Because our plastic solenoid valves are constructed specifically to cope with challenging environments, they're ideal for use in sectors such as chemical processing, bio-medical fields, waste water and pharmaceutical applications.The chemical resistant solenoid valves we provide a made to an exceptionally high standard, resulting in durable components that work well in almost any system. Chemical resistant solenoid valves are designed to work electromechanically, providing a dependable action that can be tailored to suit your specific operational needs. Offered as 2-Way and 3-Way Valves with four internal body configurations and three seat sealing methods, our iPolymer Miniature Solenoid Valves are suitable for a wide range of ultra clean to highly corrosive media applications.

However, the direct acting type has no such strict requirement.Our iPolymer Miniature Solenoid Valves offer precision performance under extreme conditions. The pilot-operated solenoid valve has a relatively high requirement to the purity of the flowing medium. The power and consumption of the directly operated solenoid valve are higher than that of the pilot-operated type. Generally, the CV value can reach 3 or above. The flow capacity of the pilot-operated solenoid valve is bigger than that of the directly operated type. However, as to the direct acting solenoid valve, the main solenoid opens directly. When the pilot-operated solenoid valve is energized, the small valve opens at the first and the main valve opens later. Instead, the directly operated solenoid valve is opened with its main valve directly. Because the small valve opens in the first and the main valve opens later when the pilot-operated solenoid valve is supplied with power. It is mostly used for the occasion of fast connection and disconnection. The starting speed of the direct acting solenoid valve is quicker than that of the directly operated type. The pilot-operated solenoid valve has a higher tolerance of liquid pressure than the direct acting solenoid valve. Tips: Differences between pilot-operated and direct acting solenoid valve (body length unit = mm, port size unit = inch) Pneumatic solenoid valve, 2-position 3-port, normally closed, single solenoid, is used to handle the flow of air with long service life and high reliability under the working voltage of 12V DC, 24V DC, 110V AC or 220V AC, and widely used in the industrial fields like chemical, petroleum, pharmaceutical, automotive, light industry, food, mineral processing, electroplating, metallurgy, textiles etc.
