In district heating systems, high-performance butterfly valves are crucial for efficient thermal energy transmission and control. Their ability to withstand high temperatures, pressures, and rapid actuation makes them ideal for demanding applications.
Key Applications:
- High-Temperature Hot Water/Steam Pipelines:
Precise control of high-temperature water (up to 150°C+) or steam flow/pressure.
Stainless steel/nickel-based alloys ensure durability and prevent seal failure.
Rapid closure for emergency shutdown prevents energy loss and equipment damage.
- Heat Stations & Heat Exchanger Systems:
Accurate regulation of primary/secondary flow for optimal thermal energy distribution.
Sensor integration maintains temperature stability and reduces energy fluctuations.
- Circulation Pumps & Pressure Management:
Flow modulation prevents water hammer and protects circulation pumps.
Low-flow-resistance design minimizes energy consumption.
Dynamic pressure stabilization during system fluctuations.
- Makeup Water & Water Treatment Systems:
Precise makeup water flow control maintains system levels.
EPDM/fluororubber seals resist chemical corrosion.
PTFE-lined valves for chemical dosing lines handle acidic/alkaline media.
- Emergency Safety & Maintenance Isolation:
Segmented isolation enables repairs with minimal service disruption.
Lightweight design for easy operation.
Interlocking control systems for rapid shutdown in emergencies.
- Large-Diameter Pipeline Applications:
Cost-effective and easy to install in DN300+ pipelines.
Low-torque actuation for energy-efficient operation.
- Intelligence & Energy Efficiency Optimization:
IoTintegration for real-time monitoring and automation.
Dynamic flow regulation reduces overheating and supports carbon neutrality.
Key Advantages:
- High-Temperature/Pressure Resistance: Operate from -50°C to 600°C, pressure ≥ PN25.
- Longevity & Low Maintenance: Hybrid seals extend service life.
- Rapid Response: Achieve 1–3-second actuation (pneumatic).
Environmental Adaptability: Frost-proof design prevents freezing.
High-performance butterfly valves are essential for efficient and safe district heating operations. Smart upgrades and IoT integration align with modern trends, contributing to sustainable energy management.
