Product Q&A

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

In HVAC or high-rise water supply, pressure instability is common. For stability, a Self-Operated Differential Pressure Control Valve or Proportional Control Valve is recommended. These valves work without external power, using a pilot guide to sense pressure changes and adjust the valve opening, preventing over-pressure and ensuring equipment safety.

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

Fire pumps can cause a surge (water hammer) during startup, risking pipe bursts. The solution is a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve. These units have adjustable opening and slow-closing speeds, dissipating kinetic energy and protecting Fire Pump Rooms from 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 uses. Zentif's Solenoid Control Valves, using a diaphragm-based structure instead of a piston, achieve lower friction and faster response. With corrosion-resistant seals, these valves ensure bubble-tight performance in sewage or industrial wastewater settings, greatly extending maintenance intervals.

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

Thermal imbalance typically arises from static hydraulic deviation. The best solution is installing a Dynamic Balancing Electric Control Valve or a Proportional Integral Electric Two-Way Valve. These valves auto-adjust flow area based on real-time load needs. Even if other branches' pressure shifts, the valve keeps a constant flow, removing hot/cold spots and boosting energy efficiency.
