Retroﬁtting

Mounting the actuator

GESTRA continuous blowdown valves BA 46 and BA 47 can be retroﬁtted with a GESTRA actuator EF...

(BAE 46, BAE 47).

During operation moving internals can pinch one‘s hands or ﬁngers. Do not touch moving

parts! The continuous blowdown valves BAE 46, BAE 47 are remote controlled and can

open and close very abruptly.

The terminal strips of the actuator EF ... are live during operation.

This presents the danger of electric shock.

Cut off power supply before ﬁxing or removing the equipment.

Danger

1. Observe the installation instructions of the actuator manufacturer.

2. Attach compression spring 2, thrust washer 3 and grooved dowel pin 4 to actuator 1

EF... , Fig. 13

Put coupling 8 onto control lever U and ﬁx the mounting bracket 5 and actuator 1 with hexagon

screws 7 to the valve body. Align control lever until the coupling makes contact.

Align the actuator, making sure that the coupling 8 is level on the control lever. Fasten hexagon

screws 7 with a torque of 7 Nm.

Adjust the switching cams for OPEN, CLOSED and OPERATING POSITION or, if ﬁtted, the feedback

potentiometer according to the attached installation manual “Actuators EF...”.

Set the switching cam for CLOSED in the actuator such that the torque checking pin 6 is to the

right but does not touch the checking hole.The closing torque in this position is 10 Nm. Fig. 13

7. Remove

ATEX marking M from the valve body K. BAE 46, BAE 47 must not be used in potentially

explosive areas.
