Mechanical connection for pillar version - Fig. 3
Connection procedure:
• The valve (B) is put to the position „closed“ and the
actuator (A) to a mid-position.
• Loosen the nuts (4) on the pillars (6).
• Screw the pillars (6) with the cross system into the valve
flange (13).
• Tighten the pillars (6) nuts.
• Unscrew the coupling (3) screws (7) to dismantle the
coupling into parts.
• Screw the coupling (3) nut onto the valve shaft (10) to
reach the connecting size H in accordance with the table
and the actuator nameplate.
• Unscrew the coupling (3) nut by one revolution and lock it
by a nut (12).
• Use the hand wheel (2) to put the actuator output shaft
next to the valve (10), and screw the coupling parts
together.

Mechanical connection for versions with flange (Fig. 4)
Connection procedure:
• Set the actuator (A) and the valve (B) to the position
„closed“.
• Place the actuator (A) onto the valve (B).
• Tighten the central nut (11) to connect flanges (13) and
(5).
• Unscrew the coupling (3) screws to dismantle the coupling
into parts.
• Screw the coupling (3) nut onto the valve shaft (10) to
reach the connecting size H in accordance with the table
and the actuator nameplate.
• Unscrew the coupling (3) nut by one revolution and lock it
by a nut (12) to create the prestress onto the valve seat.
• Use the hand wheel (2) to put the actuator output shaft
near the valve (10), and screw the coupling parts together.
