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 ...
Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, a flexible diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic, metal, wood or other materials depending on the intended use.
When using a gate, one thing that is used in certain applications such as manufacturing, mining, and others is the gate valve. Fluids will run through the valve to help lubricate the moving parts of a machine, transmit power, close off openings to moving parts, and to assist evaporating the amount of heat coming through.
Globe valve. A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. [ 1 ] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
Christmas tree (oil well) Oil well Christmas tree. In petroleum and natural gas extraction, a Christmas tree, or tree, is an assembly of valves, casing spools, and fittings used to regulate the flow of pipes in an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well, and other types of well.
Pinch valve, for slurry flow regulation and control. Piston valve, for regulating fluids that carry solids in suspension. Piston valve (steam engine) Plug valve, slim valve for on–off control but with some pressure drop. Solenoid valve, an electrically actuated valve for hydraulic or pneumatic fluid control.
Valve actuator. Electric actuator (blue cylinder) on a valve in a power plant. A black handwheel is visible on the actuator, which allows manual positioning of the valve. The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator.
Ring jet valves are similar to fixed cone valves, but have an integral collar that discharges water in a narrow stream. They are suitable for heads up to 50 m. They are suitable for heads up to 50 m. Jet flow gate , similar to a gate valve but with a conical restriction prior to the gate leaf that focuses the water into a jet.
