On June 10, 2026, the 6th Shenzhen International Data Center Liquid Cooling Technology Exhibition (CIME 2026) officially opened at the 

Shenzhen World Exhibition & Convention Center. Focusing on the current challenges of high heat density cooling in data centers, the 

exhibition showcased cutting-edge innovations across the entire liquid cooling technology supply chain, establishing a core platform for 

precise industry collaboration and technical exchange.

TONHEFLOW Electric Valves: Designed for Liquid Cooling Applications

TONHEFLOW presented its A20-M and A150-M series proportional control valves, both supporting multiple mainstream signal inputs inc-

luding 4-20mA, 1-5V, 2-10V, 0-5V, 0-10V, and RS485, enabling linear analog control. Both models have passed CE certification and feature

an IP67 protection rating, ensuring reliable compliance and quality. The A20-M series delivers a torque of 3 N.m, while the A150 series rea-

ches up to 15 N.m—offering diverse torque specifications to meet various installation and operational requirements in data center liquid 

cooling systems. 

Exhibition Highlights 

At the exhibition, the TONHEFLOW technical team demonstrated through dynamic presentations how control valves respond in terms of 

opening under various input signals. Several professional visitors showed interest in the A20-M series proportional control valves and 

engaged in in-depth discussions regarding specific installation methods and control signal compatibility.
