The drain valve type affects how easily and hygienically the pouch can be emptied. The "Push-Pull" E-Z Drain Valve, featured in both Marlen 72541 and Marlen 72522, is permanently sealed to the pouch, making emptying quick and avoiding wet fingers. This type of valve offers convenience and hygiene, and is a standard feature in this product category.
