Patent ID: 8439073

Claim:
A high temperature gate valve, comprising: a valve body formed to define first and second ports and an exit, each of which has a length-wise dimension greater than a height-wise dimension at respective distal ends of the first and second ports and the exit; and a door, having a length-wise dimension greater than a height-wise dimension, coupled to the valve body to occupy and move around a hinge assembly between positions at which the door prevents fluid communication between one of a proximal section of the first port or a proximal section of the second port and a proximal section of the exit and intermediate positions at which fluid communication between the first and the second ports and the exit is permitted, the respective proximal sections and the respective distal ends of the first port, the second port and the exit being defined at opposite ends of each, and the length-wise dimensions of the valve body and the door being directed radially away from the hinge assembly and the height-wise dimensions of the valve body and the door being directed along a longitudinal axial of the hinge assembly, wherein the valve body comprises: a first body portion formed to define first and second openings and the exit; a closure, which is sealed to the first body portion at the first opening and formed to define the first port at the first opening; and a second body portion, which is sealed to the first body portion at the second opening and formed to define the second port at the second opening, wherein an angle formed between the lengthwise dimensions of the first port and the exit is greater than an angle formed between the first and second ports.
