Flange
Are used to control the flow of water throughout the supply system. The proper location of valves simplifies repairs to the system, fixtures, or equipment being served.
Valves
There are usually valve at: (3)
Pipes in individual fixture or equipement
Risers
Branch
A valve in which the flow of water is cut off by means of a circular disk fitted against machine smoothed faces, at right angles to the direction of flow. The disk is raised or lowered by means of a threaded stem connected to the handle of the valve. The opening in the valves is usually as large as the full bore of the pipe,
Gate Valve
A valve in which the flow of fluid is cut off by means of a circular disc that fits over and against the horizontal valve seat. The movement of the plane of disc parallel to the normal direction of the flow of water through the orifice resulting to a tortuous passage which offers a high pressure loss.
Globe Valve
Type of globe valve that has a wide bearing surface producing good resistance to the cutting effects of scale, dirt and other kind of foreign matter found inside the pipe.
Plug type disk Valve
A type of globe valve that has a pressure tight bearing between the disc and the seat recommended for cold water supply and temperature service.
Conventional Disc Valve
A type of globe valve that is used for various types of service on oil, gasoline, steam, and hot or cold water.
Composition Disc Valve
Have a disc that is equal in size to the inside diameter of the pipe, This disc is attached to a level handle that rotates the disc, which adjust the flow of water. The main drawback to this type of valve is that the control disc is always present within the flow of water (even when fully open) so there will always be a pressure drop when using them. Its use allow for fairly precise control of flow. They typically rely on a gasket to provide a full seal, which can become a maintenance issue.
Butterfly Valve
A diaphragm valve is similar to a gate valve in that there is a wheel or know that move an element in the valve fitting, which limits the flow of water. In a diaphragm valve, the element is a diaphragm that settles down over a saddle, thus stopping water flow. The diaphragm below is a weir-type diaphragm valve, where water passes over a weir. There is also a straight-type diaphragm valve, which doesnt force water over a weir.
Diaphragm Valve
A valve that automatically closes to prevent the flow of liquid or gas in a reverse direction.
Check Valve
Three types of Check Valve
Lift Check Valve
Swing Check Valve
Spring Loaded Valve
Operates in the same manner as the globe valve. It is available in similar range of disc and seat design. It is used in making 90 degree turn in a line to reduce the number of joints.
Angle Valve
Are made with a rotating sphere that has in it. In the open position, the hole in the sphere is in line with the pipe. When closed, the hold in the sphere is perpendicular to the pipe. THe level handle operates the valve, but also seves as an indicator for whether the valve is open or closed. When the lever is parallel to the pipe, the valve is open. Its use do not allow for precise flow control because they usually have positive stops (0, 45, 90 degrees), but they do provide a very good seal in the closed position.
Ball Valve
A valve located at the end of a water pipe through of which water can be drawn from or held within the pipe.
Faucet
is a valve mechanism which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits.
Pressure Relief valve
pressure balance valves are used to maintain a constant temperature of water in domestic showers or bathtubs. A diaphragm within the valve allows the operator to set mixing of hot and cold water, however in the event of a pressure drop of cold water (for instance , if a toilet neary is flushed), the diaphragm will shift to limit an excessive flow of hot water. Many jurisdictions require pressure balanced valves in domestic bathrooms and showers to prevent accidental scalding.
Pressure Balanced Valve
is used on cold water systems, heating systems, compressed air lines, and other pipe lines with excessive pressure.
Safety Valve
Is a device, which discharges a predetermined quantity of water into fixtures for flushing purposes and is actuated by direct water pressure.

Illustrate and detail water supply connection from water main to water distributing pipes
is located at the lower end of the pump used to prevent loss of priming the pump. It is sometimes referred to as retention valve.
Foot Valve
Is inserted into the water main. It serves as a control of the water service, And also serve as a shut off, when the service is disconnected.
Corporation Stop
is installed between the curb and the sidewalk line accessible to cast iron stop box equipped with removable cover. It serves as control stop of the service between the curb and building. It shut off water supply in case the basement becomes flooded.
Curb Stop
A valve placed at the street side of the water meter and serves as a controlling device for the building installation.
Meter Stop
Are used in hydronic heating and colling systems to control the flow of water of steam. For instance, they may be provided in different rooms, different floors, or different dwelling units so that each space can have local control over the heating or cooling. In most applications, zone valve are electrically controlled and are connected to a thermostat so that automatic control is acieved.
Zone Valve
aLMOST ANY TYPE OF VALVE CAN BE LOCKED TO AVOID ACCIDENTAL OR INTENTIONAL OPENING OR CLOSING. hOWEVER, VALVE WITH LEVER-TYPE HANDLES ALLOW FOR MORE SECURE LOCKING CONTROL. LOcking valves provide aligning holes that a lock can be passed through to stop rotation of the handle. There are also locks designed to be attached to non-locking valves to prevent adjustment.
Locking Valve
a type of gate valve in which the valve stem and disk rise together when valve is open
Rising Stem Valve
a type of gate valve in which the valves stem doesnt rise together when valve is open.
Non-rising Stem Valve
The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe, plumbing fixture, appliance or appurtenance conveying waste to the flood level rim of the receptor.
