调压阀 德派DOPAG

德派DOPAG调压阀用于将材料输入压力降低至所需要的操作压力。除了精准调节材料压力外，调压阀还可抵消柱塞泵的相互作用所引起的压力波动。这种压力波动会使压力短时间内降低，并导致材料流量略微下降。如果要求的出胶（油）量较少，这可能会影响产品质量，尤其是要求出胶（油）量一致的应用。德派调压阀可用于处理粘度5000至500000mPa s的材料，有两种不同的结构：

• 柱塞式调压阀
  该类型调压阀适用于处理润滑脂、润滑油以及单组份和多组份硅胶等。阀内空间通过弹簧片密封圈加以密封。

• 隔膜式调压阀
  该类型调压阀大多数适用于活性的、对湿度敏感的材料，由于球阀和阀座采用钨合金材质，因此亦适用于具有磨损性的材料，如环氧树脂、聚氨酯以及其他材料。阀内空间通过弹簧片密封圈加以密封。

Material pressure regulators with piston

Material pressure regulators reduce the pressure of the delivered material to the required working pressure. Apart from reducing pressure (main function), these valves compensate the pulsations which occur during the material delivery with piston pumps due to the changeover position of the pump.

Such pulsations would cause a short-time drop of pressure and lead to a slight reduction of the material flow. In case of small metering quantities, this might impair product quality as especially for such applications an absolutely consistent material flow must be ensured.
