Preparations before Mounting
All O-rings and X-rings are laid in hydraulic oil before mounting.
Mounting of seals must be carried out in clean environment (no burrs, nicks and chips).
All O-rings / X-rings are replaced at service.
NOTE:
For placement and ID no., see assembly drawing.
CAUTION
At assembly of actuator on valve be aware to leave space enough for the adaptor between
actuator and valve. This means that the actuator by itself can fall down on the intermediate
flange, before tightening.
