Χp

Maximuaximum permissible differential pressure at which the motorized bued butterfly valve will close securely

againstgainst the pressure (close off pressure)

Mechanical design

The actuaactuator is driven by a2-position(SPDT) or DC 0…100…10 V, 4…20 mA control signal

from the c the controller and generates a rotary motion which is ch is transferred to thebutterfly

valvevia via a driver.

Theseeleelectromotoric actuators require no . They have a reversible

asynchronnchronous motor which drives the main shaft via gear tgear train, which accommodates

the diagodiagonal square head of the butterfly SQL32QL321B25, the coil spring is

fitted withd with handwheel shaft, handwheel is engagedwhenhenpushed in. For others, the

worm sham shaft is fitted with a direct-acting handwheel.

The actuaactuators are 90° rotated so as to workwith Siemens mens VKF42.. butterfly valves.

During aung automatic operation, rotation isstoppedby two builo built-in end-switches.

To prevenrevent the temperature inside the housing from fallingalling below the dew point tem-

perature, ture, the actuators areequipped with a built-in heatingeating element.

Calibration

SQL361B..

In order to determine the disc position fully closed “0%” or fully open “100%”, calibra-

tion is recommended on initial commissioning of modulating type actuator.

Prerequisites

∂ Actuator is mounted on butterfly valve

∂Rotate the actuator to the half-open position using the handwheel

∂ Housing cover is removed

SQL361B25..B50

Calibration

1. Press button S3 for 5 seconds to start calibration

2. Actuator moves to «100 %» stroke position (valve

opened) automatically

3. Actuator moves to «0 %» stroke position (valve closed)

automatically

4. Measured values will be saved in microprocessor

Warning

To avoidvoid pressure shocks on the butterfly valve, the Vhe VKF42.. must be driven to

its fully oully open position either manually or via positioninioning signal prior to activat-

ing the pthe pump(s).

Warning

Before pere performing any service work on the valve or actuatoctuator:

∂SwitchSwitch off the pump and power supply

∂Close Close the main shut-off valves in the pipe work

∂ReleasRelease pressure in the pipes and allow them to cool dool down completely

If necessacessary, disconnect electrical connections from terminerminals.

The valvevalve must be re-commissioned only with thehandwhndwheel or the actuator correctly

assemblebled.

Disposal

The devicdevice is considered electrical and electronic equipmeuipment for disposal in terms of

Χp

Maximuaximum permissible differential pressure at which the motorized bued butterfly valve will close securely

againstgainst the pressure (close off pressure)

Mechanical design

The actuaactuator is driven by a2-position(SPDT) or DC 0…100…10 V, 4…20 mA control signal

from the c the controller and generates a rotary motion which is ch is transferred to thebutterfly

valvevia via a driver.

Theseeleelectromotoric actuators require no . They have a reversible

asynchronnchronous motor which drives the main shaft via gear tgear train, which accommodates

the diagodiagonal square head of the butterfly SQL32QL321B25, the coil spring is

fitted withd with handwheel shaft, handwheel is engagedwhenhenpushed in. For others, the

worm sham shaft is fitted with a direct-acting handwheel.

The actuaactuators are 90° rotated so as to workwith Siemens mens VKF42.. butterfly valves.

During aung automatic operation, rotation isstoppedby two builo built-in end-switches.

To prevenrevent the temperature inside the housing from fallingalling below the dew point tem-

perature, ture, the actuators areequipped with a built-in heatingeating element.

tion is recommended on initial commissioning of modulating type actuator.

Prerequisites

∂ Actuator is mounted on butterfly valve

∂Rotate the actuator to the half-open position using the handwheel

∂ Housing cover is removed

Calibration

1. Press button S3 for 5 seconds to start calibration

2. Actuator moves to «100 %» stroke position (valve

opened) automatically

Warning

To avoidvoid pressure shocks on the butterfly valve, the Vhe VKF42.. must be driven to

its fully oully open position either manually or via positioninioning signal prior to activat-

ing the pthe pump(s).

Warning

Before pere performing any service work on the valve or actuatoctuator:

∂SwitchSwitch off the pump and power supply

∂Close Close the main shut-off valves in the pipe work

∂ReleasRelease pressure in the pipes and allow them to cool dool down completely

If necessacessary, disconnect electrical connections from terminerminals.

The valvevalve must be re-commissioned only with thehandwhndwheel or the actuator correctly

assemblebled.

Disposal

The devicdevice is considered electrical and electronic equipmeuipment for disposal in terms of
