Organization: SAE
Publication Date: 1 November 2017
Status: active
Page Count: 14
scope:

This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating:

a. Flow versus pressure drop

b. Leakage rate

c. Operating effort

d. Metering characteristics versus spool travel, pilot pressure, or electrical current

e. Relief valve characteristics

The document applies to single and multiple section hydraulic directional control valves.

This document illustrates axial, manually operated valves although the test procedure is applicable to other input forms such as rotary actuation, electric current, hydraulic or pneumatic pressure.

Performance characteristics such as metering hysteresis or dynamic response may have a significant effect on some of these tests.

Purpose

To provide a uniform procedure for measuring and reporting the operating characteristics of a hydraulic directional control valve and associated relief valve when so equipped.
