Product Description

CHX900 Intelligent Electrical Valve Positioner

Suitable for Pneumatic Control Valve Systemsw

Product Summary

The CHX900 intelligent valve positioner is a dual line instrument based on piezoelectric valve technology. It receives 4-20mA current control signals and accurately controls valve opening through the processing of a built-in high-performance microprocessor. The device adopts fuzzy PID optimal control internally and supports 4-20mA valve opening transmission function.

Key Features

Quick and easy self-setting capability
IP66 protection level for harsh environments
Built-in filter element at air source input for clean air supply and piezoelectric valve protection
External exhaust design prevents air source from entering the body interior, protecting circuit boards from corrosion
Near-zero gas consumption in standby mode for effective energy savings
