In order to control water flow and pressure we supply and install these products Control Valves
An automatic control valve comprises the following components: Basic valve
One or more pilot valves
Solenoid pilot valve (on electrically actuated valves)
Control tubes and fittings
Filter for the actuation pressure source
Additional accessories (relays valves, check valves, needle valves, etc.)
Manual On-Of Valve (M) Equipped with a 3-way manual selector valve, permitting the selection of “open” or “closed”
positions on the main valve. Control Devices: 3-way valve
Availability: All 3-way controlled valves Electric Control Valves (EL)
This 3-way solenoid valve is activated by an electric current or electric pulse, opening or closing the main valve. The “Normally
closed” position of the main valve is standard. The “Normally open” position is optional. An electric activation feature may be added to most control valves upon request.
Control Devices: Sizes 3/4” - 6” - Solenoid Valve Sizes 8” - 24” - Solenoid Valve + Accelerator Relay
Availability: All models
Pressure Reducing Valves (PR) This valve maintains a preset downstream pressure, regardless of
upstream pressure or flow rate fluctuation. The main valve is controlled by a 3-way pilot valve (permitting full opening when downstream pressure drops below the set-point) or by a 2-way pilot valve (creating a pressure
differential in any condition). Availability: All models
Pressure Sustaining /Relief Valves (PS) This valve maintains upstream (inlet) pressure, regardless of
flow rate variations. The valve will be in the “closed” position if the inlet pressure drops below the set-point. Opens fully when upstream pressure exceeds the set-point.
Availability: All models Quick Relief Safety Valves (QR) This valve opens instantly when the pressure in the pipeline exceeds the safe level, thus relieving excess pressure in the network. When pressure returns to normal, the valve closes slowly, at an adjustable pace.
Availability: All models. |
