The pressure retaining type maintains the primary side pressure constant.
The valve opens when the primary side pressure exceeds the set value and closes when the pressure falls below the set value.
It works using the fl uid pressure only, without using any auxiliary power.
Against the fl uid power pressing up the diaphragm, the valve uses the force of
compression spring to press down the diaphragm so as to keep balance.
