DN100 Hydraulic Control Valve with Flanged Connection and Diaphragm Chamber

In HVAC or high-rise networks, pressure instability is common. For downstream stability, use a Self-Operated Differential Pressure Control Valve or Proportional Control Valve. These function without power, using a pilot to sense pressure changes and adjust the main valve, preventing over-pressure and ensuring terminal equipment safety.

Fire pumps create a surge (water hammer) during startup, risking pipe bursts. Install a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve. These have adjustable opening and slow-closing speeds to dissipate kinetic energy, protecting Fire Pump Rooms from hydraulic shock.

Traditional solenoid valves can suffer coil burnout or seal wear in high-frequency operations. Zentif's Solenoid Control Valves use a diaphragm-based structure for lower friction and faster response. With corrosion-resistant seals, they maintain bubble-tight performance in sewage or industrial wastewater, significantly extending maintenance intervals.

Thermal imbalance is due to static hydraulic deviation. Install a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve. These adjust flow based on real-time load, maintaining constant flow despite pressure changes, eliminating hot/cold spots, and maximizing energy efficiency.

It utilizes pipeline water pressure to control the diaphragm above the valve disc. When upper chamber pressure is released, inlet pressure beneath the disc raises the assembly, opening flow. Admitting water into the upper chamber pushes the diaphragm and stem down, reducing flow or closing the valve.
