低压侧, 3位, 热油梭阀
流量: 20 gpm80 L/min. |
插孔: T-32A
技术特性 [ + ]
低压侧(热油)梭阀可以将闭式油路系统中低压侧的热油疏散出去。当两个工作口(口2和口4)的压力相等,此阀在弹簧对中作用下处于所有油口都堵住的中位。当两个工作口(口2和口4)中的任何一个口处于较高压力,另一个口便会与公共口接通(口3)。
- 阀芯采用了液压制,可消除机械冲击防止潜在的内部损坏。
- 液压制动需要从高压侧油口(2口或4口),提供小量的油液流向公共口3。
- 由于是液压制动,所以它的另一个特性是,热油溢流压力设定需要在中位状态下进行。
- 注意:低压力切换阀可能被补油泵的压力切换。所以在使用时请格外小心。
- 虽然这种阀采用的是4口的插装孔,但是鼻尖口(1口)是不使用的。
- Sun浮动式的结构可以最大限度地减少由于过大的安装扭矩以及孔型加工的误差所造成的干涉现象。

Direct acting valves are used to prevent over pressure and pilot operated valves are used to regulate pressure. If you are unsure, use a direct acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
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.
