产品优势

HTRV27M-01A 型，常态下从① 流向② 封闭，直到① 处受到足够的液压力使先导阀开启，再推动主阀芯移动，使油液从① 流向② ，当③ 口有油压，将使设定压力上升。

HTRV27M-01A is Normally, the flow direction from ① to ② is closed until enough hydraulic pressure is received at ① to open the pilot valve, and then the main valve core is pushed to move to make the oil flow from ① to ②. When there is oil pressure at ③,the set pressure will rise.
