Product Q&A

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

In HVAC/high-rise networks, pressure instability is common. Choose Self-Operated Differential Pressure or Proportional Control Valve. They work without power, using a pilot guide to sense pressure and adjust valve, preventing over-pressure.

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

Fire pumps cause surges at startup, risking bursts. Use a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve. They feature adjustable opening/slow-closing speeds, dissipating energy.

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

Traditional solenoid valves face coil burnout or seal wear with high-frequency use. Zentif's Solenoid Control Valves use a diaphragm-based structure for reduced friction and better response. Corrosion-resistant seals 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 stems from static hydraulic deviation. Install 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, maintaining constant flow despite pressure changes, eliminating hot/cold spots, and enhancing energy efficiency.
