Pipeline valves proposal
Status: Draft (under way)
Proposed by: fanfouer
Tagging: pipeline=*
Applies to: node
Definition: Propose to improve pipeline valves mapping and description with valve=*
Drafted on: 2017-12-19



It is proposed to complete the pipeline and waterway valves tagging with the following tags :

  • valve=*
  • List to be continued shortly

There is no point to deprecate any existing tag here.
Valves have been mapped for years in OSM and this current proposal only add tagging details about them.
This proposal focus on tags to use if, and only if, data is available. It does not assume all data can be publicly known but provide a consistent model to add it to the map if possible, without any pipeline operator help.

How to map

Pipeline valve datasheet.jpg

First of all, don't go inside private or restricted perimeters if you're not invited to do so please, some valves may not be safely accessible and you may expose yourself to multiple hazards.
Public information or aerial imagery will help to see outdoor pipeline facilities safely.

On every valve device found and on a man_made=pipeline way (not surrounding building, not fence), add a node and put some tags described below like mandatory pipeline=valve.
Use location=* to give information about its position and valve=* to let us know about its mechanism.

High detailed information may be found on valves themselves. A complete datasheet as exposed beside gives many figures on the device capabilities and structure.
We basically need nominal diameter, valve mechanism but manufacturer=* and start_date=* may also be completed.
Nevertheless, you may not be able to took picture of those plates and as a reminder : don't go inside restricted perimeters to get the one you couldn't unless invited


Key Value Comment Recommendation
pipeline valve Valves are usually mapped as node. This tags says it's a valve mandatory
valve <valve technology> The design of the valve, mainly inspired by the definitions of this proposal (see rationale) recommended
location <location> The physical location of the valve, such as indoor. See below for possible values. recommended
diameter <nominal diameter> The nominal diameter of the valve in millimeters according to ISO 6708 optional
operator <operator> Name of the company that operates the valve. optional
manufacturer <Manufacturing company> Name of the company that built the valve optional
ref <reference> Abbreviation / number of the valve. optional
turn_to_close clockwise or anti_clockwise Direction of rotation wheel to close the valve. This is common to handle and actuator optional
handle <handle model> Does a handle is available on the valve? See below for possible values optional
actuator <actuator technology> Mode of actuating the valve. See below for possible values optional
remotely_controllable Control mode How the actuator is remotely activated to change the valve state. optional

Valve designs

Valves may have specific design inside a given network to fulfill a function. The design is visible on the ground and doesn't correspond to the usage or function of the valve.

Valve actuators

Actuators allow to modify the valve state, eventually open or close it completely with or without human action needed.

List of possible actuator=* values
Key Value Comment
actuator manual The most common actuator : human hands
electric_motor An electric motor is used to change the valve state
pneumatic_cylinder A cylinder powered by pressurised air change the valve state
hydraulic_cylinder A cylinder power by pressurised fluid (mainly oil) change the valve state


Water valves

Oil & gas valves
