What this standard covers

This standard specifies the size of the servo valve mounting surface to ensure interchangeability. This standard applies to the current industrial port with four and five-port (pilot stage to provide oil alone) electro-hydraulic servo valve flow control. This standard also applies to the pressure control servo valve. For three servo valve port, you can omit any one working port. In view of the servo valve is no strict distinction between the valve performance and/or application, the presence of the servo valve does not exclude the use of the mounting surface such as GB/T 2574 as specified in the mounting surface with some proportional control.
