An angle seat piston valve is a pneumatically-controlled valve with a piston actuator providing linear actuation to lift a seal off its seat. The seat is set at an angle to provide the maximum possible flow when unseated. Angle seat piston valves are particularly suited to applications where high temperatures and large flow rates are required ...
Valves are available in several types, based on design and purpose: Gate, plug, or ball valves – Isolation; Globe valve – Throttling; Needle valve – Throttling, usually with high precision but low flow; Butterfly or diaphragm valves – Isolation and throttling; Check valve – Preventing reverse flow (non-return)
The Ford Duratec V6, is an aluminum DOHC V6 engine with a 60° bank angle introduced in 1993 with the Ford Mondeo.The primary engineering came from Porsche, [1] who was developing this engine before selling the engineering to Ford, and Cosworth, who helped with cylinder head manufacturing. [2]
An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. [1] They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. [ 2 ]
Within the engine, Mitsubishi used an offset angle crankshaft that reduces friction, therefore noise and vibration, allowing the engine to run smoothly and quietly at all engine speeds. [ 1 ] [ 11 ] To meet the requirements of global emissions standards, Mitsubishi developed a new catalyst system that combines a Diesel Oxidation Catalyst (DOC ...
The engine weight has been reduced by 12 kg (26 lb) compared to the 4G63, even with the addition of a timing chain instead of a belt and MIVEC continuous variable valve timing on both the intake and exhaust camshafts (the 4G63 had MIVEC valve timing & lift switching type on the intake only). A revised turbocharger offers up to 20-percent ...

Ports are obstructed by the valve member or disc to control flow. Valves most commonly have 2 ports, but may have as many as 20. The valve is almost always connected at its ports to pipes or other components. Connection methods include threadings, compression fittings, glue, cement, flanges, or welding.
