About Solenoid Valves
A solenoid valve is a device that turns an electrical signal sent to a coil
into a mechanical movement inside the valve, thus allowing it to control the
flow of liquids or gases.
Principal of operation
M&M solenoid valves are generally to the designs shown below. Fig.1 shows
a pilot operated solenoid valve and Fig.2 shows a direct acting solenoid valve.
The coil is directly assembled on an armature tube with an armature or moving
core inside. This is assembled hermetically on to the valve body. The moving
core is held in the correct position by a counter spring. When the coil is
energised, the armature is attracted by its magnetic field and the main seal
either opens or closes leaving a passage through the valve orifice.
