Pressure Reducing/Sustaining 1200–10

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

Flow Limiting Valves Model 1300

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.

Pressure Sustaining Valves Model 1200

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

Pressure Reducing Valves Model 1100

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

Hydraulic Check Valves Model 1800

Sierra Model 1800 is a hydraulic check valve is a diaphragm actuated control valve that is used to prevent reverse flow in any pipe line. It functions as a two position valve, either fully open or fully closed

Pressure Relief Valves Model 1200 R

The model 1200R Pressure Relief Valve is a hydraulically operated, diaphragm actuated automatic control valve. When there is an excess pressure in the line the valve opens to flow out the excess water maintaining a constant pressure in the line and preventing the line from bursting.

Pressure Sustaining/check feature valves Model 1200-18

The model 1200-18 Pressure Sustaining Valve with Check Feature 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 over load

Pump Control Valves Model 1900

The model 1900 pump control valve is an electrically operated – hydraulically actuated control valve used to control surges caused by pump starting and stopping and provide adjustable back pressure on pump while it is running.

Surge Anticipating Valves Model 1200R11

The model 1200R11 Surge Anticipating Valve is a hydraulically operated, diaphragm actuated automatic control valve. This valve opens in response to the pressure drop that is related to the sudden stoppage of a pump thus eliminating line surges
