System VRAC Basic III Automatic Multiport Valve

VRAC Basic III operates all functions of the filtration circuit with a motor. Filtration starts from a timer on the control panel or an external command. Backwashing follows logic that combines pressure and time: the frequency is set on the keypad as weekly, daily or off, and a wash also starts when filter pressure exceeds the set limit. Rinsing runs automatically after every wash.

Recirculation and closed positions are selected with a button; the closed position isolates the pump inlet from the outlets. To prevent accidental emptying of the pool, the waste position must be confirmed at the control cabinet after being selected with its button. The valve stops the pump automatically while changing position, and an optional hydraulic safety valve can be added for protection against power failures during a position change.

The body is ABS, the distributor PPO, the spring AISI-302 coated stainless steel and the screws AISI-316. The electronic module is rated IP65; it runs on 115-230 VAC (50-60 Hz), draws max. 35 W and operates at water temperatures of 5-35 °C and up to 2,000 m altitude. The pressure sensing range is 0.3-2 bar (factory setting 2 bar). Service life is 5,000 wash and rinse programmes. It can be monitored and controlled from automation systems via the MODBUS protocol.

Top, return and waste ports are female BSP; in side mounting, the filter outlet (Bottom) is a solvent-weld connection. A connection kit for side-mount filters with a 270 mm (2") connection height is included in the package.
