Self Operated Differential Pressure Control Valve for HVAC Water Pipeline Systems

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.

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.

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.

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.

This valve is self-operated, using medium pressure changes to maintain stable system differential pressure. It adjusts the main valve via pilot control to keep pressure differences stable, reducing hydraulic fluctuations.
