Product Q&A

Q:How to select the ideal valve for systems with fluctuating pressure?

In HVAC or high-rise networks, pressure instability is common. Opt for a Self-Operated Differential Pressure or Proportional Control Valve. These function without power, using a pilot guide to sense pressure changes and adjust valve opening, preventing over-pressure and ensuring terminal safety.

Q:What is the best way to prevent water hammer in fire systems?

Fire pumps can cause a massive surge (water hammer) at startup, risking pipe bursts. Use a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve. These have adjustable opening and slow-closing speeds, dissipating kinetic energy and protecting Fire Pump Rooms from hydraulic shock.

Q:Are solenoid control valves durable enough for high-frequency drainage automation?

Traditional solenoid valves often face coil burnout or seal wear in high-frequency use. Zentif's Solenoid Control Valves use a diaphragm-based structure, reducing friction and enhancing response. With corrosion-resistant seals, they ensure bubble-tight performance in sewage or industrial wastewater, extending maintenance intervals.

Q:How to solve thermal imbalance in HVAC chilled water systems?

Thermal imbalance is due to static hydraulic deviation. Use a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve for optimal results. These valves adjust flow based on real-time loads, ensuring constant flow despite pressure changes, eliminating hot/cold spots, and enhancing energy efficiency.
