Foam Mixing Control Valve for Reliable Fire Safety Foam Applications

In HVAC or high-rise water supply networks, pressure instability is common. For consistent downstream stability, a Self-Operated Differential Pressure Control Valve or a Proportional Control Valve is recommended. These valves function without external power, utilizing a pilot guide to sense pressure changes and automatically adjust the main valve opening. This prevents system over-pressure and ensures the safety of terminal equipment.

Fire pumps often create water hammer during startup, risking pipe bursts. The solution is installing a Multi-Functional Pump Control Valve or a Water Hammer Arrestor Valve. These units have adjustable opening and slow-closing speeds, effectively dissipating energy and protecting Fire Pump Rooms from hydraulic shock.

Traditional solenoid valves often face coil burnout or seal wear in high-frequency use. Zentif's Solenoid Control Valves use a diaphragm structure, not a piston design, lowering friction and boosting response. With corrosion-resistant seals, these valves ensure bubble-tight performance in sewage or industrial wastewater, greatly extending maintenance periods.

Thermal imbalance is usually due to static hydraulic deviation. The best remedy is a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve. These valves auto-adjust flow based on real-time load. Regardless of pressure changes in other branches, the valve keeps its flow constant, removing hot/cold spots and boosting energy efficiency.
