双向, 直动式溢流阀 - 先导流量
直动式,先导级溢流阀结合了背靠背的单向阀。此阀常用于2个先导控制式阀的远程压力控制或驱动器的两端热溢流。由于此类阀流量能力仅限于先导级别,因此它们应该与其它需相匹配先导流量要求的阀一起使用。
- 背靠背的单向阀可防止两个正在远程控制阀之间发生串扰。
- 一个调节可以控制两个阀。
- 单向开启压力为15 psi (1 bar)。
- 口3处的压力直接加到阀的设定上。
- 适合负载锁紧应用。
- 热溢流表明此阀可以防止流体热膨胀引起的过压。
- 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。

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.

One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.
There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.
- 对于采用O控制(旋钮调节,带面板锁)的系列1插装阀,面板上需要留一个直径0.75 in. (19 mm)的孔。
