PIC. 1 (above): positioning of a cylinder with master valve LRX
and slave valve LRWA4-3X-4-A-00.
PIC. 2: positioning of a cylinder with valve LRX only.
SV = setpoint value; PV = process value;
A = closed loop system for master, slave valve and external sen-
sor.
Tubes to the cylinder < 2 m with an inner Ø of 4 or 6 mm to avoid
possible pressure drops. The cylinder has to be dimensioned to
provide at least 30% more force than needed.
