Product Q&A

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

In HVAC or high-rise water systems, pressure instability is common. A Self-Operated Differential Pressure Control Valve or Proportional Control Valve is recommended for stable downstream pressure. Operating without external power, they use a pilot guide to adjust the main valve, preventing over-pressure and ensuring terminal equipment safety.

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

Fire pumps can cause a surge (water hammer) on startup, risking pipe bursts. Install a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve to adjust opening and closing speeds, dissipating 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 with frequent use. Zentif's Solenoid Control Valves feature a diaphragm design, reducing friction and enhancing response. Their corrosion-resistant seals ensure bubble-tight performance in sewage or industrial wastewater, significantly extending maintenance intervals.

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

Thermal imbalance stems from static hydraulic deviation. Installing a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve is ideal. These valves adjust flow area based on real-time load needs, maintaining constant flow despite pressure changes in other branches, eliminating hot/cold spots and enhancing energy efficiency.

Q:What materials are available for the valve body?

The valve body is available in Ductile Iron, Cast Steel, or Stainless Steel to meet project-specific requirements in different regions.
