暖通空调 Industry 阀门要求

现代暖通系统要求精确流量控制、能效、静音运行以及与楼宇管理系统的无缝集成。

Precise Temperature Control

Chilled water and hot water loops require equal-percentage flow characteristics for stable temperature control across varying loads. Characterized control valve (CCV) technology ensures linear heat transfer response throughout the full stroke range.

Energy Efficiency

Variable flow systems with pressure-independent control valves (PICV) reduce pumping energy by up to 50%. Combined temperature and flow control in a single valve body eliminates the need for separate balancing and control valves.

PICV50% Energy Saving

Smart Building Integration

BACnet MS/TP and Modbus RTU communication enable direct BMS integration. Digital actuators with built-in controllers provide decentralized room/zone control. IoT-enabled predictive maintenance reduces facility operational costs.
