What Is An Aluminum Bronze Check Valve?
Jun 20, 2024
An aluminum bronze check valve is a type of valve made from aluminum bronze, a strong and corrosion-resistant alloy of copper, aluminum, and sometimes other metals. This type of valve is commonly used in applications where high pressure, high temperature, or corrosive fluids are present. Learn more about aluminum bronze check valves here.
Aluminum Bronze check valves offer many advantages, which make it a worthwhile choice when considering applications requiring low maintenance with reasonable costs associated with them.
They are designed to allow fluid to flow in only one direction, preventing backflow and potential damage to equipment or the environment. Let’s take a comprehensive look at the valve.
What is Aluminum Bronze Check Valve?
An aluminum bronze check valve is a type of valve that is used to control the flow of fluids in a pipeline. It is made from aluminum bronze, an alloy of copper and aluminum that is highly resistant to corrosion and erosion. The valve is designed to allow fluid to flow in only one direction, preventing backflow and protecting equipment and pipelines from damage. Aluminum bronze check valves are commonly used in applications where high pressure, high temperature, or corrosive fluids are present, such as in the chemical, petrochemical, and marine industries.
Types of Aluminum Bronze Check Valves
Aluminum bronze is a copper-based alloy composed of iron and nickel; by adding aluminum, their strength increases dramatically.
1. Flanged
Flanged aluminum bronze check valves are commonly found in pipelines and other fluid handling systems to regulate fluid flow. Available in numerous sizes and designs, these check valves provide effective fluid control solutions.
This type of valve is a spring-assisted center-guided design featuring a disc that moves along the centerline of the valve seat for reliable shutoff as well as flow regulation or throttling capabilities.
2. Threaded
Threaded aluminum bronze check valves can be found across industries but are especially prevalent in petrochemical and steam applications. Their rugged construction allows them to withstand harsh environments as well as high-pressure environments found within these applications.
They’re also ideal for gas and oil production applications with high temperatures and lengthy opening and closing cycles, such as gas extraction or refining.
3. Threaded Body
Threaded Body Aluminum Bronze Check Valves provide an economical and effective solution to backflow problems, made of superior-grade materials and suitable for commercial construction, fire protection, HVAC, irrigation, mining, water & waste treatment systems as well as oil & gas generation applications.
4. Threaded Stem
Threaded stem aluminum bronze check valves have an array of uses in water lines, oil, and gas pipelines, petroleum refineries, food processing facilities, power plants, seawater pollution control, and wastewater management applications. Their compact design makes them cost-effective solutions.
This valve features a bronze body and trim, along with a flanged connection and bolted cap for use with pump discharge piping applications, where it acts as a spring-loaded silent check valve, shutoff valve, and balancing valve.
Applications of aluminum bronze check valve
Aluminum bronze check valves are commonly used in various industries for their excellent corrosion resistance, high strength, and durability. Some of the typical applications of aluminum bronze check valves are:
Chemical processing
Marine applications
Mining industry
Oil and gas industry
Power generation
Water treatment
Working principles of aluminum bronze check valve
Aluminum bronze check valves are designed to allow fluid to flow in only one direction, preventing backflow and protecting downstream equipment.
The valve body is typically made of aluminum bronze, which is known for its high strength and resistance to corrosion.
The valve has a hinged disc or ball that is held in place by a spring. When the fluid flows in the desired direction, the disc or ball is pushed open, allowing the fluid to pass through.
If the fluid tries to flow in the opposite direction, the disc or ball is forced closed by the pressure of the fluid, preventing backflow.
Aluminum bronze check valves can be designed to work in a variety of flow conditions, including low and high pressure, low and high temperature, and low and high flow rates.
Some aluminum bronze check valves are equipped with a lever or handle that can be used to manually open or close the valve for maintenance or testing purposes.
Advantages and Features of Aluminum Bronze Check Valves
Aluminum bronze check valves are highly valued alloys due to their exceptional strength, corrosion resistance, and toughness. Tarnish-resistant and boasting low rates of atmospheric corrosion; low rates of high-temperature oxidation; as well as being inert with sulfurous compounds from combustion products or any sulfur-containing gases present; these qualities make Aluminium bronze valves perfect choices for desalination projects as well as any situation requiring a long-wearing hard-wearing valve.
Durability
Aluminum bronze check valves stand up well under high temperatures and pressures, making them the ideal solution for applications that may be susceptible to corrosion and wear.
These valves also boast excellent flow regulation and shutoff capabilities thanks to their moving valve disc that alters the valve seat port.
Corrosion Resistance
Aluminum bronze valves offer excellent corrosion resistance in saltwater environments and biofouling protection, which makes them especially advantageous for offshore platforms.
These pumps can handle harsh chemicals and acids without malfunctioning, making them an excellent choice for use in oil & natural gas industries, chemical plants, and marine facilities.
Additionally, they can withstand high pressures and temperatures without tearing or cracking, which makes them useful in cryogenic conditions – an invaluable asset in certain applications.
Lifespan
Aluminum bronze check valves boast an extended lifespan compared to other forms of valves, are resistant to corrosion, and can withstand various temperatures and pressure levels without succumbing to wear and tear. Furthermore, these durable valves can easily be maintained. Aluminum bronze valves can be found used across many industrial applications and come in various sizes, styles, and pressure categories for convenient use.
Cost
Aluminum bronze check valves are suitable for many different applications, from industrial to marine use. Their advantages include superior strength and corrosion resistance.
These valves are designed to allow one-way flow and prevent reverse flow in piping systems and come in various body and bonnet materials with several trim options available.
These valves also include features to make maintenance simpler, such as torsion springs that close the valve before flow reversal and downstream stop shafts that stabilize discs under high pressures.
