SCEB : 大气参考, 直动式 顺序阀 带反向流单向阀
技术特性 [ + ]

透气型,直动式带逆流单向阀的顺序阀将在进口(口1)压力超过阀的设定之后向次级油路供油。此外,此类阀内部集成单向阀,可以提供从口2(顺序口)到口1(进口)逆向液流。顺序阀的设定将控制与透气口压力相关的口1压力。

  • 适合使用在负载锁紧应用中。
  • 透大气阀只用在不能连接外泄口的应用中。长期使用,透气阀可能会出现外部泄漏或湿气进入弹簧腔。
  • 每4000个周期中,会有接近1滴(0,07 cc)的油液进入外接口弹簧腔。
  • 利用Sun浮动结构减少由于过量安装扭矩或插孔/插装阀加工误差带来的内部零件粘结的可能性。

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

A sequence valve opens when the pressure at port 1 exceeds the setting of the valve. When pressures at port 1 and port 2 both exceed the setting of the valve the valve goes full open, or sequences. When this happens flow can go in either direction, just so long as port 1 stays above the setting.

Only external seals are serviceable.  Sun offers replacement seal kits for all cartridge models. The applicable kit part number can be found in the product page's Technical Data table or by using our Cartridge Seal Kit search function located under Accessories. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.
