Water Supply Pump Control Valve with Slow Closing Function

In HVAC or high-rise networks, pressure instability is common. For stability, use a Self-Operated Differential Pressure or Proportional Control Valve. They work without power, using a pilot guide to sense pressure changes, adjust valve opening, and ensure terminal safety.

Fire pumps can cause a massive surge (water hammer) at startup, risking pipe bursts. Use a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve. These feature adjustable opening and slow-closing speeds, dissipating kinetic energy and safeguarding Fire Pump Rooms from hydraulic shock.

Traditional solenoid valves often face coil burnout or seal wear in high-frequency use. Zentif's Solenoid Control Valves use a diaphragm-based design to reduce friction and enhance response. Corrosion-resistant seals ensure bubble-tight performance in sewage or industrial wastewater, extending maintenance intervals.

Thermal imbalance arises from static hydraulic deviation. Use a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve for optimal results. These valves adjust flow based on real-time loads, maintaining constant flow despite pressure changes, eliminating hot/cold spots, and boosting energy efficiency.

The valve uses pipeline pressure and a diaphragm to work without an electric actuator. When the pump starts, pressure opens it gradually, building pressure smoothly. On stopping, pressure changes, closing the valve in stages to limit reverse flow and reduce water hammer.
