U-ideal self-operated actuators provide control for a wide variety of pressure regulation applications. Coupled with an easy control valve, these actuators can be either self-operated (using process pressure as a signal), or remote-operated. Typical industrial applications include pressure control of water, steam, oil, gas, and other fluids.

A Gas pressure relief(K type), no need of filter.
B Gas pressure regulator(B type), no need of filter.
C Liquid pressure relief(K type), in need of filter for unclean liquid.
D Liquid pressure regulator(B type), in need of filter for unclean liquid.
E Steam pressure relief(K type), in need of condenser, and filter is recommended.
F Steam pressure regulator(B type), in need of condenser, and filter is recommended.
