SQBB : 自动跳合 , pilot-operated, 平衡滑阀  顺序  阀
技术特性 [ + ]

自动跳合顺序阀在进口(口1)压力超过阀设定时全开并保持打开状态,产生从口1到口2(顺序口)的自由油路。口1压力设定与外泄口(口3)相关。只要口1压力超过口2压力,阀就会保持打开状态。欲重新设定此类阀,口1压力必须降至阀的设定值之下,口1至口2的液流必须停止并且口2压力必须等于或大于口1压力。

  • 不能用在负载锁紧应用中。
  • 口3处的压力直接以1:1的比例增加到阀的设定值上,口3处的压力不能超出5000 psi(350 bar)。
  • 如应用在系统的驱动端侧,通过阀的液流必须停止,阀才能回座。如果应用在一个系统的泵端侧,泵必须关闭,阀才能回座。
  • 所有3口顺序阀在尺寸和功能上可互换(如:给定的外形结构尺寸阀拥有相同的流道,相同的插孔)。
  • 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.
