The model 1600 Altitude Valve is a hydraulically operated, diaphragm actuated, control valve that allows flow into the elevated tank in order to maintain the level at the designated maximum. The valve modulates to maintain the tank level. As the reservoir level drops the main valve is open proportionally to increase the filling
The Model 2500 is a Low-Power Electronic Control Valve that brings pressure management and modulation to a new level of excellence, it is a battery-operated Pressure Reducing Valve that can operate with different control modes to optimize water network pressures.
The model 2400 is a pressure management valve that reduces high line pressures to lower distribution system levels, as it can switch between two pilots by means of a latching solenoid. The solenoid control feature can be activated by an electrical signal from a battery-operated controller.
Dual solenoid control valve is modulating valve which either opens or closes modulates receiving and electrical signal from controller to solenoid plot control
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.
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
The model 1400 Modulating Float Valve is a hydraulically operated, diaphragm actuated, control valve that allows flow into the tank (reservoir) in order to maintain the level at the designated maximum. The valve modulates to maintain the tank level.
The model 1400 Modulating Float Valve is a hydraulically operated, diaphragm actuated, control valve that allows flow into the tank (reservoir) in order to maintain the level at the designated maximum.
The model 2300 is a series of motorized pilots That can be used with all network control valves pressure reducing sustaing and flow limiting valves . The Motorized pilot is basically conventional hydraulic pilot that is driven by a motor remote set point adjustment .
The model 1500 ON/OFF Float Valve is a non-modulating hydraulically operated, diaphragm actuated, control valve that functions as a two position valve either open or closed. It allows filling of the reservoir to the desired maximum high level, where it closes drip tight.
The mode 1300PB Safety- ACV valve is a hydraulically operated, diaphragm actuated, control valve that saves the pipe line by shutting off the water if the line was broken
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.
Sierra is an experienced and professional manufacturer of valves. We provide probably the most comprehensive range of valves for the water, wastewater and irrigation industry in Egypt.
