Solenoid valves are electromechanically operated devices that control fluid flow (liquids, gases, or vapors) by converting electrical signals into mechanical motion. When energized, an electromagnetic coil generates a magnetic field that moves a plunger to open or close the valve orifice. This enables rapid on/off control, directional switching, or pressure regulation in automated systems. Key structural components include the coil, core tube, plunger, seals, and valve body—each engineered for specific pressure ratings, temperatures, and media compatibility.

Pneumatic throttle valve is a regulating element used to control the flow of air flow, which is widely used in industrial automation, pneumatic systems and mechanical equipment.

Air pressure regulating valve (Pressure Regulator) is a key component in pneumatic systems, mainly used to control and stabilize the air source pressure to ensure that the equipment can operate stably within the appropriate air pressure range.

Industrial systems operate under immense pressure – literally. When hydraulic presses clamp, pneumatic arms retract, or chemical lines shut down, trapped energy doesn't just vanish. Residual pressure release valves (RPRVs) are the unsung heroes preventing catastrophic failures.

4V solenoid valves (named from "4-Way Solenoid Valve") serve as the nervous system of industrial pneumatic networks by directing compressed air flow with electromechanical precision. These valves feature 2-position/3-way (3V series) or 2-position/5-way (4V series) configurations, where the valve spool shifts to connect/disconnect ports based on electromagnetic coil activation.

In the chemical industry, the production environment is complex and highly corrosive, which places extremely high demands on the performance and reliability of the equipment.
