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 a common challenge. For consistent downstream stability, a Self-Operated Differential Pressure Control Valve or a Proportional Control Valve is recommended. These valves function without external power, utilizing a pilot guide to sense pressure changes and automatically adjust the main valve opening. This prevents system over-pressure and ensures the safety of terminal equipment.
Q:What is the best way to prevent water hammer in fire protection systems?
A:
Fire pumps often generate a massive surge (water hammer) during startup, which can lead to pipe bursts. The professional solution is installing a Multi-Functional Pump Control Valve or a dedicated Water Hammer Arrestor Valve. These units feature adjustable opening and slow-closing speeds, effectively dissipating kinetic energy and protecting the infrastructure of Fire Pump Rooms from hydraulic shock.
Q:Are solenoid control valves durable enough for high-frequency drainage automation?
A:
Traditional solenoid valves often suffer from coil burnout or seal wear in high-frequency operations. Zentif's Solenoid Control Valves utilize a diaphragm-based structure rather than a piston design, resulting in lower friction and faster response. Combined with corrosion-resistant seals, these valves maintain bubble-tight performance even in sewage or industrial wastewater environments, significantly extending maintenance intervals.
Q:How to solve thermal imbalance in HVAC chilled water systems?
A:
Thermal imbalance is usually caused by static hydraulic deviation. The most effective fix is the installation of a Dynamic Balancing Electric Control Valve or a Proportional Integral Electric Two-Way Valve. These valves automatically adjust the flow area based on real-time load requirements. Even if the pressure in other branches changes, the valve maintains its own constant flow, eliminating hot/cold spots and maximizing energy efficiency.
