Float valve
Automatic Level Control, No External Power Required
The float valve uses a buoyant float to automatically open or close the valve based on liquid level, maintaining stable water level in tanks, reservoirs or water storage systems — without external power or manual intervention.
Simple, Reliable & Compact Design
With minimal moving parts, float valves offer reliable, lowmaintenance service. Their compact design makes them easy to install in various tanks and storage systems.
High Compatibility — Multiple Materials & Media Adaptation
Float valves are available in brass, stainless steel, or plastic materials, allowing adaptation to different water qualities, corrosive media or varying temperature conditions.
Overflow Prevention & Backflow Protection for Safe Operation
By automatically shutting off inflow when the liquid reaches preset level, float valves prevent overflow and backflow — ensuring safety of water storage or supply systems.
Wide Application Range: from Household to Industrial Use
Float valves are versatile — used in domestic water tanks, building supply systems, agricultural irrigation, industrial cooling towers, water treatment storage tanks, rainwater harvesting & more.

- Application Conditions
Residential/commercial building water supply storage/water tank water tower/rainwater collection system
Used for water supply/storage tanks, rooftop reservoirs, or rainwater harvesting systems — auto filling on demand, auto shutoff at set level, preventing overflow or water waste.
Municipal & Agricultural irrigation/rural water conservancy facilities
Suitable for municipal water supply, agricultural irrigation, rural water storage facilities — maintains consistent water level and supply without manual control.
Industrial water storage/cooling/circulation systems/water supply and drainage systems
Used in industrial water storage, cooling towers, circulation systems, water treatment facilities and fire water tanks — ensures stable water level and safe operation.
Sewage treatment/wastewater tank/chemical water tank
Applicable to wastewater treatment tanks, effluent storage, or chemical water storage tanks (with proper material selection) — controls liquid level, prevents overflow and backflow.
Rainwater collection/reclaimed water/environmental protection water conservancy projects
Used in rainwater harvesting systems, recycled water tanks, environmental water management projects — automatically regulates water volume and level, reduces manual operation, enhances automation.

Hydraulically flowmodulated pressure reduction system – Costa Rica
- San Jose, the capital of Costa Rica, the Greater Metropolitan Area and Limon on the Atlantic coast and other places.
Customer/Owner: Costa Rica Water Supply Company
- Working conditions/Challenges:
The main water supply pipeline system in Costa Rica has severe leakage in the water network (long pipeline network, large difference in flow between day and night)
- The type of equipment adopted:
We provided the project party with a 24 “/600 mm pilot-operated pressure reducing valve for pressure management: downstream pressure ranged from approximately 50 psi at low flow rates to approximately 60 psi at high flow rates. To reduce the risk of leakage and pipeline rupture.
Key indicators: The installation of the pressure reducing valve can significantly reduce the overflow pressure and leakage in the downstream pipeline network.
