Product overview

ARKA A20 2 Inch Kinetic Air / Vacuum Valve is offered for application-based water-system selection in Sabah. The float-operated air/vacuum mechanism manages air intake and discharge during filling, draining and changes in water-line pressure. Select the exact valve function and installation position. Its duty is air and vacuum management in water pipelines, rather than removal of suspended solids. SWFI can review the stated model and site requirements for quotation; the final supplied configuration is subject to confirmation.
