5.1 Intended area of application
ThemotorvalveType3281isdesignedtocontroltheowofliquidandgaseousmedia.Onlyclean,liquidor
gaseous media that do not attack the valve body and seal materials may be controlled.
NOTE
Damagetothevalvebodyandsealsduetounsuitablemedia.
Unsuitable media can cause damage to the valve body and seals.
▶Use only suitable media.
▶Check resistance in each individual case.
5.2 Structure and function
The valve spindle is driven by a stepper motor. The rotary rotational movement of the motor is converted into
a linear movement by means of a threaded spindle. The valve spindle is rigidly connected to the threaded
spindle. The valve spindle is connected to a control cone.

Fig. 1: Structure of the valve
Theoworswitchingofthevalveisregulatedbymeansofasteppermotoractuator,whichiscontrolledby
the integrated control electronics. No external motor control is required for step control.
5.2.1 Functions of the control electronics
• Control of the valve opening by processing the external set-point values.
• Output of the valve statuses via the LED display.
• Detection of the position after power failure.
- In the event of a power failure, the current position of the valve is retained.
english

11
Product description
Type 3281
- When the voltage is applied again, the control electronics automatically detect the current position.
• Reduction of energy consumption.
- The stepper motor is only supplied with energy when it opens or closes the valve further. Owing to the
internal holding torque, the stepper motor only moves when it is controlled. In the remaining time, only the
control electronics need a basic voltage supply in order to adjust or move the stepper motor and thus the
motor valve in the event of a change in the signal input.

Table 1: Variants
The variants with integrated positioner or process controller are available in 2 options:
• Analogue: Set-point values are transmitted analogue via the standard signals,
• Digital: Set-point values are transmitted digitally via CANopen/büS.
ThevariantscanberecognizedbytheplugcongurationorontheTypelabel:Cstandsforpositioner
and D for process controller.
Both variants have special functions that can be set using the Bürkert Communicator.
5.3.1 Positioner
The positioner converts a set-point position into a valve position. The position of the actuator is regulated
according to the set-point position. The position sensor records the current position (POS) of the electro-
motive valve. This actual position is compared by the positioner with the set-point value (CMD)speciedas
thestandardsignal.Ifthereisacontroldierence(Xd1),amotorcontrolsignalisgiventotheactuatorasthe
actuating variable. Z1 is a disturbance.

The process controller is integrated into a control loop. The set-point position of the valve is derived from the
process set-point value and the process actual value, with the control parameters (PID controller). The process
set-pointvaluecanbespeciedbyanexternalsignal.
For process control, the position control mentioned above becomes an auxiliary control loop, which creates
a cascade control. The process controller in the main control loop has a PID function. The process set-point
value(SP)isspeciedastheset-pointvalueandcomparedwiththeactualvalue(PV)ofthemeasuredvariable

6.6.1 Derating
The maximum duty cycle of the valve depends on the maximum ambient temperatures, the media temperature
and the coil current of the stepper motor.
The duty cycle does not mean the duty cycle of the device but the duty cycle of the stepper motor.
This is only switched on when the valve is to move. Frequent set-point value changes drastically
increase the duty cycle of the motor.
From the derating curve it can be read which maximum duty cycle is permissible at which maximum ambient
temperature. At lower medium temperatures, higher duty cycles can be achieved.

When mounting the valve seat, the actuator must be removed. The work steps required are
described in chapter “7.4.1”.
→Screw suitable tool insert into the assembly tool.
The suitable assembly tool (order number 625604) is not included in the valve set and must be ordered
separately.

DANGER
Dangerduetolubricant.
Lubricant may contaminate the medium. There is a risk of explosion in oxygen applications.
▶Forspecicapplications,e.g.oxygenoranalysisapplications,useapprovedlubricantsonly.
→Apply lubricant to the valve seat thread (e.g. Klüberpaste UH1 96-402 from Klüber).
→Screw the attached valve seat into the thread of the valve body manually using the assembly tool.
→Tighten the valve seat using a torque wrench. Observe the tightening torques in the following table.
Tightening torques for valve seat assembly:
Valveseatsize Tighteningtorquesforcoatedseats[Nm]
4...10 20 ±3
→Screw the actuator to the valve body. The work steps required are described in chapter “7.4.2”.
7.3 Installing valve body
→Connect valve body to pipeline.
→Devices with welded connection: Weld the valve body into the pipeline. To do this, observe chapter on
Installing devices with welded connection.

Dangerduetolubricant.
Lubricant may contaminate the medium. There is a risk of explosion in oxygen applications.
▶Forspecicapplicationsuseonlyapprovedlubricants(e.g.foroxygenapplicationsoranalysis
applications).
→Beforere-installation,greasethethreadofthebodyconnection(e.g.withKlüberpasteUH196-402from

NOTE
Damagetothevalveseatsealorseatcontour.
▶When installing the actuator, the valve must be in the open position.
→Screw actuator into the valve body. Observe the tightening torque of 45±3Nm.
7.5 Turning actuator
Thepositionoftheportscanbeseamlesslyalignedbyturningtheactuator360°.
NOTE
Damagetothevalveseatsealorseatcontour.
▶When turning the actuator, the valve must be in the open position.
→Clamp valve body in a holding device (only for valves which have not yet been installed).
→Move the actuator into the required position by turning it clockwise (seen from above).

DANGER
Riskofinjuryduetohighpressureandescapingmedium.
If the direction of rotation is incorrect, the body connection can detach.
▶Rotatetheactuatoronlyinthespecieddirectionofrotation.
