Q22 and Q23 miniature solenoid valves are common models of two position three-way solenoid valves, with the following functional characteristics:

core functionality

Two position three-way control: By driving the valve core to switch positions through electromagnetic force, the fluid passage can be opened or closed, usually used to control the reciprocating motion of pneumatic actuators (such as cylinders).

Quick response: Adopting a piston direct acting or pilot operated structure, it has a fast response speed and is suitable for automation scenarios that require high-frequency switching

Performance Characteristics

Efficient sealing and durability

Using special sealing materials and piston ring design to ensure good sealing performance even after long-term use, and not easily stuck by the medium

The metal piston does not directly rub against the valve chamber, extending its lifespan and supporting installation in any direction

Environmental adaptability

Some models have waterproof performance (such as QF1 series), suitable for open-pit working environments such as mines

Supports zero pressure start-up and can still work stably in low-pressure or small-diameter pipelines

Flexibility and Security

There are various forms of coil packaging, such as insulation paint sealing and epoxy resin packaging, to meet different voltage requirements (DC 24V-220V)

Low risk of external leakage, especially suitable for safety control of corrosive, toxic or high and low temperature media

Typical Applications

Industrial automation: used to control pneumatic or hydraulic actuators such as cylinders and analytical instruments

Precision equipment: such as the switching of compressed air pipelines in optical processing machines.
