Discover how the Runxin F135A industrial volumetric valve works in duplex water softening systems: full overview of the features, benefits, and applications.
The Runxin F135A valve controls the regeneration cycle of a water softener based on the actual volume of water treated, rather than on a fixed time schedule. This approach allows for:
- Reduced water and salt consumption
- Improved system efficiency
- Regeneration (only when needed)
This is particularly beneficial in industrial environments in which water usage fluctuates significantly.
Why Duplex Alternating Systems Matter
The Runxin F135A is specifically designed for duplex alternating systems, which consist of two tanks operating alternately. This setup ensures:
- Continuous supply of softened water
- One tank always in service, while the other regenerates
- No downtime during regeneration cycles
Thanks to a single valve, managing tanks, installation and control is simplified, while maintaining high performance.
Key Technical Features of the Runxin F135A
The valve body is made from Noryl, a high-resistance plastic known for:
- Excellent durability
- Resistance to pressure and chemicals
- Reliable performance in demanding conditions
Advanced Ceramic Disc Technology
The valve operates through high-precision ceramic discs, which provide:
- Smooth and accurate movement
- Reduced mechanical wear
- Long service life
This technology is widely appreciated in industrial applications for its reliability and consistency.
Operation and Regeneration Process
The Runxin F135A works in programmable volumetric mode, meaning:
- Regeneration is triggered automatically based on actual consumption
- No need for fixed time-based cycles
- Optimized performance and resource usage
Additionally, it uses co-current regeneration, ensuring a consistent flow direction during the process, which enhances ion exchange efficiency.
Performance and Capacity
From a technical perspective, the valve offers:
- Master valve Kv: 9.02
- Slave valve Kv: 7.5
- Resin capacity: 130 to 450 liters
- Tank size compatibility: 16” to 24”
These specifications make it suitable for a wide range of industrial water treatment applications.
Connections and Installation
The Runxin F135A is designed for easy integration:
- Inlet/Outlet connections: 1.5” male threaded
- Tank connection: 4” 8 UN male
- Drain connection: 3/4” (rear position)
- Brine line: 1/2” (side position)
The operating pressure ranges from 2 to 6 bar, ensuring compatibility with most industrial systems.
Automation and Remote Control
A key advantage of this valve is its ability to integrate with external control systems:
- Input connector for remote control signals
- Output connector for device control
For example, it can be used to control:
- Upstream solenoid valves
- Feed pumps
This level of automation enhances system efficiency and operational control.
Included Components
The Runxin F135A comes as a complete solution, including:
- Volumetric meter
- Interconnection kit between the two tanks
- Power supply
The total weight of the valve bodies and controller is approximately 17 kg.
Benefits for Water Treatment Systems
Using an industrial volumetric valve like the Runxin F135A provides several advantages:
- Increased operational efficiency
- Lower operating costs
- Continuous water supply
- Advanced automation capabilities
- Long-term reliability
These benefits make it an ideal solution for industrial and commercial facilities, and high-demand water systems.
