Electric Remote Controlled Shut-off E3113-12 / E4113-12
The automatic valve opens or closes based on the pulses sent to a solenoid included in the circuit, regardless of the upstream pressure fluctuations.
The needle valve, positioned on the chamber, will allow the regulation of the circuit flow in order to avoid sudden closures and water hammer phenomena.
Equipped with a visual position indicator and made entirely of stainless steel and ductile iron coated with epoxy paint using the FBT (fluid bed technology ) technique, the valve is designed to reduce pressure drops, vibrations and damage related to the cavitation phenomenon.
Flange drilling according to EN 1092/2, different on request.
Certification and testing according to EN 1074.

How it works
The valves are activated from a solenoid (5) connected to a control unit or remote control system.
The valve can be set as normally open or closed when the solenoid is not energized.
The accelerator of flow (4) are present in the models with diameter 150 mm or more. In case of normally open valve, when the solenoid (5) is energized, there pressure of mountain he comes addressed into the valve chamber (10), directly or through the flow accelerator (4). The shutter (11), consequently, descends onto the seat (12) causing the flow to be interrupted. When the impulses to the solenoid cease, the pressure is released from the room (10), in way from to do to go back up the shutter and open the valve.
The flow in and out of the main chamber (10) is controlled by the needle valve (2) which prevents possible water hammer during closing. A filter (3) also protects the solenoid and other components of the circuit from impurities and debris.
Installation diagram
The image shows the installation diagram of the hydraulic valve in the case of using an electronic float probe (2) to regulate the level of a tank.
The solenoid must be connected to a digital programmer or other control devices. Shut-off devices (1) and bypasses to allow maintenance and a filter (3) are recommended.
The installation of combined anti-water hammer vents upstream of the valve is also recommended.
