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 ...
The New Revised Standard Version Updated Edition (NRSVue) is a major revision of the NRSV. A three-year process of reviewing and updating the text of the NRSV was announced at the 2017 Annual Meeting of the Society of Biblical Literature. [20] The update was managed by the SBL following an agreement with the copyright-holding NCC.
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.
Choke valve, Butterfly valve used to limit air intake in internal combustion engine. (Not to be confused with choke valves used in industrial flow control, above.) Clapper valve: a type of check valve used in the Siamese fire appliance to allow only one hose to be connected instead of two (the clapper valve blocks the other side from leaking out)
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)

Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...
The Schrader valve (also called American valve [1]) is a type of pneumatic tire valve used on virtually every motor vehicle in the world today. The original Schrader valve design was invented in 1891 and patented in the United States in 1893. [2] The Schrader valve consists of a valve stem into which a valve core is
