Airtac Solenoid Valve Optimal Selection Guide for Different Industries

Introduction

Solenoid valve selection is not a "one-size-fits-all" process. Operating conditions, control requirements, and safety standards vary significantly across different industries: automotive manufacturing requires high frequency and high flow; medical equipment needs precision and safety; food and beverage require hygiene and contamination prevention; and electronics manufacturing needs miniature and clean components. As a full-range solenoid valve supplier, Airtac develops customized selection solutions tailored to the specific pain points of various industries. This article will focus on five core industries, detailing the optimal Airtac solenoid valve selection combinations to help you accurately match industry needs.
