Standard operation is normally closed (air x spring) and opened with air pressure controlled by a remote 3-way solenoid valve. When air pressure is relieved, a non-wetted internal spring automatically closes valve. 40 PSI is required to fully open the air x spring version; maximum air pressure is 80 PSI.

  • Choice of double-acting air x air or normally-closed operation
  • Bubble-tight seal with up to 25” of water
  • Minimum 40 psi opens spring-loaded version full stroke
  • Large flow area for ultra-fast drain •Accessible maintenance, even when welded into sink
  • Normally-closed design uses non-wetted, stainless steel spring
