Self-Operated Pilot Control: No external power needed; uses pilot-guided diaphragm for automatic pressure regulation.
Anti-Water Hammer Design: Slow closing mechanism protects pipelines from hydraulic shock and potential bursts.
Zero Leakage Performance: Bubble-tight sealing ensures no media escape under rated pressure conditions.
100% Pressure Tested: Every valve undergoes shell and seat pressure testing per ISO 5208 standard.
Modular Maintenance Structure: Pilot tubing and diaphragm can be serviced without removing the valve from the line.
Corrosion-Resistant Materials: Constructed with ductile iron, cast steel, or stainless steel for harsh environments.
Wide Application Range: Suitable for HVAC, fire protection, municipal drainage, and high-rise water supply systems.
Customizable Options: Offers customized flange standards and material options to meet specific project requirements.

Product Q&A
Q:How to select the ideal control valve for systems with fluctuating pressure?
A:
In HVAC or high-rise systems, pressure instability is common. A Self-Operated Differential Pressure Control Valve or Proportional Control Valve is ideal. These function without external power, using a pilot guide to sense pressure changes and adjust the main valve. This prevents over-pressure and ensures equipment safety.
Q:What is the best way to prevent water hammer in fire protection systems?
A:
Fire pumps generate surges during startup, risking pipe bursts. Install a Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve for protection. These adjust opening and closing speeds to dissipate energy and safeguard Fire Pump Rooms.
Q:Are solenoid control valves durable enough for high-frequency drainage automation?
A:
Traditional solenoid valves often face coil burnout and seal wear in high-frequency use. Zentif's Solenoid Control Valves use a diaphragm structure, reducing friction and improving response. With corrosion-resistant seals, they maintain bubble-tight performance in sewage or industrial wastewater, greatly extending maintenance intervals.
Q:How to solve thermal imbalance in HVAC chilled water systems?
A:
Thermal imbalance is often due to static hydraulic deviation. The best solution is installing a Dynamic Balancing Electric Control Valve or a Proportional Integral Electric Two-Way Valve. These valves auto-adjust flow based on real-time load needs. They maintain constant flow despite pressure changes elsewhere, eliminating hot/cold spots and boosting energy efficiency.
Q:Does the valve require an external power supply to operate?
A:
No, the valve is self-operated. It uses a precision pilot-guided diaphragm system that senses downstream pressure changes to automatically adjust the main valve opening, making it ideal for remote and unmanned systems.
