Brass ball valves refer to ball valves made of brass material, namely the valve body is brass. Brass is the alloy that is made up of copper and zinc. It is called normal brass if it is made up of copper and zinc only. However, it is called special brass if it is made of multiply alloys, which is made up of more than two elements.

Brass ball valve is evolved from plug. The opening and closing body of brass ball valve is a ball and it realizes opening and closing when the ball rotates 90˚around the axis of stem. According to supporting method of the ball, brass ball valve can be divided into floating ball valve and fixed ball valve. It's mainly used for cutting off, distributing and changing the flow direction of the media. The open ball valve designed to V shape also has good flow regulation function.

Brass Ball Valves Advantages

The main advantages of brass ball valves as: tight structure; reliable sealing; simple structure; easy maintenance; not easy to get corroded by the media when the sealing surface and ball surface is under closed state, and easy to operate and maintain, applicable for normal media like water, solvent, acid and natural gas etc., and applicable for the media under hostile environment, like oxygen, hydrogen peroxide, methane and ethylene etc., and widely used in all kinds of industries. The valve body of ball vale can be complete or combined.

There are such materials as cast iron, brass, WCB, stainless steel, alloy steel, PVC, ABS that are suitable for making ball valves. Among them, brass ball valve is normally used for household water pipe or low pressure and small size valve used in gas pipe. The fabrication is simple, and price is low, brass is more expensive than steel, while cheaper than stainless steel. By the comparing brass vs bronze vs stainless steel ball valves and others, customers can find out the right products they want.

Brass vs Bronze Ball Valves

Brass ball valves and bronze ball valves are differnent from each other in the following aspects:

Different elements

Brass is the alloy consisting with copper and zinc. It is called normal brass if it consists with copper and zinc only. And it is called special brass if it consists with multiple alloys constituting by more than two elements.

Bronze originally means copper-tin alloy, and then all the copper alloys except brass and white brass are called bronze. And usually put the first main adding element before bronze.

Different application

Brass has strong wear-resistance, and is often used to make valves, water pipes, connecting pipes for A/Cs and radiators etc.. brass valve can be forged and used under high pressure situation.

Bronze has low melting point, large hardness, malleable, wear-resistance, corrosion-resistance, bright color etc., often used to make tools, mechanic accessories, bearing, gear etc.. bronze valve can be casted and cannot be used under high pressure situation.

Different performance

Bronze has good wear-resistance, brass is less wear-resistant than bronze. While the tenacity of brass is better than bronze, so brass valve is easier to fabricate.

Brass is less corrosion-resistant than bronze, has poor service life compared with bronze valve.

Different price

Normally the brass is cheaper than bronze.

Brass vs Stainless Steel Ball Valve

Brass and stainless steel ball valves are commonly used in plumbing and industrial applications due to their durability and corrosion resistance. Here are some differences about brass vs stainless steel valves:

Corrosion Resistance: Stainless steel has a higher resistance to corrosion than brass, making it more suitable for harsh environments where exposure to moisture, chemicals, or saltwater is a concern.

Strength: Stainless steel is stronger than brass, which makes it more durable and resistant to wear and tear.

Temperature Resistance: Stainless steel ball valves can handle a wider range of temperatures than brass valves, making them suitable for high-temperature applications.

Price: Brass ball valves are generally less expensive than stainless steel ball valves, making them a more economical option for low-pressure and low-temperature applications.

Applications: Brass ball valves are commonly used in plumbing, heating, and air conditioning systems, while stainless steel ball valves are preferred in chemical, petrochemical, and oil and gas industries, where exposure to harsh chemicals and high temperatures is a concern.
