寶德6223型伺服輔助式比例閥/BURKERT6223型比例閥
寶德6223型伺服輔助式比例閥的主閥般來說和換向閥樣是滑閥結構，只不過閥芯的換向不是靠電磁鐵來推動，而是靠前置閥輸出的液壓力來推動，這點和電液換向閥比較相似，只不過電液換向閥的前置閥是電磁換向閥，而伺服閥的前置閥是動態特性比較好的噴嘴擋板閥或射流管閥。也就是說，伺服閥的主閥是靠前置閥的輸出壓力來控制的，而前置閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置閥就不能輸出足夠的壓力來推動主閥芯動作。而我們知道，當負載為零的時候，如果四通滑閥*打開，p口壓力=t口壓力+閥口壓力損失（忽略油路上的其它壓力損失），如果閥口壓力損失很小，t口壓力又為零，那么p口的壓力就不足以供給前置閥來推動主閥芯，整個伺服閥就失效了。
