- Low-noise, medium-controlled proportional regulator requiring little maintenance
- Single-seated valve with a plug balanced by a stainless steel bellows or a diaphragm
- Suitable for circuit water, water/glycol mixtures, steam and air as well as other liquids, gases and vapors, provided these do not affect the characteristics of the operating diaphragm
Flow & Differential Pressure Regulators
42-25 - DP Regulator (Variable Set-Point)
Set Point Range: 0.75 to 145psi (0.05 to 10bar)
Size: 1/2" to 10"
ANSI Class: 125 to 300
Temperature Range: to 660oF ( to 350oC)
The Type 42-25 (and 42-20) 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 42-25 is a differential pressure regulator for installation in a bypass pipe or short-circuit pipe with set point adjuster via external springs set. The valve opens when the differential pressure rises.
