Unit-Level IoT Temperature Balancing Valve
Cloud-Based Management · Unit-Level Regulation · Precise Control
Product Performance
Size Range: DN40–DN250
0.3% High-Precision Regulation
Control accuracy up to ±0.3%, ensuring precise response to control commands even at small valve openings.
Multiple Communication Options, Flexible Networking
Supports LoRa and NB-IoT wireless communication, as well as RS485 wired communication. Communication methods can be flexibly selected based on on-site project conditions.
Integrated Anti-Tamper Design, Safe and Reliable
No exposed connection bolts. Disassembly requires dedicated tools, effectively preventing improper operation or intentional damage by unauthorized personnel and ensuring long-term safe system operation.
Zero Resistance at Full Open
Featuring a full-bore flow path design, the valve introduces almost no additional flow resistance when fully open, effectively reducing system pressure loss and lowering circulation pump load.
Zero Leakage at Full Close
The sealing structure is precisely engineered and rigorously tested to ensure reliable sealing in the fully closed position, effectively preventing internal leakage and safeguarding system operation.
Protection Rating: IP68
The entire valve meets IP68 protection standards, offering excellent waterproof and dustproof performance, significantly enhancing equipment reliability and service life.
