Water purification system
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, thereby 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 chemicals, which impose stringent requirements on the valves: food‑grade materials, zero leaching, reliable sealing, resistance to water hammer, and corrosion resistance.
In the pretreatment stage, the piping for multi-media filters and activated carbon filters is equipped with manual ball valves and diaphragm valves to enable equipment maintenance isolation and switching of backwash water paths. Check valves prevent media backflow during water or power outages, thereby avoiding secondary contamination of the filter elements. Pressure-reducing valves stabilize the influent pressure, protecting the filter elements and membrane components from hydraulic shocks. The chemical dosing lines utilize corrosion‑resistant diaphragm valves to ensure precise dosing of scale inhibitors and cleaning agents.
The reverse osmosis (RO) host unit is the core component for valve applications. The feed‑water solenoid valve automatically opens and closes to regulate the supply of raw water based on system signals; the reject‑water solenoid valve controls the discharge of concentrate, enabling timed flushing of the RO membrane and delaying scaling and fouling; high‑pressure ball valves and check valves are installed at the outlet of the high‑pressure pump, designed to withstand the high‑pressure operating conditions of reverse osmosis and prevent water‑hammer‑induced damage to the membrane housing; and the pressure‑regulating valve adjusts the concentrate flow rate, stabilizing system operating pressure and ensuring optimal product‑water efficiency.
In the terminal water supply and storage section, a ball valve at the purified‑water outlet is used to shut off the water supply during equipment maintenance; a pressure‑relief valve automatically vents excess pressure when the system overpressurizes, thereby mitigating the risk of pipeline rupture. Commercial water‑purification systems are equipped with electric valves and integrated into a PLC control system, enabling fully automated operation throughout the entire process—water production, flushing, and shutdown.
The bodies of water‑purification valves are typically made from food‑grade plastics, brass, or 304/316 stainless steel, while the seals are crafted from silicone or EPDM, ensuring compliance with potable‑water hygiene standards. As water‑purification systems undergo intelligent upgrades, demand for integrated control solenoid valves and compact electric regulating valves continues to rise; these valves are not merely pipeline on/off devices but also serve as critical foundational components for the automated control of water‑purification equipment.

Fluid control valves are core foundational components in the new‑energy industry chain, performing functions such as media on/off switching, flow regulation, pressure control, safety shut‑off, and pressure‑relief protection. They are widely used across major sectors including **lithium batteries, hydrogen energy, photovoltaics, energy storage, and wind power**. New‑energy operating conditions typically feature **severe corrosion, high purity and cleanliness, high pressure or ultra‑low temperatures, flammability and explosiveness, as well as miniaturization and intelligent integration**, demanding valve materials, sealing, fatigue resistance, and zero‑leakage performance that far exceed those of conventional industrial valves.

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.
Central air conditioning and HVAC
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.
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 some applications involving fire‑fighting fluids.
