Summary
Differential pressure regulators, DN15–250 for installation in a bypass pipe or short-circuit pipe.
Differential pressure regulators, DN15–250 for installation in a bypass pipe or short-circuit pipe.
Application
Differential pressure regulator for extended piping systems and industrial applications for installation in a bypass pipe or short-circuit pipe.
- Suitable for circuit water water/glycol mixtures, steam and air as well as other liquids, gases and vapours (provided these do not affect the characteristics of the operating diaphragm).

Description
Differential pressure regulators, DN15–250 for installation in a bypass pipe or short-circuit pipe.
Features and benefits:
- Consisting of valve and opening actuator; valve opens when the differential pressure rises.
- Controls the differential pressure according to the adjusted set point (adjustment using a nut).
- Low-noise, medium-controlled proportional regulator requiring little maintenance.
- Spring-operated, single-seated valve with upstream and downstream balancing via a standard low-noise plug balanced by either bellows (DN15–250) or diaphragm (DN65–250).
- Selection of valve body materials.
- Suitable for circuit water water/glycol mixtures, steam and air as well as other liquids, gases and vapours.
- Part of the Series 42 Self-regulated regulators range.
Also as a fixed set point regulator, consult manufacturer for details.
