Tag:pipeline=valve

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

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 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 . 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

Examples

Domestic devices

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

Photo	Location	Tagging	Comments
	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
	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.
	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:
	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.
	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

	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.
	pipeline=valve valve=fire ref=FS 107 substance=gas	the valve referred to in the example above

Pneumatic and industrial devices

	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.
	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
