General information

Description
The type AC-OP is an actuator with integrated pneumatic positioner BLRA especially constructed as a compact extension for the Research Control® valve. The positioner BLRA (Bottom Load Reverse Action) ensures a fast and precise regulation by its high positioning precision that can be kept  independent of the changing media pressures. This actuator should be used if higher shut off forces are required at same input signal of 0.2 – 1.0 bar, by influences like e.g. friction of the packing or media pressure.

Function
The BLRA positioner is based on the force compensation method. Every position of the valve equates to a definite force on the spring. In an unbalanced state, the supply air is directed behind the diaphragm, until a balanced state is reached. The positioner ensures a given allocation of valve position and instrument signal. This is obtained by constantly comparing the instrument signal 0.2 – 1.0 bar with the travel of the valve.
