2800 Series PTFE Seal Pneumatic Diaphragm Control Valve with 3A Standard
1. Product Description
The diaphragm control valve is combined with the intelligent positioner (1600) and the diaphragm valve(2800). The product is easy to operate and has rich software functions. It can easily be operated via the LCD and 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.
