Flanged Gate Valve: What is it?

Print anything with Printful



A flanged gate valve has integral flange plates at each end, allowing it to be easily added to existing pipe flanges. It features a circular disc that controls fluid flow and is commonly used in industrial settings. The valve can be mounted by aligning the holes in the flanges and tightening bolts. It is typically made of stainless steel, cast iron or brass.

A flanged gate valve is a conventional gate valve that includes a pair of integral flange plates at the ends of the valve body. This allows the valve to be added to existing pipe flanges in a standardized system with minimal effort. A gate valve is a type that features a circular disc that is raised or dropped within a tight-fitting chamber to allow or restrict fluid flow through the valve. Flange plates are typically flat, round plates mounted at right angles to the fluid flow path at either end of the valve body. These plates have a row of holes around their circumference through which the mounting bolts are inserted.

The gate valve is a member of the multi-turn valve family and one of the most commonly used valve types in a myriad of industries. They consist of a round, flat disc or gate valve, which is connected to a threaded screw type valve stem. At the end of its stroke, the disc shuts off the flow of fluid through the valve chamber. When the valve stem is rotated, the valve plug lifts to open the flow path.

A flanged gate valve is a specific type that includes a pair of flanged discs, one on each end of the valve body. These are typically open-center round plates cast as integral parts of the valve body. The discs are drilled with a row of holes located around their circumference which are used to mount the valve. These discs allow the flanged gate valve to be mounted on existing flanges in standardized piping systems. If, however, the valve is to be fitted to a non-standardised flange, a range of adapters are available which will assist with installation.

To mount the flanged gate valve, simply place it on an existing flange and rotate it until the holes of the two flanges align. Bolts are then inserted through holes in both flanges and tightened to secure the valve. The process is then repeated with the tube exiting the other end of the valve. This non-permanent mounting method is cost effective and efficient, allowing for quick and easy valve replacement or relocation.

The Flanged Gate Valve is typically used on large, high pressure systems in industrial and manufacturing environments. Valve flanges may have a simple design or include a ring flange groove for the inclusion of additional sealing rings. Flanged gate valve is generally constructed of stainless steel, cast iron or brass.
