The Y-type basic valve of Aone-Best is the basic mother valve of all hydraulic control valves. It can equiped
with different pilot to adapt to different occasions from the function. For example, with a pressure reducing pilot,
the whole valve is a pressure reducing valve; with a pressure relief pilot, the whole valve becomes a pressure
relief valve, and so on. Valves are available in a variety of size and flange standards for selection, widely used
in municipal water supply, building water supply, air conditioning, fire protection, industrial water, power and
irrigation facilities.
