- Scope
- This standard specifies the dimensions of the mounting surface of servo valves to ensure their interchangeability. This standard is mainly applicable to the current industrial four-port and five-port (the pilot stage provides oil separately) electro-hydraulic flow control servo valves. This standard also applies to pressure control servo valves. When used with a three-port servo valve, either work port (A or B) can be omitted. Given that there is no strict distinction in performance and/or application between servo valves and certain proportional control valves, the presence of mounting surfaces for this servo valve does not preclude the use of mounting surfaces as specified in GB/T 2574.
