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 .
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 3100 – 3300 – 4300 is a ductile iron full bore double – flanged metal – seated gate valve designed to comply with ISO 5996 and BS 5163 for water, wastewater, irrigation and sewage applications
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 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 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 1200-10-30 Combination pressure Sustaining and reducing and flow limiting Valve is a hydraulically operated, diaphragm actuated, control valve.
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.
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.
