2800 Series Weld Connection Pneumatic Diaphragm Control Valve with CE Certificate

1. Description

The diaphragm control valve is combined with the intelligent positioner (1600) and the diaphragm valve(2800). The product can easily be operated via the keypad. It detects the external setting signal and the signal of internal displacement sensor, and adjusts valve stroke quickly and accurately by using automatic control algorithm and PWM control technology.
