Important information on hydraulic fluids: For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Bio-degradable and flame-resistant: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system.

注意：

T 口的液压背压以 1:1 的比例叠加到通过调节装置设定的阀响应压力上。

示例：

通过弹簧预紧调节阀的压力（见“产品描述”第 2 项）p spring = 200 bar

T 口的液压背压：p hydraulic = 50 bar

⇒ 响应压力 = p spring + p hydraulic = 250 bar
