Hydromodul Solenoid Control Valve

WORKING CONDITIONS
The valve shall be an hydraulically operated, diaphragm actuated designed to open by electric command.
The valve shall operate by means of a solenoid, that open totally the valve when is activated.

INSTALLATION

•  Prepare the pipe leaving the right distance between the flanges or between the threaded connections.
•  Clean the pipeline to avoid the entrance of extraneous material inside the valve.
•  Install the valve putting the arrow on the body in the same direction of the water flow.
•  Don’t make welding on the pipe near the valve to avoid any diaphragm damage.
•  Connect the solenoid pilot a to an appropriate power supply.

USE INSTRUCTION

•  Check that the connections between solenoid and main valve follow the outline indicated from the constructor.
•  Open the onoff ball valves N°2 and N°8 of the hydraulic  Check the upstream pressure don’t fall down below 2 bar otherwise the valve don’t work.
•  Open the water to the pipeline. Allow the valve to open ensuring the solenoid is correctly activated (solenoid open position).
•  The hydraulic circuit is equipped with a needle valve that is factory setted and leaded. Changing this setting can cause functional problems and cause the warranty loss.
•  In phase of starter, the air presence in the chamber could inuence the correct operation of the valve. In such case to supply to the evacuation total of the air vent any trapped air in the main valve as follow:
  – close the on-off valve N°8;
  – wait for the closing of the main valve;
  – close the on-off valve N°2;
  – open the on-off valve N°8 and wait the total opening of the valve;
  – open the on-off valve N°2
