SERIES 1200-10-30 is a combination pressure Sustaining, reducing and flow limiting valve
is a hydraulically operated, diaphragm actuated control valve, When installed in line, they
sustain minimum back pressure thus prioritizing pressure zone, preventing line empting,
prevents excessive flow by limiting flow to a preselected maximum rate, and reduces a
fluctuating higher upstream pressure to lower constant downstream pressure.
