GF has launched the Multi Control Valve, an integrated polymer flow control device designed to complete its LiquidCore portfolio for direct liquid cooling applications in high-density data centres. The new solution is engineered for single-phase direct-to-chip (D2C) liquid cooling systems in rack architectures exceeding 100 kW.
The Multi Control Valve combines several instrumentation and flow control functions in a single unit. Its integrated components include a valve with linear flow characteristics, an electronic actuator with a five-second fail-safe response, and five embedded sensors as standard. These comprise one volumetric flow sensor, two pressure sensors and two temperature sensors, enabling continuous monitoring of operating conditions within the cooling circuit.
The device uses ultrasonic flow measurement and monolithic ceramic pressure sensors to calculate differential pressure, temperature variance and total thermal energy distribution in real time. This consolidated approach provides data centre operators with greater visibility into cooling performance while enabling rapid adjustment of liquid flow to changing thermal and hydronic loads.
Manufactured using Polyphenylene Sulfide (PPS) and other high-performance engineered polymers, the valve body is up to 70% lighter and 50% more compact than conventional metal assemblies, according to GF. The polymer construction also avoids scaling, fluid contamination and the structural weight associated with stainless steel alternatives. Its reduced mass helps lower mechanical loads on rack manifolds and distribution piping, while its compact design supports integration in space-constrained cooling infrastructure.
The Multi Control Valve features an IP68-rated housing, a single-cable layout and process connection options including PP-H spigots and stainless steel tri-clamps. Standard communication interfaces include IO-Link, Modbus RTU and BACnet MS/TP, allowing the device to connect with different control and monitoring systems.
Charles Freda, Global Head of Data Centers at GF, said: “With the launch of the Multi Control Valve, we are providing the means to connect individual rack precision to macro-level infrastructure efficiency. By enabling rapid, intelligent flow circuit modulation to instantly match thermal and hydronic load conditions, we empower data center operators to slash parasitic mechanical losses, maintain perfect chip-level thermal stability, and actively optimize their operational efficiency.”
The launch completes GF’s LiquidCore single-source offering for direct liquid cooling. The portfolio brings together PROGEF PP-H distribution piping, custom-engineered in-rack manifolds made from SYGEF PVDF, and the Quick Connect Valve 700 for rack integration, alongside the new Multi Control Valve.
With the addition of this integrated flow control and monitoring device, GF extends its LiquidCore portfolio to address cooling requirements in high-density data centre environments, where managing thermal loads and maintaining efficient liquid distribution are central to system performance.
