Pressure assisted solenoid valves usually have their coil mounted over the outlet.
Check that the solenoid valve flow direction in in line with the system flow requirements, typically solenoid valve is marked inlet and outlet, flow arrow or port 1 (IN) and port 2 (OUT).
Solenoid valve installed wrong way around
Check solenoid valve specification is suitable for the application.
Isolate electrical supply drain system and replace damaged components.
#SAGA ELECTRIC SOLENOID VALVE MODEL A2A INSTALL#
If the armature assembly has lime scale build-up due to hard water it is advised to install a water softener into the system to prevent lime scale in all systems.
Install a filter, such as our RPE filter assembly to remove debris in media and/or try to mount solenoid valve with armature vertical so any small particle debris will tend to gravitate down and flush out.
Carefully remove armature assembly, this will have small internal parts.
Drain the system and carefully remove solenoid valve diaphragm, avoid loosing small parts or internal springs and install new seal correctly.ĭirt Ingress in solenoid valve armature tube.
Check solenoid valve is in accordance with system requirements.
Install a well ventilated guard to protect the solenoid valve.
Carefully remove armature assembly, which will have small internal parts and replace.
Install bi-directional solenoid valve, coaxial valve or angle seat piston valve that are designed to control flow in both directions.
Check pressure control valves in system are correctly set up.
Install non return valve downstream of solenoid valve to prevent back flow.
Outlet pressure sometimes higher than inlet pressure
Install correct solenoid valve to meet the system pressure requirements.
Reduce inlet pressure or install pressure reducing valve.
Pressure difference inlet/outlet too high
Check other valves downstream in the system are not generating excess back pressure.
Check inlet and outlet pressure differential and flow are correct for the solenoid valve being used.
#SAGA ELECTRIC SOLENOID VALVE MODEL A2A MANUAL#
Check the position of the manual over ride and adjust accordingly.
Inspect the seat in the valve's body and the underside of the diaphragm or seal - clean as required.
Drain system and carefully remove solenoid valve diaphragm avoid loosing small parts or internal springs, remember seal position or take a photo so new seal is installed correctly.
Remove electrical DIN connector from coil to isolate coil.
coil will burn out quickly) to feel if there is residual magnetic field.
Lift the solenoid coil slightly (do not remove completely as an a.c.
