3-Way Solenoid Valves

关于

3-way solenoid valves direct flow between three ports. Unlike their 2-way counterparts, limited to simply opening or closing a flow path, 3-way solenoid valves offer an additional port to enable more complex control scenarios. These valves are crucial for complex routing applications, such as mixing, diverting, or alternating flow paths within a circuit. 3-way solenoid valves can be normally closed (NC), normally open (NO), or universal. Universal means the valve can be connected in either NC or NO to select one of two fluids or to divert flow from one port to another. Suitable applications Fluid control systems: Automated control systems often use 3-way solenoid valves to start, stop, or direct fluid flow. Cylinder control: They are used to control the operation of pneumatic or hydraulic cylinders, where the valve directs air or hydraulic fluid flow into different sides of a cylinder to extend or retract it. HVAC systems: Integral in controlling refrigerant flow in heating, ventilation, and air conditioning systems. Vacuum applications: Some 3-way solenoid valves are designed to operate under vacuum conditions, controlling the flow in vacuum systems. Medical devices: Utilized for precise control of fluids and gasses in medical equipment such as dialysis machines and ventilators. Pilot valves: They can act as pilot valves that control the operation of larger or more complex valve systems. 3-way solenoid valve selection criteria Media type and materials: Choose a valve material that is chemically compatible with the media to avoid reactions and contamination. Opt for valves that prevent media contact with the solenoid (media-separated solenoid valves) for slightly contaminated media applications. Various valve housing materials are: Brass: Cost-effective and durable for water, air, and neutral gasses. Stainless Steel: Corrosion-resistant, ideal for aggressive fluids and hygienic processes. PVC: Chemical-resistant and lightweight, suitable for corrosive substances. Th
