產品描述 :
HiPerSeal®是一種U型鐵氟龍內裝特殊彈簧的高性能彈簧密封件，俗稱彈簧油封或彈簧致動油封。鐵氟龍彈簧油封是由適當的彈簧力加上系統流體壓力，將密封唇(面)頂出而輕輕壓住被密封的金屬面以產生優異密封的效果。彈簧的致動效應可以克服金屬配合面的輕微偏心以及密封唇的磨耗，而持續保有預期的密封性能。它能利用各種特殊彈簧來克服鐵氟龍或其他高性能橡膠塑料的彈性問題，開發出可取代絕大數應用於靜態或動態（往復或旋轉運動）的密封件。而彈簧可因應不同的使用環境，選用不鏽鋼、Elgiloy®、Hastelloy® 等，故可應用於各種高溫腐蝕流體的場合。我們提供廣泛的彈簧選擇，其中包含斜圈彈簧(C型彈簧 - Canted Coil Spring)、螺旋彈簧(H型彈簧 - Helical Spring)、懸臂彈簧(V型彈簧 - Cantilever Spring)。

產品描述 :
Coupling elements of HYDROKOMP are made of stainless materials. This enables the elements to be used for all fluids and gases that are not aggressive. Special designs eg. for water steam or other media are available on request. HYDROKOMP offers coupling elements for two different operating modes depressurized coupling or pressurized coupling. The elements for depressurized coupling can be coupled pressurized up to 25 bar, if the specified volume flow is not be exceeded. When using higher operating pressure there ockures a risk of demaging the soft seal in the check valve as the result of high flow velocities of the fluid. This means for coupling of air up to 10 bar there should be always used the coupling elements for depressurized coupling. This also applies when the coupling process is initiated pressurized. The elements which can be coupled pressurized may be coupled up to the maximum specified operating pressure on one side and / or on both sides.

產品描述 :
截止式換向閥屬於換向閥類。 作為錐形閥，它在閉合狀態時是無洩漏密封的。
ROLV 型截止式換向閥有 3/2、4/2 和 4/3 截止式換向閥可供選擇，採用不同的接頭類型。 專利的安裝結構由兩個部分組成，一個是帶有閥芯的圓形主閥，一個是過渡板，其設計可用於採用規定規格 NG 6 標準連接圖的板式安裝或用於直接的管接。
根據功能要求和過渡板，可整合例如單向閥、一個（執行元件側）節流孔和/或單向節流閥之類的附加元件。 ROLV 型可以在功能閥片類型 BA中與其他類型的閥組合。

產品描述 :
Swing clamp cylinders release the clamping point on the workpiece. With this, it is easy to change the workpiece. This hydraulic swing clamp cylinder operates as single-acting or double-acting traction cylinder, whereas part of the stroke is used to rotate the piston. The model with 0° swing angle operates only vertical as traction cylinder.
To guarantee a long lifetime the cylinders have an integrated metal wiper as standard. For oil supply, the cylinders are equipped with threaded port and manifold port with O-ring for drilled channels. You can select between right or left turning models with various standardized swing angles. The integrated overload protection protects the swing mechanism from damage due blockage of the rotation or improper assembly of the clamping arm.
For any risk of exceeding the permitted volume flow a throttle check valve must be interposed into the oil supply line. Counter-hold the clamping arm when tightening or loosening the counter nut in order to prevent torque transfer to the piston rod and to avoid damage to the ball guide. Variations with 0°, 30°, 45°, 60° and 90° swing angles are available. The permitted operating pressure is depending from the clamping arm length.
