Automatic Differential Pressure Control Valve for Heating Cooling System Applications

In HVAC or high-rise networks, pressure instability is common. Use a Self-Operated Differential Pressure Control Valve or Proportional Control Valve for downstream stability. These valves function without external power, adjusting via a pilot guide, preventing over-pressure and safeguarding terminal equipment.

Fire pumps create surges causing pipe bursts. Install a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve to dissipate energy, protecting Fire Pump Rooms from hydraulic shock.

Traditional solenoid valves often face coil burnout or seal wear in high-frequency operations. Zentif's Solenoid Control Valves feature a diaphragm-based structure, reducing friction and enhancing response time. With corrosion-resistant seals, these valves deliver bubble-tight performance, even in sewage or industrial wastewater, significantly extending maintenance intervals.

Thermal imbalance is usually caused by 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 demands. They maintain constant flow despite pressure changes in other branches, eliminating hot/cold spots and maximizing energy efficiency.

The differential pressure valve self-operates using medium pressure changes to stabilize system differential pressure. It adjusts the main valve via the pilot system to maintain pressure within range and reduce hydraulic fluctuations.
