Better height-to-diameter ratio, therefore longer travel
More efficient seal
Greater resistance to pressure
Possibility of using all types of rubber and fabric inserts
Lower sensitivity and greater hysteresis
The ply is not positioned at centre, as with the rubber-coated fabric, but on the outside surface. As a result, the differential pressure will always be applied to the side of the rubber.
Disadvantages: Lower sensitivity and greater hysteresis; The ply is not positioned at centre, as with the rubber-coated fabric, but on the outside surface. As a result, the differential pressure will always be applied to the side of the rubber.
Diaphragms, in different materials and with different designs, are employed in the following machineries:
Pressure regulators
Flow regulators
Linear actuators
Pneumatic servo-mechanisms
Positioning valves
Safety valves
Acceleration pumps in carburetors
Pressure stabilizers
Pressure transducers
Brakes
Pneumatic switches
Household hot water regulators
Dosing pumps
Waste-gate valves in turbo-compressors
