Diaphragm Operated

FEATURES BENEFITS Quick response High relief flow Balanced valve design Control pressures to 200 psig Non air consuming in steady state Threaded relief port Increased Productivity Reduces Energy Costs Reduced Cycle times FUNCTIONAL DESCRIPTION With pressure supplied to the volume booster supply port and no pilot signal, valve (B) is closed. Pressurizing the pilot port applies a load to dia- phragm (A). This load causes diaphragm (A). valve stem (C), and valve (B) to move downward allowing flow across the seat area between valve (B) and the body. Pressure in the output line is sensed below diaphragm...
