The ST series foot valve is a pneumatic control component mainly used to control the movement of actuators such as cylinders by reversing the air path through foot operation. Its core functional features are as follows:

Features

Control method

Using foot pedal operation, the valve core is driven to move by stepping on it, achieving the on/off or reversing of the air path. After release, it usually automatically resets by relying on a spring

Some models (such as ST-402F) support the cylinder to pause at any position and achieve precise positioning by controlling the opening and closing of the air circuit

Valve body structure

Adopting an integral slot slide valve structure, it is easy to operate and responsive.

High precision finishing technology is used to process valve holes, extending their service life.

The valve body is first oxidized and then painted to adapt to harsh working environments.

Model and compatibility

Common models include ST-402, ST-403, ST-402A, ST-403A, etc. Some models can replace FV320/FV420 series foot valves

Support multiple specifications of tracheal connectors (such as 4mm-12mm) to meet different gas path requirements

Application scenarios

Widely used in scenarios that require manual operation such as mechanical processing and automation equipment, the cylinder can be extended or stopped by stepping on it to improve operational efficiency

Installation precautions

Before installation, it is necessary to check whether the components are damaged and ensure that the gas flow direction and connection are correct.

Some models (such as the 4F210-08L with self-locking function) need to be configured according to actual needs
