Overview
A diaphragm logic pressure selector selects the highest/lowest branch pressure input from zone thermostats to operate final control elements in pneumatic control applications. Replacements available for Johnson, Powers, Robertshaw, and Barber-Colman.
Features
Seven input manifold containing logic diaphragm, air filter, and restrictions.Ten sharp barb connectors for all piping requirements.Large integral filter assures clean air to the manifold.Requires no field adjustment, and plastic construction results in minimum maintenance.Two analyzers can be connected together to increase inputs to twelve.
