Product Q&A
Q:How to select the ideal control valve for systems with fluctuating pressure?
A:
For HVAC or high-rise systems, use Self-Operated Differential Pressure Valves for automatic adjustment without power, preventing over-pressure and protecting equipment.
Q:What is the best way to prevent water hammer in fire protection systems?
A:
Use a Multi-Functional Pump Control Valve or Water Hammer Arrestor to adjust opening/closing speeds, dissipating energy and protecting infrastructure.
Q:Are solenoid control valves durable enough for high-frequency drainage automation?
A:
Traditional solenoid valves face issues in frequent use. Zentif's Solenoid Valves use a diaphragm design for reduced friction, faster response, and corrosion-resistant seals for extended maintenance.
Q:How to address thermal imbalance in HVAC chilled water systems?
A:
Thermal imbalance often stems from static hydraulic deviation. The best solution is installing a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve. These valves adjust flow area based on real-time load needs, maintaining constant flow despite pressure changes in other branches, eliminating temperature inconsistencies, and enhancing energy efficiency.
