Chinese wholesale Spring Return Pneumatic Actuator - Soleniod Valve – Hankun

Product Introduction

The solenoid valve is composed of a solenoid coil and a magnetic core, and is a valve body containing one or more holes. When the coil is energized or de-energized, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off to achieve the purpose of changing the direction of the fluid. The electromagnetic part of the solenoid valve is composed of fixed iron core, moving iron core, coil and other parts; the valve body part is composed of spool valve trim, spool valve sleeve, spring base and so on. The solenoid coil is directly installed on the valve body, and the valve body is enclosed in a sealed tube, forming a simple and compact combination.

The solenoid valve is used for on-off control of liquid and gas pipelines, and is controlled by a two-position DO. Generally it is used for the control of small pipelines and is common in pipelines of DN50 and below. The solenoid valve is driven by a coil and can only be opened or closed, and the action time is short when switching. Solenoid valves generally have a very small flow coefficient and can be reset after power failure.

The solenoid valves commonly used in our production include 2/3way, 2/4way, 2/5way, etc. According to the requirements of the environment, common solenoid valves are of ordinary type, explosion-proof safety, and intrinsically safe type.
