Product Q&A
Q:How to select the ideal control valve for systems with fluctuating pressure?
A:
In HVAC or high-rise systems, pressure instability is common. Use a Self-Operated Differential Pressure or Proportional Control Valve. These require no external power and adjust automatically using a pilot guide to prevent over-pressure, safeguarding equipment.
Q:What is the best way to prevent water hammer in fire protection systems?
A:
Fire pumps cause water hammer at startup, risking pipe bursts. Install a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve, which adjusts opening/closing speeds to dissipate energy and protect infrastructure.
Q:Are solenoid control valves durable enough for high-frequency drainage automation?
A:
Traditional solenoid valves face coil burnout or seal wear in frequent use. Zentif's Solenoid Control Valves use a diaphragm design, reducing friction and speeding response. With corrosion-resistant seals, these valves ensure bubble-tight performance in sewage or industrial wastewater, greatly extending maintenance intervals.
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.
Q:What is the working principle of this differential pressure control valve?
A:
The self-operated valve uses medium pressure changes to stabilize system differential pressure, adjusting the main valve via pilot control, reducing hydraulic fluctuations without external power.
