Extreme pressures or temperatures individually are not usually the problem, but rather their combination.

Overview
Microvalves are one the most important microfluidic components. Besides pumps and flow sensors, active valves are critical components in microfluidic systems. Today, the industry...
The heart of the control valve is the trim, especially the mating parts that throttle the stream to the demands of the controller. These valve parts are subjected to the most taxing service, and...
PISTON VALVES
Piston valves are closing-down valves in which a piston-shaped closure member intrudes into or withdraws from the seat bore, as in the valves shown in Figure 3-20 through Figure 3-24.
The fundamentals of a particular type of valve relate to its sealing characteristics, which include in-line seat sealing when closed and where applicable stem sealing which should prevent potential...
