21) when fully assembled into the Actuator. Any shortened
SAFEKEY must not be used. If in doubt contact Emerson Process
Management or your local HYTORK Stocking Distributor.
Read the relevant sections carefully before continuing.
1.1 Warehouse storage
HYTORK Actuators should be stored in a clean, dry warehouse, free
from excessive vibration and rapid temperature changes.
Actuators should not be stored on any oor surface.
1.2 On site storage
HYTORK actuators should be stored in a clean, dry warehouse, free
from excessive vibration and rapid temperature changes.
Prevent moisture or dirt entering the actuator. Plug or seal both air
connection ports.
Important! Failure to follow proper storage guidelines will void war-
ranty
1.3 Lifting instructions
Use lifting equipement as required by national or local legislation.
Use lifting straps to lift the assembly of actuator and valve.
Do not attach lifting straps to only the actuator, to lift the assem-
bly of actuator and valve.
