Valves are important devices to regulate flows, block liquids or ensure security in piping systems. There are many shapes and functions existing. We can find them in many places, to begin with households or heavy industries.

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.

Tagging

Key Value Comment Recommendation
pipeline valve Valves are usually mapped as node. This tag says it's a valve mandatory
valve <valve technology> The design of the valve recommended
location <location> The physical location of the valve, such as indoor. 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? optional
actuator <actuator technology> Mode of actuating the valve optional
sensor:position <position sensor> Position sensor design used to get the valve current status. Not fluid pressure or chemical sensor which may be installed beside the valve optional
remotely_controllable Control mode How the actuator is remotely activated to change the valve state. optional

Thermostatic globe valve
Europe

pipeline=valve
valve=globe
handle=wheel
turn_to_close=clockwise
actuator=thermostatic

A domestic globe valve installed on heating radiators. The valve opens and close depending on the delta between fluid and ambient temperatures according to spring inside

Water valves

Water valves used in water networks

Globe valve The Netherlands

pipeline=valve
valve=globe
handle=wheel
turn_to_close=clockwise
emergency=fire_service_inlet
fire_mains=dry

The valve prevent water to get out of a fire fighters riser pipe in a building. This is a typical globe valve
Butterfly valve France

pipeline=valve
valve=butterfly
actuator=electric_motor
handle=wheel
turn_to_close=anti_clockwise (written on it)
remotely_controllable=yes

This is a common valve used to regulate pressure in water mains on distribution networks. Switchable wheel allow technicians to open and close the valve so does the electric actuator on top of it.
Penstock ball valve Switzerland

pipeline=valve
valve=ball
actuator=hydraulic_cylinder
handle=no
sensor:position=mechanical
remotely_controllable=yes

Hydroelectric power plants usually got valves at top and bottom also of their penstocks carrying water down to turbines. Such a valve is mainly fully opened or fully closed depending of the plant operational status. It is located next to a pelton turbine at the end of the penstock. Here is how a ball valve closes:

Quarter-turn butterfly valve France

pipeline=valve
valve=butterfly
actuator=manual
handle=lever
turn_to_close=clockwise
sensor:position=yes

Such a valve use a movable disk to let or prevent water from passing through it. A lever handle and a sensor allow technician to change the valve state.
Valve on a fire hydrant France

emergency=fire_hydrant fire_hydrant:type=pillar pipeline=valve
valve=globe
actuator=manual
handle=wheel
turn_to_close=clockwise

A fire hydrant with a globe valve to open or close the 3 outlets

Gas safety valve France

pipeline=valve
valve=ball
actuator=hydraulic_cylinder
handle=no
operator=GRTGaz
manufacturer=Camron
location=underground
remotely_controllable=yes

The valve is actually underground and ensure safety of the rising pipeline on the background. Only its head is visible from the ground surface.

Needle valve Switzerland

pipeline=valve
valve=needle
actuator=hydraulic_cylinder
handle=no
manufacturer=Voith
location=indoor
remotely_controllable=yes

A closed needle valve designed to regulate the intake of water toward a Pelton power turbine. The opening of the needle allows the water to be directed to the turbine with the appropriate power.
Solenoid globe valve France

pipeline=valve
valve=globe
actuator=solenoid
handle=button
manufacturer=Bürkert
model=5282
material=brass
location=indoor
remotely_controllable=yes

A comon globe valve which state is modified by a solenoid. A manual button allow local operator to unlock the valve in case of solenoid failure. It is provided by Bürkert. Datasheet
