Increased stroke,increased valve opening and hence higher flow rate.
Decreased dynamic and inrush friction; prompter; more sensitive operation.
Reduced working stress and hence longer life allowing the use of thinner diaphragms (0.45 mm versus 1.5mm for a flat one) which increases regulator sensitivity and prompt action.
Increased accuracy in maintaining the set pressure with both variable flow rates and different feed pressures.
Downstream over pressures relieved quickly.
Each system served by the air supply mains (e.g. actuators and general appliances) requires its own constant operating pressure.
It is necessary to use a regulator to regulate the pressure within a set range by means of regulating springs, with the pressure never exceeding the mains pressure.
