Booster Pump E3113-06 / E4113-06
The E3113-06/E4113-06 valve is a globe pattern hydraulically operated automatic control valve, active check valve, that isolates the pump from the system during pump starting and stopping to prevent and avoid surges and water hammer events.
The valve opens and closes in response to signals applied to the solenoid on the circuit where a needle valve will adjust the response time for an accurate and smooth regulation.
Equipped with a limit switch activated by the position indicator’s movement, made in ductile cast iron and stainless steel, the valve is designed to reduced head loss, throttling noise and cavitation damage.
Flange drilling according to EN 1092/2, different on request.
Certification and testing according to EN 1074.

How it works
When pumps are turned off the valve (9) is closed and the solenoid (13) is de-energized.
When the pump starts, the solenoid (13) is energized and the control chamber (10) is put in communication with the downstream pressure thanks to the hydraulic accelerator (7), thus pushing the obturator (11) upwards to generate a gradual increase of the flow rate.
The needle valve (3) ensures the regulation of the opening and closing speed, to avoid sudden variations in pressure.
When shut down is required, the pump is kept running while the solenoid (13) is de-energized diverting, through the flow accelerator (7), the upstream pressure towards the control chamber (10) with gradual closing of the obturator (11) onto the seat (12).
Once the indication rod (15) has reached a pre-determined position (adjustable, usually the 20% of the valve stroke), the limit switch (6) will send a signal for the pump to close. In case of power failure, the backflow through the main valve (9) is prevented thanks to the check valve (8) allowing the downstream pressure back to the control chamber (10) minimizing surges.
Installation diagram
The picture below shows the recommended installation layout of E3113-06 (1) as an effective surge prevention system and protection device for water pumping stations, in combination with pressure relief valves model E3116-10 (2) or surge anticipating E3116-52 valve.
Anti-slam combination air valves are recommended upstream (3) and downstream of the booster pump control as well as sectioning devices and bypass required for the proper maintenance.
