Abstract
A surge reliever relief valve is provided in which a flexible membrane is maintained in a peripherally sealed relationship across a rigid grid. The grid bounds the laterally adjacent intake and output regions of the valve. Intake pressure extends the membrane allowing flow between intake and output. Extension of the membrane is limited by a retainer. Extension may be elastic or inelastic.
