R1 863,00 Incl. VAT
The Runxin F71P1 is a timer-controlled automatic 2.5″ filter valve designed to manage service, backwash, and rinse cycles on water filtration systems. It is suitable for standard top-mount filter vessels and provides reliable automated operation without manual intervention.
Runxin F71P1 Automatic Filter Valve 2.5″ Base
The Runxin F71P1 is a time-clock controlled automatic filter valve designed for use on water filtration systems requiring scheduled backwash and rinse cycles. It replaces manual multiport or lever-type valves, allowing filter media to be cleaned automatically at pre-set intervals.
This valve is commonly used on sand, carbon, and other media filtration vessels where periodic backwashing is required to maintain performance. The control head is mounted directly onto a standard top-mount filter tank and manages the operating stages electronically.
The F71P1 uses a programmable controller to initiate backwash and rinse cycles based on time settings selected by the user. During normal operation, the valve remains in service mode and automatically transitions through the cleaning sequence without requiring manual adjustment.
Designed for residential and light commercial filtration systems, the Runxin F71P1 offers a compact and practical automation solution where flow requirements fall within the valve’s rated capacity.

FAQ's
1: What is the Runxin F71P1 used for?
The Runxin F71P1 is used to automatically control backwash and rinse cycles on water filtration systems such as sand or carbon filters.
2: Is the F71P1 suitable for water softeners?
No. The F71P1 is a filter valve, not a softener valve. Water softeners require regeneration-specific control valves.
3: How does the valve know when to backwash?
The valve operates on a timer-based system. Backwash and rinse cycles are triggered according to the schedule programmed into the controller.
4: What size filter tank can be used with this valve?
The valve is designed for standard top-mount filter vessels, typically used in residential filtration systems. Tank size must align with the valve’s flow rating.
5: Does the valve work without electricity?
No. The Runxin F71P1 requires an external DC power supply to operate the control head and automatic cycling.
6: Can the backwash frequency be adjusted?
Yes. The timer allows the user to set the backwash interval based on time (days or hours), depending on system requirements.
