   Copper fittings for soldered joints. Pipe fittings: 1) Copper (solder); 2) Iron or brass (threaded); 3) Brass (compression); 4) Brass (compression to solder); 5) Brass adapters. PVC fittings. A fitting or adapter is used in pipe systems to connect sections of pipe (designated by nominal size, with greater tolerances of variance) or tube ...

3. Gate valve - Wikipedia

   en.wikipedia.org/wiki/Gate_valve

   Gate valve. An electric multi-turn actuator on a gate valve. A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate faces can be parallel but ...

4. Tap (valve) - Wikipedia

   en.wikipedia.org/wiki/Tap_(valve)

   For high pressure domestic water systems this does not matter, but for low pressure systems where flow rate is important, such as a shower fed by a storage tank, a "stop tap" or, in engineering terms, a "gate valve" is preferred. Gate valves use a metal wedge with a circular face, usually the same diameter as the pipe, which is screwed into ...

5. Gatehouse (waterworks) - Wikipedia

   en.wikipedia.org/wiki/Gatehouse_(waterworks)

   Gatehouse (waterworks) The Kinzua Dam in Pennsylvania, with outlet works releasing water. A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth ...

6. Hydraulic ram - Wikipedia

   2. Free flow at waste valve 3. Outlet – delivery pipe 4. Waste valve 5. Delivery check valve 6. Pressure vessel. A simplified hydraulic ram is shown in Figure 2. Initially, the waste valve [4] is open (i.e. lowered) because of its own weight, and the delivery valve [5] is closed under the pressure caused by the water column from the outlet [3].

7. Check valve - Wikipedia

   en.wikipedia.org/wiki/Check_valve

   The water to the slide flows through a pipe which doubles as the tower holding the steps to the slide. When the facility with the slide closes for the night, the check valve stops the flow of water through the pipe; when the facility reopens for the next day, the valve is opened and the flow restarts, making the slide ready for use again.
