Features of electronic electric single-seat control valve:
The electronic electric single-seat control valve is particularly suitable for workplaces where the allowable pressure difference is small and the allowable leakage is small. It is widely used to accurately control gas, liquid, steam and other media. The valve is controlled by current signals. opening to achieve continuous adjustment of pressure, flow, liquid level, temperature and other industrial parameters
