Electropneumatic positioner 3730-31000000400000014 G1⁄4

Samson 3730-0 positioner, type 3730-1 with LCD, output. Kvs: 0.15; vx. Kvs: 0.09

Single-acting or double-acting positioner for mounting to pneumatic control valves

The positioner provides the specified purpose
The position of the valve (controlled variable x) on the input signal (set Point W). It compares the input signal received from the control

The system moves the control valve and outputs the appropriate pressure output signal (output variable y).
