液压阀外壳

Machining requirements

• Fluctuating cast allowance situation
• Heavily interrupted cuts
• Avoid ring formation during boring and ensure safe chip removal from the housing
• Avoid macroscopic flaws on the control edges in the boring process
• Very high demands on form and position tolerance
• Constant stock removal before honing
• Take part variance and limited tool storage places in the machining concept into account

流体的流动方向由控制滑块（Spool）沿着控制刃口的相对运动所控制。

Compensator bore

Compensator bore

Despite different loads on agricultural and construction machinery, the volume flow for the lifting and lowering speed on an excavator shovel, for example, must remain constant. If a low load is present, the spring-preloaded pressure compensator releases a smaller cross section, to keep the volume flow constant. With high loads, a larger cross-section is released. The working speed of the hydraulic cylinder connected to the excavator shovel thus always remains the same.
