Product Q&A
Q:How to select the ideal control valve for fluctuating pressure systems?
A:
In HVAC or high-rise water systems, pressure instability is common. For stable downstream pressure, a Self-Operated Differential Pressure Control Valve or Proportional Control Valve is advised. These work without external power, using a pilot guide to adjust the main valve, preventing over-pressure and ensuring terminal equipment safety.
Q:What's the best way to prevent water hammer in fire protection systems?
A:
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?
A:
Traditional solenoid valves often suffer coil burnout or seal wear in high-frequency use. Zentif's Solenoid Control Valves utilize a diaphragm structure to minimize friction and enhance response time. With corrosion-resistant seals, they deliver bubble-tight performance in sewage or industrial wastewater, significantly extending maintenance intervals.
Q:How to address thermal imbalance in HVAC chilled water systems?
A:
Thermal imbalance stems from static hydraulic deviation. The optimal 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 requirements, 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?
A:
We offer customized material options including Ductile Iron, Cast Steel, and Stainless Steel to meet project-specific requirements.
