Smart Valve Technology

During some extreme conditions, the air valve of an air operated diaphragm pump can experience spool centering, causing equalization of pressure behind each diaphragm. To solve this, Yamada engineered an SVT retrofit kit designed to pneumatically activate the air valve to instantly start the pump operation, therefore ensuring continued productivity.

The Yamada DRD-100 Dry Run Detector provides protection to your air operated diaphragm pump from excessive cycling once it senses an increase in air volume, due to the loss of prime or dry running, and will automatically deactivate the pump. This will not only save air consumption but also your diaphragms.
