Abstract
A valve includes a first seal seat, a second seal seat, and a flow path for a fluid across the first seal seat. A seal is sealed against the first seal seat and the second seal seat. An actuator is adjacent the first seal seat and is operable to deflect the seal and thereby permit flow of the fluid through the flow path. the seal defines a through-passage fluidly connecting the first seal seat to a pressure-balance cavity behind the seal at the second seal seat.
Claims16
A valve comprising:
- a first seal seat, a second seal seat, and a flow path for a fluid across the first seal seat;
- a seal sealed against the first seal seat and the second seal seat;
- an actuator adjacent the first seal seat and operable to deflect the seal and thereby permit flow of the fluid through the flow path;
- and
- the seal defining a through-passage fluidly connecting the first seal seat to a pressure-balance cavity behind the seal at the second seal seat.

A valve comprising:
- a first seal seat, a second seal seat, and a flow path for a fluid across the first seal seat;
- a seal having a closed state in which the seal is sealed against the first seal seat to block flow of the fluid through the flow path and an open state in which the seal is deflected with respect to the first seal seat to permit flow of the fluid through the flow path, the second seal seat being sealed against the second seal seat in both the open state and the closed state;
- an actuator adjacent the first seal seat and operable to deflect the seal to move from the closed state to the open state;
- and
- the seal defining a through-passage fluidly connecting the first seal seat to a pressure-balance cavity behind the seal at the second seal seat, the through-passage permitting the fluid to flow to the pressure-balance cavity and create a pressure-balance across the seal in the closed state.
