Changing the Actuator Connection Position

For Models VY6300X0011, VY6300X0021, VY6300X0022

(DN15 to DN25 valves):

The following is the procedure for changing the position of

the actuator mounted onto the valve.

IMPORTANT:

The actuator can be horizontally rotated every

90 degrees to fit into the valve (4 mounting

positions). Make sure the positions of the

actuator and of the valve are as follows. (see Fig.

10.)

- Actuator: The indicator/manual lever points

at ‘O’ (fully open).

- Valve: The arrow on the top of the valve

stem points at ‘O’ (fully open).

The hole on the side of the valve stem faces the

direction to which the raised part of the mounting

flange points. (See the procedure 4).)

Be sure not to mix up the combination of valve,

yoke and actuator with other combinations.

1)Move the indicator/manual lever to ‘O’ with the lever

release button pushed in.

2)Move the lock lever to the right-end.

Mount the actuator onto the valve. 4 mounting positions are

available: To combine with the valve, the actuator can be

horizontally turned every 90 degrees based on the factory

preset position.

3)Make sure that the arrow on the top of the valve stem

points at ‘O’ and that the hole on the side of the stem faces

the direction to which the raised part of the mounting flange

points.

4)Make sure that the indicator/manual lever of the actuator is

positioned at ‘O’.

5)When mounting, place the actuator on the valve mounting

flange so that the 4 projecting points on the bottom of the

actuator fit into the 4 holes on the valve mounting flange.

6)After mounting the actuator onto the vavle, move the lock

lever to the left-end (marked with the marker).

stem points at ‘O’ (fully open).

The hole on the side of the valve stem faces the

direction to which the raised part of the mounting

flange points. (See the procedure 4).)

Be sure not to mix up the combination of valve,

yoke and actuator with other combinations.

1)Change the actuator mounting position only when the

actuator is in fully open position.

2)Remove the screws connecting the actuator and the yoke.

Lift the actuator and detach it from the yoke. (Make sure

that the hole on the side of the valve stem faces the

direction to which the raised part of the mounting flange

points.) <Step 1>

3)Remove the screws connecting the yoke and the valve

body. <Step 2>

4)Change the direction of the yoke to the desired direction.

The actuator and the yoke can be horizontally rotated

every 90 degrees to fit into the valve mounting position

(0/90/180/270from the factory preset position). <Step

5)A thermal insulation sheet is inserted between the yoke

and the valve. If the mounting position is changed, be sure

to reinsert the thermal insulation sheet to fit into position (1

sheet between valve body and yoke).

6)Before attaching the yoke to the valve with screws, check

that the actuator engages correctly with the stem. (Check

that the actuator position indicator is in fully open position.)
