Product Q&A
Q:How to select the ideal valve for systems with fluctuating pressure?
A:
In HVAC or high-rise networks, pressure instability is common. For stability, consider a Self-Operated Differential Pressure or Proportional Control Valve. They function without power, using a pilot guide to sense pressure changes and adjust valve opening, preventing over-pressure and ensuring terminal safety.
Q:What is the best way to prevent water hammer in fire systems?
A:
Fire pumps can cause a massive surge (water hammer) at startup, risking pipe bursts. The solution is a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve. These feature adjustable opening and slow-closing speeds, dissipating kinetic energy and safeguarding Fire Pump Rooms from hydraulic shock.
Q:Are solenoid control valves durable enough for high-frequency drainage automation?
A:
Traditional solenoid valves often suffer coil burnout or seal wear with frequent use. Zentif's Solenoid Control Valves feature a diaphragm-based design, minimizing friction and boosting response. Corrosion-resistant seals guarantee bubble-tight performance in sewage or industrial wastewater, extending maintenance intervals.
Q:How to solve thermal imbalance in HVAC chilled water systems?
A:
Thermal imbalance results from static hydraulic deviation. Use 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, ensure constant flow despite pressure changes, eliminate hot/cold spots, and enhance energy efficiency.
