ABSTRACT:
A pressure relief valve for use with inflatable devices such as life rafts and escape slides which provide significant improvement in exhaust flows while maintaining a highly desirable compact configuration, particularly as to the height dimension. The pressure relief valve including a poppet having a protected skirt thereon which is biased within a valve body to maintain pressure within the inflatable device unless a preselected maximum pressure is exceeded whereby the poppet releases and opens a fluid passage to exhaust ports. The protected skirt providing a more efficient and thus improved "pop action" which results in improved low pressure PRV performance.
