91Mitral valve — Anterior (frontal) view of the opened heart. White arrows indicate normal blood flow. (Mitral valve labeled at center right.) …
92Transmission control unit — A transmission control unit or TCU is a device that controls modern electronic automatic transmissions. A TCU generally uses sensors from the vehicle as well as data provided by the Engine Control Unit to calculate how and when to change gears in …
93Pinch Valve — is a full bore or fully ported type of control valve. No obstruction to flow passage. Major components of a pinch valve consists of body and a sleeve. The sleeve will contain the flow media and isolate it from the environment hence reducing… …
94Pilot valve — A pilot valve is a small valve that controls a limited flow control feed to a separate piloted valve. Typically, this valve controls a high pressure or high flow feed. Pilot valves are useful because they allow a small and easily operated feed to …
95flow-control valve — A fluid powered valve that controls the volume or the direction of fluid flow. Flow control valves, like check valve and selector valves, are normally used along with pressure control valves in fluid power systems. See flapper valve …
96Blowoff valve — A blowoff valve (BOV) or dump valve is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blowoff valves relieve the damaging effects of… …
97Plug valve — Plug valves [American Petroleum Institute Standards: API 6D Pipeline Valves ; API STD 599 Metal Plug Valves ] are valves with cylindrical or conically tapered plugs which can be rotated inside the valve body to control flow through the valve. The …
98Choke valve — A Choke valve is a type of valve designed to create choked flow in a fluid. Over a wide range of valve settings the flow through the valve can be understood by ignoring the viscosity of the fluid passing through the valve; the rate of flow is… …
99overrun control valve — A valve in a crossover pipe between the compressor suction and discharge sides of some turbocharger systems. When the manifold pressure drops, as during deceleration, the overrun control valve opens and allows compressed air to circulate through… …
100Kingston valve — A Kingston valve is a type of valve fitted in the bottom of a ship s fuel, water and ballast tanks. Named after its inventor John Kingston (1786 1847)an English engineer. [ Building the Steam Navy: Dockyards, Technology and the Creation of the… …
