Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...
This gate type was primarily used to purposely inundate certain regions, for instance in the case of the Hollandic Water Line. Nowadays this type of gate can still be found in a few places, for example in Gouda. A fan gate has a separate chamber that can be filled with water and is separated on the high-water-level side of the sluice by a large ...
Slide gate valve: Ideal for handling dry bulk material in gravity flow, dilute phase, or dense phase pneumatic conveying applications. Similar to a sliding line blind valve, but the latter is for higher-pressure applications; Slide valve: used in early steam engines to control admission and emission of steam from the piston
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 ...
Gate valve Control valve with a solid plate operated by a handle and screw mechanism. Rotating the handle moves the plate into or out of the waterway. (See also hydrant gate) [4] Gravity tank Water storage tank for fire protection; arranged above protected area to provide flow of water by gravity when needed. Green line a garden hose. Fire grenade
Cylinder, with slide valve removed to show ports A double-acting slide valve cylinder. Steam enters via the steam port SP, and is admitted by the slide valve SV through the upper passage S to push down the piston P. At the same time, exhaust steam from below the piston passes back up the lower passage S, via the valve cavity, to exhaust E. As ...
Editor's note: The University of Georgia announced that Kirby Smart's father, Sonny Smart, died early Saturday morning. By almost any measurement, Georgia's Kirby Smart is one of the best coaches ...
Additionally, unlike conventional control valves the sleeve valve increases flow incrementally, i.e. 10% increase in stroke leads to a 10% increase in flow. Sleeve valves are adaptive to system or consumer requirements. The sleeve valve is designed to meet the requirements and allow for a wide range of variability of function.
