*2: The same applies to the seal material of nitrile rubber and fluoroelastomer.
*3: The conversion formula between the effective cross-sectional area S and the sonic conductance C is S ≈ 5.0 × C.
*4: Please refer to the following for the pilot pressure of NO type and double-acting type.

 

■Pilot pressure
Please use the pilot pressure within the specified range. In particular, set the pilot pressures for the NAB series of the NO type and double-acting operation type as shown in the graph below.
If it is used below the set range of the graph, a seal failure will occur, and if it is used above the set range, the durability will decrease.
If the pilot pressure cannot be controlled, it is recommended to select the model number of the NC type.
