Masoneilan 174 Series Spring Loaded Regulator
The Masoneilan 174 Series regulators are a spring loaded, direct operated regulator for pressure reducing or relief applications in a variety of industrial applications. The large diaphragm area provides more accurate control at low pressure settings and the lever design provides excellent shut-off tightness. These regulators are available in ½” up to 1½” (DN15 through DN40) body sizes with a maximum inlet pressure of 145 psig (10 barg). The simple construction makes it very flexible, easy to install and to maintain.
Features
1.Flow to open or close design (depending on function)
2.Internal pressure sensing
3.Resilient single seat
4.Elastomeric Diaphragm
5.Flexible body orientation to simplify installation
6.Spring Loaded, Direct-Operated Regulator for Pressure Reducing or Relief Applications
