Upstream Pressure Support Hydrovalve with remote Electric Control - E3116-31 / E4116-31
The automatic valve supports the upstream pressure regardless of flow rate variations; the calibration value is adjustable.
With the aid of a solenoid valve, it is also possible to open or close by means of a control unit or remote impulses.
If the upstream pressure should fall below the calibration value, the valve will move to the fully closed position, ensuring operation even in static conditions.
Flange drilling according to EN 1092/2, different on request.
Certification and testing according to EN 1074.

How it works
The automatic valve is controlled by an adjustable two-way pilot (5) which receives, through the regulation unit (4), the upstream pressure value.
When the latter rises above the set-point, the pilot (5) opens; the pressure in the valve chamber (10) consequently decreases, causing the shutter (11) to rise.
When the pressure is lower than the set value, the pilot reduces the degree of opening by modulating; the pressure in the chamber (10) increases and the shutter (11) descends towards the seat (12), reducing or interrupting the flow through the main valve.
Furthermore, a solenoid (14), which acts on a two-way auxiliary valve (13), interrupts the flow of the circuit, causing the main valve to close in response to remote impulses. Upon request, it is also possible to force the total opening of the hydrovalve.
Installation diagram
In the installation diagram of the valve, connected to an electronic control unit (7) which sends pulses to the circuit solenoid, shut-off devices (1, 2) and bypass allow maintenance,
And a filter (3) holds back possible impurity. There valve Of support to action live (4), reliable even after long periods of inactivity, represents the best solution for the bypass. The insertion of anti-water hammer vents (5, 6) upstream and downstream is also recommended.
