Product Description

Y13H internal screw piston steam reducing valve This series of pressure reducing valve belongs to pilot piston pressure reducing valve. It is composed of two parts: main valve and pilot valve. The main valve is mainly composed of the seat, the main valve disc, the piston, the spring and other parts. The pilot valve is mainly composed of the seat, valve disc, diaphragm, spring, adjusting spring and other parts. By adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the change of outlet pressure, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttling part of the flow area, to achieve pressure reduction and pressure regulation function.
