| 发明名称 | Bi-directional pressure equalization valve | ||
| 摘要 | A valve for enabling communication between a first pressure and a second pressure including a piston member arranged in a housing. The piston member is movable between an open configuration and a closed configuration for selectively enabling communication between the first and second pressures. A control assembly is included for moving the valve to the open configuration. A first net pressure area is exposed to the first pressure and operatively arranged to urge the valve in a closing direction in response to the first pressure when the valve is in a closed configuration. A second net pressure area is exposed to the second pressure and operatively arranged to urge the valve in the closing direction in response to the second pressure when the valve is in a closed configuration. A method of operating a valve system is also included. | ||

| 主权项 | 1. A valve for enabling communication between a first pressure and a second pressure, comprising: a housing; a piston member arranged in the housing, the piston member movable between an open configuration and a closed configuration for selectively enabling communication between the first and second pressures; a control assembly for moving the valve to the open configuration; a first net pressure area exposed to the first pressure and operatively arranged to urge the valve in a closing direction in response to the first pressure when the valve is in a closed configuration; and a second net pressure area exposed to the second pressure and operatively arranged to urge the valve in the closing direction in response to the second pressure when the valve is in a closed configuration. | ||
