Miniature Fittings Enhance Airline Beverage Service

Beverage service aboard commercial aircraft has changed little since the 1950s. Flight attendants wheel a mobile service cart filled with metal cans to each passenger. With an increasing focus on cost and weight reductions, this traditional method will soon be replaced with a new system from Sterling Beverage Systems, Newnan, Ga. Sterling has designed and […]

Material Selection for Valves: Focus on the Application

Given the huge body of information regarding the properties of materials commonly employed in valve bodies, seals, and O-rings, the material selection process is becoming a routine exercise. The challenging part of determining material choice is actually verifying that the chosen material best fits the application. Most material selection problems at Beswick Engineering, Greenland, N.H., […]

Small Things Are Big in Fluid Power

This Article Originally Was Published On By Rob Spiegel, Senior Editor, Automation & Control Trends in industrial fluid power reflect the overall direction of industrial electronics. Equipment is getting smaller, smarter, and more efficient. The megatrends in hydraulics and pneumatics include miniaturization, environmental (meaning both clean and ever more efficient), and greater intelligence via electronic […]

The Basics of Pressure Relief Valves

THE HISTORY OF PRESSURE RELIEF VALVES Pressure relief valves (safety relief valves) are designed to open at a preset pressure and discharge fluid until pressure drops to acceptable levels. The development of the safety relief valve has an interesting history. Denis Papin is credited by many sources as the originator of the first pressure relief […]

O-ring Guide

The leak-tight captured o-ring face seal was first incorporated into a variety of miniature 10-32 threaded pneumatic fittings in the late 1960s and early 1970s by Paul Beswick, a registered professional engineer and founder of Beswick Engineering. This novel approach to fluid power design, which was well ahead of its time, began a culture of […]
