Two-way Valves Mounting
For NORMALLY CLOSED operation:
The ball of the valve must be rotated so that the ball is
L
ED to flow. The actuator
should be mounted with the clamp fully rotated
W (R).
pring return actuators will
show the
W (R) symbol near the clamp and position indicator. Depressing the gear
release to move the clamp rotates non-spring return actuators
For NORMALLY OPEN o
eration:
The ball of the valve must be rotated so that the ball is
PEN to flow. The actuator should
be mounted with the clamp fully rotated
W (L).
pring return actuators will show the
W (L) symbol near the clamp and position indicator. Depressing the gear release to
move the clamp rotates non-spring return actuators. There are marks on the top o
the
valve stem, which indicate the
ort directions
