42-20 - DP regulator (fixed set-point)
The Type 42-20 (and 42-25) self-operated differential pressure regulators are designed to work in large heating systems and general 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 42-20 is a differential pressure regulator for installation in a bypass pipe or short-circuit pipe with a fixed set point determined by the springs in the actuator.
