Thread Ball Valve Collection

Threaded ball valves feature internal and external threads. These threads facilitate the connection between the inlet and the outlet of a valve. However, threads on ball valves can also be damaged by fluids.  In order to avoid damage, check the manufacturer's history and certifications. Many threaded ball valve manufacturers have minimum order quantities. Make sure to check these guidelines before ordering.  The cost of threaded ball valves varies based on quality, grade, and quantity. Standard threaded ball valves are more affordable than custom-made ones. When comparing threaded ball valve prices, remember to take your specific project requirements into account.

What Are Threaded Ball Valves?

A threaded ball valve is a type of valve that comes with a threaded connection. These valves are easy to install and fairly inexpensive. They're best for smaller applications because they have smaller diameters.

 When used in larger applications, they are more prone to leaks through the threads. To prevent leaks and protect against galling, you can use pipe tape to seal the threads. The proper sealant will prevent any metal-to-metal contact and will also prevent galling.

These valves are available in three common designs, i.e., male x male, female x female, and male x female. Before installing a threaded ball valve, you should always clean its ports and seat to remove any foreign particles. Clean the threads as well. If any metal shavings are present, you can use a high-quality pipe thread sealing compound or PTFE thread sealing tape. This step will ensure that your valve is leak-proof. 

A threaded ball valve provides a tight connection and is the most common type of connection used in ball valves. It offers a tight seal between the valve and the pipe. Most of the ball valves incorporate threaded connections.

What Thread is on a Ball Valve?

A threaded valve connection provides a tight, streamlined seal. A female threaded valve connection fits over a male threaded pipe. Here are the two types of threads used on ball valves. 

  • Straight Thread

The threads on a ball valve can be either straight or tapered, and they differ in their diameter. Straight threads usually require an O-ring for sealing, while tapered threads do not. Pipe tape can be used between the female and male threads to provide lubrication and sealing and to prevent metal-to-metal contact. Threads are classified according to their dimensions in international standards. When choosing a threaded ball valve, check its rating. This specification is important because a threaded valve cannot absorb gaps or distortion in the pipe. Moreover, a straight-threaded valve may develop leaks if the pipe has been dismantled. 

  • Taper Thread

Another type of thread used in ball valves is taper thread. This type of thread connection tapers towards the end. The best thing about this thread connection is that it doesn't require an O-ring seal. However, you will still need sealant and pipe tape to get the best seal. This way, there will be no leakage when you use the ball valve. When selecting threads for a ball valve, it's best to use a caliper to determine the diameter of each. Some tapered valves use pipe tape between the male and female threads to serve as lubricant and sealing and help prevent metal-to-metal contact.
