Samson 3767

Product Dimensions：

The positioners ensure a fixed assignment between the valve stem

position (controlled variable x) and the pneumatic or electric input signal (reference variable w). They compare the input signal

received from the control unit with the travel of the control valve

and, issue the corresponding output signal pressure pst (output

variable y). A reversing amplifier for double-acting actuators

produces two opposed signal pressures.

Special features

• Arbitrary mounting position; suitable for normal or

split-range operation; excellent dynamic response; negligibly

small influence of supply air; adjustable proportional band

(P-band); adjustable air output capacity; low air supply consumption; very insensitive to mechanical vibrations; lowmaintenance compact design

• Versions for hazardous areas in type of protection "Intrinsic

Safety" II 2 G EEx ia IIC T6 or II 3 G EEx nA II T6 for

Zone 2 (see "Summary of approvals")

• Type of protection "Flameproof Enclosure" EEx d with

Type 3766 Positioner and Type 6116 i/p Converter (Fig. 2)

• Attachment to actuators according to IEC 60534-6 (Fig. 3)

• Attachment to rotary actuators acc. to VDI/VDE 3845 (Fig. 5)

Benefits of integral positioner attachment (Fig. 4)

• Tight and exact mechanical connection between actuator and

positioner. No misalignment during shipping

• Concealed linkage protected against touch and external influences to fulfill requirements of accident prevention regulations UVV (VBG 5)

• Simple pneumatic connection between actuator and positioner

• Presetting of the unit: Actuator with positioner

Optional pressure gauge for monitoring the input and output

signal pressure (dial range from 0 to 6 bar and 0 to 90 psi).

Refer to Information Sheet T 8350 EN for details on the selection

and application of positioners, converters, limit switches and solenoid valves.
