EXP
Pneumatic Diaphragm-Balanced Liquid Dump Valves balance upstream vs downstream pressure via communication of the process fluid above and below the balancing diaphragm in order to eliminate imbalance of opening/closing forces due to pressure differential.
Designed for liquid systems, and available in either pressure-opening (normally closed) or pressure-closing (normally open) configurations.
