Product Q&A

Q:How to select control valve for fluctuating pressure?

In HVAC or high-rise systems, pressure instability is common. Self-Operated Differential Pressure or Proportional Control Valves are recommended for stable downstream pressure. They work without external power, using pilot guides to adjust the main valve, preventing over-pressure and ensuring safety.

Q:Best way to prevent water hammer in fire systems?

Fire pumps can cause 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 protect Fire Pump Rooms from hydraulic shock.

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

Traditional solenoid valves often face coil burnout or seal wear with frequent use. Zentif's Solenoid Control Valves have a diaphragm design to reduce friction and enhance 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 based on real-time needs, maintaining constant flow despite pressure changes, eliminating hot/cold spots, and enhancing energy efficiency.

Q:What materials are available for the valve body?

We offer customized material options including Ductile Iron, Cast Steel, and Stainless Steel to meet project-specific requirements in different regions.
