Abstract

A fluid valve use in a turbomachine in a high temperature location includes a fluid inlet, a fluid outlet, a fluid circuit defined between the fluid inlet and the fluid outlet, and a solenoid including a solenoid casing. The solenoid is disposed between the fluid inlet and fluid outlet. The solenoid is configured to move a valve member between a closed position, at least one partially open position (e.g., any number of suitable positions), and a fully open position to selectively meter fluid flow through the fluid circuit. The fluid valve can include a valve casing, wherein the solenoid and valve member are disposed in the valve casing.
