All globe valve/direct coupled actuator linkages shall
have an all metal housing. All linkage drive
mechanism designs shall have a self-lubricating
rack-and-pinion constructed of powdered metal and/
or steel. The linkage shall include an adjustable
manual override handle that can be removed without
affecting linkage operation.
All linkage models shall be able to withstand a
minimum torque of 300 lb-in on the pinion without
failure, for the rated life cycle of the actuator used.
Minimum width of rack and pinion gears shall be 3/4
in. A roller bearing directly opposing the pinion shall
back-up the rack. Rack attachment to the valve stem
shall not be threaded.
The linkage shall require no disassembly or gear
adjustment before, or during installation. The linkage
shall be designed such that the actuators can be
mounted at various orientations for installation
flexibility with limited space requirements. All
linkages and actuators must be manufactured by the
same company under ISO 9001 International Quality
Control Standards.
