打開時，關(guān)閉端口2的泄漏孔。 額外的彈簧室通風在3號罐到坦克確保閥門獨立于港口2的壓力。
z Hardened and ground internal valve components to ensure minimal wear and
extended service life
z Low pressure drop due to CFD optimized flow path
z Can also be used as a logic element or unloader valve
z Spool orifice available as an option
HYDAC直動式溢流閥，溢流閥信號輸出
閥芯型HYDAC直動式泄壓閥是彈簧加載的滑閥，因為安全原因，
液壓系統(tǒng)的壓力受到限制。 不同的壓力范圍可實現(xiàn)的系統(tǒng)調(diào)整。
z Pressure relief function with external venting of spring chamber
z Good, flat curve characteristics throughout the flow range
z External surfaces zinc-nickel plated and corrosion-proof
DB16621E是直接作用的線軸型減壓閥附加彈簧室通風。
當。。。的時候端口1的壓力超過預設值值，閥芯打開，油從中流出端口1到罐口2.當閥門
