45-1/45-2 - Differential pressure regulators with closing actuator - installation in the high-pressure line

The Type 45-1 (and 45-2) self-operated differential pressure regulators are designed to work in district heating systems, extended piping systems, and industrial applications. The differential pressure to be controlled is transmitted to the spring-loaded operating diaphragm in the actuator and converted into a positioning force to move the valve plug. The regulators control the differential pressure according to the adjusted set point.

The Type 45-1 is a differential pressure regulator for installation in an inlet flow pipe with a fixed set point determined by the springs in the actuator.

The Type 45-2 is a differential pressure regulator for installation in an inlet flow pipe with set point adjustable in wide range.
