This part of ISO 14617 specifies graphical symbols for valves and dampers in diagrams, including symbols for general-purpose valves, those used in fluid power systems and hygienic valves used in the food and pharmaceutical industries.
Pressure Reducing Valve: This symbol represents a valve that is used to reduce the pressure in a hydraulic system to a specific level. It is commonly used in applications where a lower pressure is required for certain components or processes.

Pressure reducing valve symbols look very similar to those for pressure relief valves. This is because the valves work in similar ways except that the pressure sense line feeds from downstream of the reducing valve instead of upstream as in the relief valve.
21 Μαρ 2019 · In this edition of Hydraulic Symbology, I’m going to cover the four primary pressure valves; the relief valve, motion control valve, sequence valve and reducing valve. Each is based on the same square symbol but are used quite differently in both circuits and real-life function.
Pressure control valves: These valves regulate the pressure within a hydraulic system and are represented by symbols such as a spring or adjustable screw. Flow control valves: These valves control the rate of fluid flow in a hydraulic system and are represented by symbols such as an adjustable restrictor or a variable orifice.
