Patent number: 11835973Abstract: A fluid pressure control apparatus includes a proportional solenoid valve having a solenoid portion and a valve portion operatively connected between a fluid inlet port and a fluid outlet port fluidly coupled to a pressure sensor. An electronic controller receives a first signal from the pressure sensor, receives a second signal corresponding to a pressure set point, and outputs a control signal to the solenoid valve. A flameproof/explosion proof or pressurized/purged enclosure houses the electronic controller and the solenoid portion of the solenoid valve, and a manifold block mounted to the enclosure covers and closes an opening of the enclosure. The manifold block includes internal passageways connecting the valve portion of the solenoid valve between the fluid inlet port and the fluid outlet port. The pressure sensor is arranged outside the enclosure, with the first signal from the pressure sensor being conducted into the enclosure via a fluid-tight electrical feedthrough.Type: GrantFiled: March 19, 2021Date of Patent: December 5, 2023Assignee: Siemens AktiengesellschaftInventor: Piotr Strauch
