Product Q&A

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

In HVAC or high-rise systems, pressure may be unstable. For stable downstream pressure, a Self-Operated Differential Pressure Control Valve or Proportional Control Valve is recommended. These need no external power, using a pilot to adjust the main valve, preventing over-pressure and ensuring terminal safety.

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

Fire pumps may cause a surge (water hammer) on startup, risking pipe bursts. Install a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve to adjust speeds, dissipating energy and protecting from hydraulic shock.

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

Frequent use can lead to coil burnout or seal wear in traditional solenoid valves. Zentif's Solenoid Control Valves feature a diaphragm structure to reduce friction and speed up response. Corrosion-resistant seals ensure bubble-tight performance in sewage or industrial wastewater, extending maintenance intervals significantly.

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

Thermal imbalance stems from static hydraulic deviation. The optimal solution is installing a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve. These valves adjust flow based on real-time load demands, maintaining constant flow despite pressure changes, eliminating hot/cold spots, and enhancing energy efficiency.
