The Flow Stop Valve can be used in all applications where undesirable large flow rates of compressed air can cause damage to pump diaphragms. The Flow Stop Valve limits the max. flow to a set value. This prevents an overload of the pump if there is a lack of medium to be pumped. 

If the limit value is exceeded, the valve stops the flow automatically and the pump is shut off completely. The pump only can be restarted by pressing the reset-button.
