42-24/42-28 - Differential pressure regulator

The Type 42-24 (and 42-28) self-operated differential pressure regulators are designed to work in district heating systems, extended heating 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 42-24 is a differential pressure regulator for installation either in an inlet flow pipe or outlet flow pipe with set point adjustable in wide range.

The Type 42-28 is a differential pressure regulator for installation either in an inlet flow pipe or outlet flow pipe with a fixed set point determined by the springs in the actuator.
