A 2-way solenoid valve is a compact component that controls the inward and outward flow of media through a system. It’s actuated by electrical input that energizes the solenoid coil, creating a magnetic field that moves a plunger or armature to open or close the port.

These valves act as an on/off switch and provide precision media regulation in air and inert control systems. That makes 2-way pneumatic solenoid valves suitable for compressors, actuators, gas dispensing equipment and much more.

Key Features of 2-Way Pneumatic Solenoid Valves

Normally open vs. normally closed configurations: A 2-way valve can be configured for normally closed or normally open operations, or the position of the valve at rest. A normally open valve allows media to flow through the valve body when it’s not energized, while a normally closed valve seals off the orifice until it’s actuated.

Compact: Designs are becoming smaller and lighter, making these valves effective options for systems with limited space and multiple components. They don’t require as much room in manifolds and panels, so you can fit them in to suit your specifications.

Fast response: This type of solenoid valve moves quickly upon actuation. That allows for precision control over media flow, which can make or break a system, depending on its requirements and use.

Automation compatibility: You can integrate a 2-way solenoid valve into a system with sensors, Internet of Things (IoT) and remote operation. That helps improve efficiency and accuracy by removing manual interference, which is important when working in hazardous environments.

Types of Applications

Industrial

These valves are suitable for controlling pneumatic actuators and cylinders in manufacturing and automation applications like assembly lines. You can also implement them to enhance media regulation and operational safety in chemical processing, water treatment and HVAC systems. The on/off actuation allows for fast, hands-free control for conveyor belts, air systems and pick-and-place robotics.

Process Control

Two-way pneumatic solenoid valves work as the start and stop points. They’re ideal for process control applications such as dispensing, isolation, sequencing and pressure regulation. Some 2-way pneumatic solenoid valves have fail-safe designs that enhance venting, purging and pressurizing media. You can find these valves in sealing and labelling equipment in the packing industry and in automated bottling and dispensing systems in food and beverage equipment.
