High Pressure Valve Stems

Involving a high degree of activity and exertion; stressful

(of a salesperson or sales pitch) Employing a high degree of coercion; insistent

High pressure science and engineering is studying the effects of high pressure on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure.

A high-pressure area is a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment. Winds within high-pressure areas flow outward due to the higher density air near their center and friction with land.

Involving or using much physical force

hard-hitting: aggressively and persistently persuasive; "a hard-hitting advertising campaign"; "a high-pressure salesman"

A valve stem is a self-contained valve which opens to admit gas to a chamber (such as air to inflate a tire), and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, or both, to prevent the gas from escaping.

(Valve stem (engine)) A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve guide.

(Valve stem (valve part)) A valve is a device that regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but are usually discussed as a separate category.

Twin Engines inside the Pump-House Station

1873 Fall River Water Works URBEX Adventure (Massachusetts) "Massive Twin Engines inside the Pump-Station House" "The first engine was built in 1873 by the Boston Machine Company, and put in Operation January 5th, 2874, the first water being supplied to the city on January 8th. The engine is a double horizontal condensing engine, similar to the engines at Boston Highlands, which were built by the same company, and consists of two pumps 16 inches in diameter, and two stem cylinders 28 inches in diameter, both cylinders and pumps having a stroke of 42 inches and working from one crank-shaft with one fly-wheel, 15 feet in diameter, and weighing 15 tons. The engine possesses advantage--which on several occasions, while the community was dependent on its unassisted efforts, has proved very useful and essential--the fact that its two parts are symmetrical, and although designed to work together, capable of being run separately, and one half stopped if it is necessary to make any repairs or to adjust or replace the valves. This engine pumps directly into a 24-inch force-main, extending from the engine-house to the center of the city at the corner of Main and Bedford streets, a distance of a mile and three quarters, and this force-main supplies low-service--that is, all those portions of the city which can be satisfactorily supplied with an adequate pressure from a reservoir, which is intended to be constructed at some future time on the hill near the pumping station, where the elevation of the highest point is 256 feet above tide-water."
