2. Gate valve - Wikipedia

   en.wikipedia.org/wiki/Gate_valve

   Another type of bonnet construction in a gate valve is pressure seal bonnet. This construction is adopted for valves for high pressure service, typically in excess of 2250 psi (15 MPa). The unique feature of the pressure seal bonnet is that the bonnet ends in a downward-facing cup that fits inside the body of the valve.

3. Gate (hydraulic engineering) - Wikipedia

   en.wikipedia.org/wiki/Gate_(hydraulic_engineering)

   Within the gate valve, there is a gatelike disk that moves up and down perpendicular to the path of flow and seats against two seat faces to shut off flow. The velocity of the fluid against a partly opened disk may cause vibration and chattering which will ultimately lead to damage to the seating surfaces. This is a common way that gate valves ...

4. Tainter gate - Wikipedia

   en.wikipedia.org/wiki/Tainter_gate

   The design of the Tainter gate results in every pressure force acting through the centre of the imaginary circle of which the gate is a section, so that all resulting pressure force acts through the pivot point of the gate, making construction and design easier. When a Tainter gate is closed, water bears on the convex (upstream) side.

5. Sluice - Wikipedia

   en.wikipedia.org/wiki/Sluice

   Flap sluice gate A fully automatic type, controlled by the pressure head across it; operation is similar to that of a check valve. It is a gate hinged at the top. When pressure is from one side, the gate is kept closed; a pressure from the other side opens the sluice when a threshold pressure is surpassed. Vertical rising sluice gate

6. Penstock - Wikipedia

   en.wikipedia.org/wiki/Penstock

   A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is of Scots origin, and was inherited from the earlier technology of mill ponds and watermills , with penstocks diverting pond waters to drive the mills.

7. Control valve - Wikipedia

   en.wikipedia.org/wiki/Control_valve

   Control valve: Controls flow parameters proportional to an input signal received from the central control system. Examples: Globe valve, angle valve, ball valve; Shut-off / On-off valve: These valves are either completely open or closed. Examples: Gate valve, ball valve, globe valve, angle valve, pinch valve, diaphragm valve
