Fast opening and closing is gained at the expense of smoothness. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These Valves have low pressure rise vs. flow and are very fast. ·主级的阻尼孔被不锈钢滤网保护。 Main stage orifice is protected b
