Precision Water Flow Control for Fountain Systems – Covna Valve Solutions
In dynamic fountain engineering where aesthetics meet functionality, reliable underwater flow control is paramount. Covna Valve specializes in manufacturing IP68-certified solenoid valves engineered to excel in submerged installations, combining hydrodynamic performance with artistic water display requirements.
Why Covna Valves Dominate Fountain Applications
1. Military-Grade Waterproof Protection
Achieve uninterrupted operation with IP68-rated solenoid valves, rigorously tested for continuous submersion up to 1.5m depth for 30+ days.
Triple-sealed stem design with NBR/Silicone composite gaskets prevents micro-leakage in turbulent water environments.
2. Precision Flow Engineering
0.01-25 L/min to 50-3000 L/min flow range options for precise control of:
• Pulsating musical fountain jets
• Architectural curtain water walls
• Interactive water play systemsOptional PWM/PID control modules for synchronized water-light coordination.
3. Material Innovation for Harsh Environments
316L stainless steel core components resist chlorine/brine corrosion in recirculating water systems.
UV-stabilized polymer coils maintain -20°C to +80°C operational stability for outdoor installations.
4. Smart Integration Capabilities
IoT-ready models with MODBUS/Profinet protocols for central control system integration.
Low-power design (2W-5W) compatible with solar-powered fountain installations.
