Title:
流体調節デバイス
Document Type and Number:
Japanese Patent JP5307122
Kind Code:
B2
Abstract:
A gas regulator comprises an actuator and a valve body, wherein the actuator includes a valve disc with a cylindrical shroud that extends beyond the valve disc to direct the flow of fluid through the regulator toward the outlet of the valve and away from the actuator. This configuration advantageously reduces the amount of pressure drop experienced by the actuator during normal operation, thereby minimizing a phenomenon known as "droop." At least in one embodiment, the shroud can be adjustable and/or removable to allow the regulator to be tuned for specific applications.
