*2: The seal material is the same for both nitrile and fluoroelastomer.
*3: The conversion between effective cross-sectional area S and sonic conductance C is S ≈ 5.0 × C.
*4: For pilot pressure of the NO type and double operation type, please refer to the information below.
■ Pilot pressure
Use the pilot pressure within the specified range. In particular, set the pilot pressure for the NO type and double operation type of the NAB series as shown in the following graph.
If used below the setting range of the graph, seal failure may occur; if used above the setting range, durability will decrease.
If the pilot pressure cannot be controlled, we recommend selecting the NC type model.
