SVT, Smart Valve Technology

Yamada® is known worldwide for being the pioneer of the most reliable air valve technology available for air operated double diaphragm pumps. Yamada pumps are applied to thousands of unique applications within numerous industries for which we have taken on the challenge to be successful with each and every one. During some extreme conditions, the air valve can experience spool centering, which causes equalization of pressure behind each diaphragm. As a solution, Yamada proudly introduces Smart Valve Technology (SVT), a retrofit kit available for any NDP-20 through 80 series Yamada pump. The SVT unit is designed to pneumatically activate the air valve, instantly starting the pump operation.

  • Retrofit-able to existing pumps in the field
  • Completely pneumatic
  • No field adjustment required
