Sierra model 1300 flow control valve is a hydraulically operated, diaphragm actuated automatic control valve, it used to limit the amount of flow to a preselected maximum rate regardless of fluctuations in upstream and downstream pressure.
The model 1100 Pressure Reducing Valve is a hydraulically operated, diaphragm actuated, control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure
The model 1100/S Pressure Reducing Valve is a hydrauli-cally operated, diaphragm actuated, control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure, Thanks to a Sole-noid Control, the Valve will also open or close in response to a signal
The model 1310 Combination Rate of Flow Control & pressure reducing Valve is a hydraulically operated, diaphragm actuated, control valve that prevents excessive flow by limiting flow to a preselected maximum rate, and reduces a fluctuating higher upstream pressure to lower constant downstream pressure.
The model 1200–10 Combination Pressure Sustaining And Reducing Valve is a Hydraulically Operated Diaphragm Actuated Automatic Control Valves When Installed in-line ,They Sustain Minimum back pressures thus prioritizing Pressure zones preventing line emptying and it prevents downstream pressure from rising above maximum pre-set
The model 1200-10-30 Combination pressure Sustaining and reducing and flow limiting Valve is a hydraulically operated, diaphragm actuated, control valve.
The model 1200 Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated automatic control valve. When installed in-line, they sustain minimum back- pressure thus prioritizing pressure zones, preventing line emptying, and pump overload
The model 1200-30 Combination pressure Sustaining and flow limiting Valve is a hydraulically operated, diaphragm actuated, control valve.When installed in line, they sustain minimum back pressure thus prioritising pressure zone, preventing line emptying, and it prevents excessive flow by limiting flow to a preselected maximum rate.
