Y44H bellow pressure reducing valve Feature

Y44H bellow pressure reducing valve belongs to direct acting bellows spring pressure reducing valve.Y44H bellow pressure reducing valve is mainly consists of bellows, regulating springs, seats, disc and other parts, which use bellows to sense valve pressure to drive the disc, change and regulate valve opening to achieve the pressure-reducing and pressure-stabilizing function.Adjusting bolt of Y44H bellow pressure reducing valve is used to set outlet pressure .Y44H direct acting bellow pressure reducing valve pressure regulation and pressure stabilization is sensitive, this bellow pressure reducing valve is suitable for gas and liquid medium pipeline.
