Description
The valve is electromagnetically operated and has
a rubber diaphragm as its opening and closing
element. The valve utilises the water supply
pressure when opening and closing.
When the valve coil is de-energized, the valve is
closed. The water pressure builds up over the
diaphragm through the diaphragm pilot pressure
opening and holds the valve closed.
When the coil is energized, the plunger is pushed
up and the water pressure above the diaphragm
can be relieved through the pressure balancing
canal to the valve outlet. At that point, the water
pressure in the flow pipe can lift the diaphragm,
allowing the valve to open.
There is a close-meshed filter which filters
polutants in the inlet pipe. The filter is easily
removable for cleaning.
In the outlet, a throttle adjusts the water flow to the
machine requirements.
