FLUID EXCHANGE DEVICES AND RELATED CONTROLS, SYSTEMS, AND METHODS

Devices for exchanging properties, such as pressure, between at least two fluid streams and related methods may include pistons coupled to a valve stem. The valve stem and valve body may be configured to define a primary seal between the one or more pistons and the valve body and a secondary seal be...

Zusammenfassung:	Devices for exchanging properties, such as pressure, between at least two fluid streams and related methods may include pistons coupled to a valve stem. The valve stem and valve body may be configured to define a primary seal between the one or more pistons and the valve body and a secondary seal between the one or more pistons and the valve body. Des dispositifs pour échanger des propriétés, telles que la pression, entre au moins deux courants de fluide et des procédés associés peuvent comprendre des pistons accouplés à une tige de soupape. La tige de soupape et le corps de soupape peuvent être conçus pour définir un joint d'étanchéité primaire entre le ou les pistons et le corps de soupape et un joint d'étanchéité secondaire entre le ou les pistons et le corps de soupape.
