Hydrovalve for constant level control with P sustain E3110-13 / E4110-13
The E3110-13/E4110-13 automatic valve supports the upstream pressure above a value adjustable minimum and regulates the constant level of a tank regardless of the variations in the flow rate. The needle valve, positioned on the chamber, allows the adjustment of the time of valve response, so as to avoid phenomena of water hammer in the closing phase.
Made with stainless steel and coated ductile iron with epoxy paint using FBT (fluid bed) technique technology), the valve has been designed to reduce pressure drops, vibrations and damages related to cavitation phenomenon.

Features
Applications
- In break-section tanks and in pipelines gravity when control is necessary proportional level, within the limits of pilot adjustment.
- Where it is necessary to ensure the level with continuous modulation and maintain the at the same time a minimum pressure.
Accessories
- Open-close indicator.
- Manometers.
- Self-cleaning high-capacity filter.
- Modulation systems for accurate regulation with low flow rates and high-pressure differentials.
- Manual opening limiter.
Notes for the designer
- Avoid high points in the pipes connecting the valve to the pilot in order to prevent the formation of air pockets.
- For correct operation, a minimum pressure of 1 bar is required on the level pilot; lower values could cause malfunctions.
Optional configurations
- Pressure support valve and constant level regulation with system anti-backflow.
- Pressure support valve and constant level regulation with pilot quick touch.
Operating conditions
- Fluid: treated water.
- Minimum pressure: 1 bar on the level pilot.
- Maximum pressure: 16 bar.
- Recommended operating pressure: 6 bar.
- Superior on request.
- Maximum temperature: 70 °C.
Constant level pilot adjustment
- Standard stroke 85 mm; different on request.
Operation (for DN 150-600)
The E3110-13/E4110-13 is operated by two pilots, one pilot pressure support (13) followed by a pilot of proportional level control (3).
The first one opens when the upstream pressure is greater than the value on which it is set and closes by diverting the flow of the circuit to chamber (10) of the main valve when the pressure drops below this threshold.
If the tank level drops, the level pilot proportional (3) opens, releasing the pressure of the main chamber (10) through tube 5.
This causes the shutter (11) to open with respect to at seat (12) and a flow through the valve proportional to the withdrawal.
If the tank level goes back up, the pilot (3) modulates, reducing the flow of the discharge 5 until the valve is closed, if necessary main.
The pressure at the inlet and outlet of the master bedroom (10) is controlled by the exclusive regulation unit (7), equipped with filter and three adjustable needle valves, necessary for ensure stability and make opening speeds and valve closing independent of each other.
Installation diagram
In the installation diagram of the E3110-13/E4110-13, connected to the level pilot (2) by means of a single pipe, sectioning devices (1) are recommended to allow maintenance and a filter (3), upstream, to prevent the entry of impurities into the main valve. The pilot must be placed in a position protected from turbulence caused by the flow feeding the tank. In case of static pressure higher than 6 bar, the AC anti-cavitation system and a pressure reducer are recommended.
