Flanged Brass Isolation Valve
JX-0441
DN20
A brass isolation valve with a flange is one of the most critical components of any fluid control system. A liquid or gas flow inside a pipeline may be halted or regulated easily with its assistance. Bolting between two pipe flanges, high-strength designs approach the valve ends to provide a dependable and secure seal from the inside out.
Because of their outstanding mechanical capabilities, corrosion resistance, and sturdy features, most of these valves are made of brass, mostly copper and zinc alloy. Isolation valves made of flanged brass provide flexibility and reliability for most of the criteria applicable to industrial and residential applications.
Main Parts:
The major parts that comprise a flanged brass isolation valve include:
- Body: The main housing, typically brass, holds the internals.
- Bonnet: The cap that gives access to the internals.
- Stem: The rod that moves the valve mechanism by the handle or actuator.
- Disk: The moveable piece that can open or close the valve depending on the isolated valve type.
- Seat: The sealing surface the disk/gate/ball seals against to shut off flow.
- Flanges: These are flat, projecting rims and can bolster the valve onto the pipeline.
Why Is Brass Used for The Production of Flanged Isolation Valves?
It is associated with maintaining efficacy in various environments, including water, oxygen, and specific compounds, and possesses a high level of corrosion resistance. In addition, it is ductile and possesses an exceptional capacity to conduct heat, rendering it advantageous for applications that experience temperature changes.
Additionally, brass is capable of being machined and cast into a variety of valves. Also, this material can resist high pressure and mechanical stress, thus ensuring the valves have a long service life.
Design and Appearance of Flanged Brass Valve

The appearance of the flanged brass isolation valve is distinct in its function. The smooth, luminous finish on the valve’s body reveals a characteristic golden polish that signals the brass content. The machining of the flanged ends allows seamless closure and precise mating to pipeline flanges. Actuators or handles are fabricated in rigid plastic or metal designed to rotate quickly.
The design is robust and reliable, and all the components provide maximum efficiency to achieve the best possible life. Brass valves have an elegant and, at the same time, helpful appearance due to their color and brightness.
Surface Treatment
Surface treatments are indispensable for improving the performance and extending the lifespan of flanged brass isolation valves. Polishing, plating, and coating are the most frequently employed procedures. Polishing is used to eliminate surface imperfections.
They may possess clear and sleek finishes. They can be further plated with nickel or chromium to enhance their appearance and corrosion resistance. Protective layers like epoxy or particle coating are implemented in extreme environmental conditions. These surface treatments guarantee valves maintain their functionality and integrity for an extended period, even in the most demanding applications.
