直动式 顺序阀 无逆流单向阀

流量: 30 gpm120 L/min. | 插孔: T-2A
SXEA : 直动式 顺序阀 无逆流单向阀
技术特性 [ + ]

直动式顺序阀将在进口(口1)压力超过阀的设定之后向次级油路供油。顺序阀的设定将控制与外泄口 (口3)压力相关的口1压力。

  • 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)。
  • 虽然先导流量为零,口3(外泄)必须连接以维持控制腔的压力参考。如果口3被堵住,控制腔积聚的密封泄漏油液有可能使阀失效。
  • 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)。
  • 适合使用在负载锁紧应用中。
  • 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.
