Type 4708-64xx for Type 3277 Actuator
Before attaching the supply pressure regula-
tor, check whether the tongue of the gasket
(1.2) is aligned at the connection block (1)
in such a way that the actuator symbol (1.3)

ator stem retracts” matches the fail-safe ac-
tion of the actuator.

O-ring on the positioner and actuator
yoke and fasten it with hexagonal socket
screw (3).
3. Place the supply pressure regulator with
O-ring on the connection block and fas-
ten it with hexagonal socket screw (2).
