Liquid cooling valve

Liquid Cooling Valve Models: YLQ / YLP / YLD / YLH / YLA / YLPQ / YLC Liquid cooling valves are control components specifically designed for liquid cooling systems. They are primarily used to regulate the flow rate, direction, and pressure of coolants (such as water-based coolants: deionized water, ethylene glycol/propylene glycol solutions; oil-based coolants: synthetic oils (PAO/synthetic hydrocarbons), mineral oils, silicone oils; fluorinated fluids: perfluoropolyethers (PFPE), hydrofluoroethers (HFE), perfluorinated amines (PFA)). They are key components of liquid cooling thermal management systems. Their performance directly affects the cooling efficiency, operational reliability, and safety of the system. Liquid cooling valves mainly perform three core functions: First, precise flow control via electric control valves or balancing valves to avoid localized hot spots. Second, rapid on/off switching and flow direction control using ball valves, solenoid valves, etc. Third, overpressure and backflow prevention via safety valves and check valves to protect equipment safety. The types produced by Kaivex Valve Group include ball valves (for quick isolation), electric control valves (for precise flow control), solenoid valves (for fast switching), check valves (to prevent backflow), and balancing valves (for hydraulic balance). All feature quick-connect capability (supporting hot-swappable maintenance). Liquid cooling valves have a zero-tolerance requirement for external leakage, with internal leakage meeting ANSI Class VI standards. The operating temperature range is typically -40°C to 120°C, with a pressure rating of up to 1.6 MPa.

Specification：
DN15-DN100
Pressure：
PN16
Material：
CF8, CF8M

V-port liquid cooling control ball valve is a precision control regulating valve specifically designed for the liquid cooling systems of computer computing data centers. Its core feature is the deep combination of the V-port ball core structure and liquid cooling heat dissipation application scenarios. In terms of structure, the ball core of this valve matches with a flow distribution plate with a V-shaped notch. During the rotation process, a certain shearing force is formed, which can effectively cut off micro-impurities in the medium and has a self-cleaning function to prevent jamming. Its flow characteristic is approximate to equal percentage, with a large adjustable ratio and strong flow capacity. It can dynamically adjust the coolant flow according to the heat generation requirements of the equipment, and precisely control parameters such as flow, pressure, and temperature, avoiding overcooling or insufficient heat dissipation. This valve is dedicated to liquid cooling systems, mainly regulating cooling media such as water, ethylene glycol/propylene glycol mixture with a maximum concentration of no more than 60%, deionized water, and fluorinated liquids. In terms of material selection, it is compatible with coolants (such as stainless steel body paired with fluorine rubber or perfluoroelastomer seals) to prevent electrochemical corrosion or swelling of sealing components. The internal channel of the valve body is smooth and without dead corners, with high cleanliness requirements, ensuring the long-term and reliable operation of the system.Product Image:V-port Liquid-cooled Control Ball Valve
