Hydraulic fluid power — Four- and five-port servovalves — Mounting surfaces

Specifies the dimensions of surfaces on which servovalves are mounted in order to ensure interchangeability. Applies primarily to electrohydraulic flow-control servovalves. In addition, may be used for pressure-control servovalves. If the valve is used in a three-port application, either service port (A and B) may be omitted.
