Product Q&A
Q:How to select the ideal control valve for systems with fluctuating pressure?
A:
In HVAC or high-rise water supply networks, pressure instability is common. For consistent downstream stability, a Self-Operated Differential Pressure Control Valve or a Proportional Control Valve is recommended. These function without external power, using a pilot guide to sense pressure changes and auto-adjust the main valve. This prevents over-pressure and ensures terminal equipment safety.
Q:What is the best way to prevent water hammer in fire protection systems?
A:
Fire pumps often create a surge (water hammer) at startup, risking pipe bursts. Installing a Multi-Functional Pump Control Valve or a Water Hammer Arrestor Valve is a professional solution. These feature adjustable opening and slow-closing speeds, dissipating kinetic 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 face coil burnout or seal wear in high-frequency use. Zentif's Solenoid Control Valves use a diaphragm-based structure, not a piston, ensuring lower friction and quicker response. With corrosion-resistant seals, these valves retain bubble-tight performance in sewage or industrial wastewater, greatly extending maintenance intervals.
Q:How to solve thermal imbalance in HVAC chilled water systems?
A:
Thermal imbalance is usually due to static hydraulic deviation. Install a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve for the best fix. These valves auto-adjust the flow area per real-time load needs. Even with pressure shifts in other branches, the valve holds a constant flow, removing hot/cold spots and boosting energy efficiency.
