Dish Shape Rubber Diaphragms
This form of diaphragm, generally called dish-shaped, has a sidewall that slowly slopes from the cylinder to the piston.
This dish-shaped rubber diaphragm is built to stretch to its maximum height in both directions. To absorb pressure in both directions it may be double-coated.
Complete movement and ability to withstand high pressures are limited because of its large convolution and gradual sidewall slope. The effective pressure differs by the stroke, too.
Some of the advantages of the dish-shaped rubber diaphragms are that it's pressure loadable on both sides while having same effective area on both sides. The average stroke of this dish-shaped rubber diaphragms is H max ≤ 0.24x DW
It has low hysteresis and no stick-slip effect.
The dish-shaped rubber diaphragms can be used with regulation equipment, actuators, for dosing, for control and measurement equipment and valves.
