【Case share】Runxin Pool Filter Valve – Suitable for hotel landscape fish ponds.
A hotel in Shanghai features an ornamental fish pond (🐠) where are bred; this system requires filtration of the fish's metabolic waste and suspended impurities. Through a continuous, stable water circulation system ♻, the water temperature, dissolved oxygen levels, and microbial balance are precisely regulated. Thirty-six Runxin top-mounted flange-connected pool filtration valves (F139B-3) have been installed, utilizing an automatic control system 💠.
Special ceramic end-face sealing structure ✨ – resistant to wear caused by particulate impurities; suitable for operation under pressure ✅; enables automatic flushing and remote control 💡 – meets water quality management requirements; ensures stable operation and hassle-free maintenance.
The Runxin Pool Filter Valve (Patent No.: ZL202120625248.2) features a specialized ceramic end-face sealing structure ✨. The stationary disc is made of a special ceramic material with high hardness and high flatness, while the moving disc is constructed from high-strength synthetic material. The interlocking and rotation of the moving and stationary discs enable seamless station switching, ensuring reliable sealing and resistance to wear caused by impurities; it can be operated directly under pressure ✅ without the need to shut off the water inlet.
The automatic system features a pressure sensor that triggers the flushing cycle based on time or the pressure difference between the inlet and outlet ports 💦; it includes an RS-485 port for connecting to PLCs or other devices to enable remote control 💡; it also comes with a power-on/power-off anti-drainage solenoid valve port – a normally closed solenoid valve can be installed here to prevent pool water from draining during backwash or forward wash cycles in the event of a power failure or interruption.
