MIL-V-24722 - VALVE AND SUBPLATE, SERVO FLOW-CONTROL, ELECTROHYDRAULIC, GENERAL SPECIFICATION FOR
June 15, 1990 - NPFC

This specification covers the requirements for electrohydraulic, flow-control servovalves and their associated subplates. This type of valve will be installed into a closed-loop, position control servosystem. The valves are designed for either standard or quiet...

ISA 75.11 - Inherent Flow Characteristic and Rangeability of Control Valves
January 1, 1985 - ISA

The scope of this standard is to define the statement of typical control valve inherent flow characteristics and inherent rangeabilities, and to establish criteria for adherence to manufacturer-specified flow characteristics.
