The Runxin F73A TWIN automatic control valve with a flow meter is designed for backwashing water treatment filters. It helps coordinate and control the operation of industrial and commercial water treatment equipment complexes.
Used in water softening systems. It counts the water used for regeneration.
The model is designed for use in dual tanks for uninterrupted water supply.
Description
Features of F73A TWIN:
- Allows setting regeneration flow in both upflow (from bottom to top) and downflow (from top to bottom) directions.
- Utilizes high-strength ceramics to ensure zero leakage, excellent corrosion resistance, and anti-leakage protection.
- Supports manual control.
- Features a keyboard lock function: the keypad locks automatically after one minute of inactivity; to unlock, press a specific key combination.
- Helps extend equipment service life.
- Color LCD screen displays the device’s operating status and active regeneration modes.
- Indicates power supply disconnection.
- Supports remote control (via connection to an external control unit).
