General
The following instruction are designed to assist in assembling as required on Flowserve FlowAct IG actuators.
This instruction does not include specific product design data. These are located at the corresponding data
sheet, calculation sheet, dimension sheet in the documentation. Procure the documents before you start
if this appears necessary. In Assembling Instructions can not be dealt with every conceivable situation
and installation options. It is expressly permitted only qualified stuff to work at FlowAct actuators who
are educated and trained at actuators and accessories. Review this bulletin prior to assemble the actuator.
Modifying this product, substituting non-factory parts other than outlined could drastically affect
performance and be hazardous to personnel and equipment. This manual should be used in conjunction
with applicable local and national laws.
WARNING
Failure to keep hands, hair, and clothing away from all moving parts when
operating the actuator can cause serious injury.
Apply appropriate personal protective equipment when working on the actuator to prevent hazards
arising from the operation. Protect yourself against scalds, cuts by protective clothing, gloves and
eye protection.
Actuators are provided for oil and grease-less service or oxygen service may only assembled in
clean rooms (ISO 14644 - ISO 8, US FED STD 209E - M 6.5, or equivalent) and in accordance with
the Flowserve Control Valves - Work Instruction T 007.
