摘要：
A method of manufacturing a valve for a fluid system is described herein. The method comprises determining a target cracking pressure for the valve of the fluid system, providing an inner wall having a first height and an outer wall having a second height, the first height varying from the second height by a height differential, and attaching a flexible membrane to the outer wall at the second height, wherein a central zone of the flexible membrane is in contact with the inner wall at the first height and the inner wall biases the flexible membrane from a neutral condition. The height differential is selected to provide resistance to displacement from the inner wall until pressure acting on the membrane exceeds the target cracking pressure.
