AUTOMATIC CONTROL VALVES

Automatic flow limiting valve with remote electric control - E3114-01 / E4114-01

Application

Product family

Pipeline protection

The E3114-01 / E4114-01 automatic valve maintains the flow rate within a set maximum limit, regardless of pressure fluctuations.

If the flow rate remains below the value required the valve remains fully open.

Thanks to a solenoid valve, the valve can also be opened and closed remotely.

The pilot is connected to a flanged orifice to be installed on the pipeline.

Equipped with a visual position indicator in the standard version, the valve is made of stainless steel and ductile iron coated with epoxy paint using a fluidized bed technique.

Features

Applications

Downstream of pumps to prevent overloads and damages related to cavitation with remote control in case of emergency.
On the supply lines of the tanks to limit the range, even in combination with an electronic floating probe.
In the distribution networks of residential neighborhoods and industrialists to limit the flow in rush hour.

Accessories

The position indicator with 4-20 mA output.
The open-close indicator.
Manometers.
Self-cleaning high capacity filter.

Notes to the designer

Modulation systems ensure accurate regulation even with low flow rates and high pressure differentials.
For best operation, it is recommended to leave a straight section of pipe 5 diameters long between the valve and the calibrated flange, and another segment, 3 diameters long, downstream of the latter (image on the next page).

Optional configurations

Flow control valve with solenoid control and anti-backflow system.
Flow regulation with solenoid control and high sensitivity pilot.

Operating conditions

Fluid: treated water.
Minimum pressure: 1,2 bar.
Maximum pressure: 16 bar.
Maximum temperature: 70 °C.

Pilot flow regulation field

The flanged orifice is sized according to the maximum design flow rate. Variations from the setting value are possible in accordance with the flow rate table supplied with the valve.

Solenoid valve data

Voltage: 24V DC, 24V/50Hz, 230V/50Hz. Other voltage on request.
Electrical consumption: inrush AC (VA) 24, hold AC (VA) 17 (8 W), DC hot/cold coil 8/9 W.

How it works

The valve is controlled by an adjustable two-way pilot (5) for flow control, which receives the pressure downstream of the flanged orifice (13) in its cap.

When the flow rate exceeds the maximum value, the pilot (5) modulates the flow passing through it by directing the upstream pressure into the valve chamber (10), so as to lower the shutter (11) towards the seat (12) to reduce the flow.

When the flow rate remains below the established limit, the pressure at the flanged orifice (13) is less than the force of the pilot spring, so that the pilot remains completely open, as does the main valve.

Furthermore, a solenoid (16), in combination with an auxiliary two-way valve (15), by regulating the flow of the circuit, closes or opens the main valve depending on the impulses received.

The flow into and out of the main chamber (10) is controlled by the exclusive regulation unit (4), necessary to ensure stability and make the opening and closing speeds of the valve independent of each other.
