Combined Check Valve

Combined Check Valves or Hydraulic actuators weight loaded HAWL valves are used at all critical areas where the pipelines must be reliable, immediate and controlled quickly for valve closing, e.g. in case of external power losing, cutting off electricity cables during The earthquake, disasters In a system, ruptured pipelines, etc.) While for the valve closing is used a potential energy of lifted weight.

Motorized Control Valve Model 2300

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 Model 2200

Dual solenoid control valve is modulating valve which either opens or closes modulates receiving and electrical signal from controller to solenoid plot control

Gate valves

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

Altitude Valve Model 1600

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

Non-Modulating Float Valve Model 1500

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.

Modulating Float Valves Model 1400-1

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.

Pressure Reducing/Sustaining/Flow limiting valves Model 1200-10-30

The model 1200-10-30 Combination pressure Sustaining and reducing and flow limiting Valve is a hydraulically operated, diaphragm actuated, control valve.

Pressure Sustaining/Flow Limiting Valves Model 1200-30

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.
