Start & Stop Valve
These are typically two solenoid coil wounded in a bobbin at the different winding directions of one after another. It has two power sources, one is for the open coil & another one is for the close coil. If the open coil is energized, the valve gets open, and it remains open even the electrical supply is removed. This is because of the latching effect of the magnets. The valve can get closed while giving the electrical supply to the closed coil. The operating pressure may vary since these are customized ones.

Relief Valves
A 3 port valve and the inlet & outlet port vent port are introduced to release the excess pressure. The function of this valve is to limit or control the pressure until the set pressure is reached. In further, the safety valve removes the extra pressure. The operating pressure may vary since these are customized ones.
