Pressure-Reducing Valves
Used when a circuit branch requires lower pressure than the main system.
What is happening technically?
Two-way and three-way types behave differently. Drain and return pressures may affect the regulated pressure.
In practice
Pressure for a clamping actuator can be limited separately from the main press circuit.

Symptom → check → solution
If movement, pressure or temperature changes, first identify the conditions in which the symptom occurs. Record existing gauge readings. Base maintenance or circuit examination on causes confirmed by measurements.
