Key Features

n

n
• Flow Rate: Rated at 2 m³/h, according to Runxin’s official spec sheet, which makes it suitable for smaller-to-medium filter systems.

n

• Ports: Uses ¾″ female connections for both the inlet and the drain.

n

• Operating Conditions: Handles water pressure from 0.15–0.6 MPa and temperatures between 5°C and 50°C.

n

• Power Supply: Works with a 12 V DC / 1.5 A transformer, making it energy efficient and compatible with standard control heads.

n

• Turbidity Handling: Accepts water turbidity of less than 20 FTU, which is ideal for typical filtration use.

n

• Mounting: Designed for a 2.5″-8 NPSM base and includes a 1.05″ OD riser pipe, enabling simple installation on compatible filter tanks.

n

• Sealing: Uses hermetic ceramic head faces that resist corrosion and ensure a tight, reliable seal.

n

• LED Display: The dynamic LED screen indicates when the valve is in “Service” or “Rinse,” which helps you monitor its status easily.

n

• Memory Function: After a power outage (over 3 days), the controller retains its cycle settings, and it simply flashes “12:12” when power returns to prompt a clock reset.

n

• Control Features: It includes a timer for backwash frequency, button lock (to prevent accidental changes), interlock (if used in multi-valve systems), signal output, and a pressure-relief connector.
