Data center

Fluid control valves are critical components of data center cooling systems, primarily deployed in chiller rooms, precision air conditioners, server liquid‑cooling loops, and fire‑water systems. They perform functions such as media on/off switching, flow regulation, hydraulic balancing, pressure protection, and emergency shut‑off, ensuring stable server heat dissipation and preventing equipment downtime due to cooling failures. These valves are subject to stringent requirements for sealing reliability, low flow resistance, leak prevention, and long‑term continuous operation. The working media typically include chilled water, ethylene glycol‑based coolants, and deionized water, with fire‑fighting fluids used in certain applications.

On the chilled‑water plant side, butterfly valves and ball valves are installed at the inlet and outlet of chillers, cooling towers, and circulating water pumps to enable equipment isolation during maintenance, allowing individual units to be serviced online without disrupting the overall operation of the plant. Check valves prevent backflow when pumps are shut down, thereby mitigating water hammer impacts on the piping system; safety valves and expansion tanks, together with their associated valve control systems, regulate pressure and protect the piping from over‑pressure damage. Static and dynamic balancing valves are fitted to the manifold and distribution headers to equalize flow across all cooling branches, address hydraulic imbalances in the network, and ensure uniform heat dissipation for each rack.

Precision air conditioners and liquid‑cooled cabinets are at the heart of valve applications. In air‑cooled precision air conditioning systems, electric two‑way valves regulate chilled water flow in response to temperature control signals. In liquid‑cooled server loops, small stainless‑steel ball valves and electric control valves manage high‑purity coolant, while dynamic balancing valves compensate for pressure fluctuations in the piping network, ensuring stable cooling flow to each cabinet. Emergency shut‑off valves promptly isolate the circuit upon a leak alarm, minimizing the risk of server damage caused by water ingress.

In fire protection systems, signal butterfly valves, solenoid valves, and deluge valves are used in fire‑water and heptafluoropropane piping to enable interlocked shutdown and media release in the event of a fire, thereby ensuring the fire safety of server rooms. Most of these valves can be integrated with the building’s Building Automation (BA) system to provide real-time feedback on their open/close status, enabling remote monitoring and control.

Data center valves are commonly made from ductile cast iron and 304/316 stainless steel, with EPDM seals that offer excellent aging resistance and low leakage. As liquid‑cooling technology becomes increasingly widespread, demand for compact, high‑purity, liquid‑cooling‑specific valves continues to grow. High‑quality fluid‑control valves reduce pipeline friction and lower pump energy consumption, making them indispensable components for the safe and energy‑efficient operation of data centers.

Fluid control valves are the core actuating components of water purification systems, widely used in residential water filtration, commercial direct‑drinking water applications, industrial reverse osmosis pure‑water production, and various water‑treatment equipment. They perform functions such as media on/off switching, flow regulation, pressure control, backflow prevention, and automatic flushing, directly ensuring effluent water quality, equipment safety, and the overall service life of the system. The working media in these systems typically include tap water, purified water, concentrate, and cleaning agents, which impose stringent requirements on the valves: food‑grade materials, zero leaching, reliable sealing, resistance to water hammer, and corrosion resistance.

Fluid control valves are critical auxiliary components of air compressor units, primarily used in screw‑type and centrifugal compressors as well as in downstream treatment systems. They manage compressed air on/off switching, pressure regulation, pipeline pressure relief, oil–air separation, and backflow prevention, ensuring stable supply pressure, safe equipment start‑up and shutdown, and reduced risk of unit failures. The working media include compressed air, lubricating oil, and condensate, while operating conditions are characterized by pressure fluctuations, temperature variations, and the presence of oil and water. Consequently, these valves must provide reliable sealing, rapid response, and excellent fatigue resistance, making them well suited to the frequent start‑stop cycles typical of compressor applications.

Fluid control valves are core components of central air-conditioning HVAC water systems, widely used in chilled water, cooling water, and heating hot‑water circulation loops. They perform functions such as pipeline on/off control, flow regulation, hydraulic balancing, pressure protection, and media backflow prevention, directly influencing air-conditioning temperature‑control performance, system energy consumption, and equipment operational safety. Central air-conditioning systems typically operate with ambient‑temperature, low‑pressure water as the working medium, placing stringent demands on valve sealing reliability, low flow resistance, quiet operation, and resistance to water hammer. These valves are extensively deployed in chiller rooms, heat‑exchanger stations, floor‑level piping, and indoor terminal units.
