ANSI Globe Valve
ANSI globe valves product types include gate valves, butterfly valves, globe valves, and others. Their structural design accommodates high-temperature, high-pressure, and complex operating conditions. Pressure ratings range from 150 to 2500 pounds, with operating temperatures reaching up to 550°C.
Overview
Introduction:
The body of an ANSI globe valve typically consists of a spherical shape with inlet and outlet ports, along with a central passageway. It's designed to handle high-pressure applications and can be made from materials like cast iron, cast steel, stainless steel, or bronze.
-The bonnet is the top portion of the valve body that houses the stem and provides a seal to prevent leakage. It can be bolted, screwed, or welded to the valve body.
-Inside the valve body, there's a disc or plug that moves up and down to regulate the flow of fluid through the valve. When the valve is open, the disc is lifted away from the seat, allowing fluid to pass through. When the valve is closed, the disc makes contact with the seat, preventing flow.
-The seat is a sealing surface located at the bottom of the valve body. When the valve is closed, the disc presses against the seat to create a tight seal and prevent leakage.
-The stem connects the handwheel or actuator to the disc inside the valve body. When the handwheel or actuator is turned, it moves the stem, which in turn raises or lowers the disc to control the flow of fluid.
