Types of Flanged Ball Valve

The flanged ball valves produced by our company mainly include the following types:

 
 

Api Flanged Ball Valve

API flanged ball valve is a ball valve designed and manufactured according to the standards set by the American Petroleum Institute (API), specifically with flanged end connections, meaning it attaches to pipes using flanges, and is typically used in oil and gas pipelines due to its ability to handle high pressure and temperature conditions while providing a tight seal for flow control.

 
 
 

Wcb Flanged Ball Valve

WCB flanged ball valve refers to a ball valve where the body is made from "WCB" material (Weldable Cast Steel, Grade B) and has flanged connections on either end, meaning it is designed to be attached to a pipe system using flanges instead of threads.

 
 
 

Stainless Steel Flanged Ball Valve

A stainless steel flanged ball valve is a valve that controls the flow of fluids using a floating ball and flanged ends. The valve can be manually operated with a handle or automatically operated with a motor.

Installation Steps of Flange Ball Valve

● The front and rear pipes should be coaxial. The sealing tops of the two flanges should be parallel. The pipeline should be able to bear the weight of the valve. If it is impossible, the channel must be equipped with proper support.

 

● To remove oil, welding slag, and all other impurities present in the pipeline, we should run an expulsion procedure of the channels.

 

● The flange ball valve should be fully intact. For this, we can check the sign of the flange ball valve and make sure. We should also make sure that the valve is working correctly. We can check it by opening and closing the valve several times.

 

● Eliminate the protective parts of the flange ball valve at both ends of the connecting flanges.

 

● Check the valve hole to eliminate and clean any possible filth. Even small foreign particles between the valve seat and the ball may harm the sealing surface of the valve seat.

Storage Precautions for Flange Ball Valves
 

The valves must be kept in a safe environment. Dust and humidity may damage the valves. The area should be well-ventilated.

 

Before putting the valve in, you must make sure that the end protectors are in place. If not, dry pollutants like dust, sand, and grit can scratch the metal surfaces and parts of the seats, which can cause leaks when the car is being serviced.

 

One should keep the valve at a temperature more significant than the dew point temperature at the storage location. It will help to prevent the increase of water droplets on the valve sheet.

 

It is against the law to leave the valve on the floor. We can put the valve on a wooden pallet so that it is just above the floor. We must always take care not to damage any parts of the adaptor, gear unit, or actuator that protrude during storage.

 

Non-compatible grease or any other material inside the valve is prohibited. It may malfunction the valve.

 

A nontoxic coating of “Manganese Phosphate” was used for the steel valves. It slows down the creation of rust during storage. With their natural finish, you can use stainless steel valves also.

FAQ

Q: What is the difference between a threaded and a flanged valve?

A: The difference in cost between the two connection types is due to the multiple parts and various structures of flanges. However, despite the cost-savings associated with threaded valve connections, they offer less operational flexibility and are primarily only useful in low-pressure piping systems.

Q: How do I choose a ball valve?

A: It's crucial to select a ball valve with a maximum pressure rating that surpasses the system's requirements. Flow requirements: when assessing a system's flow needs, factors like fluid flow rate, pressure drop, and leakage must be carefully considered.

Q: How do I know what size ball valve I need?

A: You can use your current fittings to select the right ball valve size. To do this, you'll need the following measurement: External measurement of the male thread on the fittings: Similarly, if the external diameter of the male thread is close to a particular size, you'll need a ball valve of the same size.

Q: What is the life expectancy of a ball valve?

A: Many ball valve manufacturers provide an estimate of expected ball valve lifespan (usually eight to 10 years), and proper maintenance can certainly extend this range. However, ball valve lifespan can be influenced by a variety of other factors.

Q: Should ball valve be fully open?

A: A ball valve does not always need to be fully open, but whether it should be fully open or not depends on the application and the design of the valve. Ball valves are typically designed for full on/off control, meaning they function best when they are either fully open or fully closed.

Q: How to stop a ball valve from dripping?

A: To fix a ball valve leaking at the handle, first turn off the water supply and relieve pressure from the valve. Then, tighten the packing nut or gland nut located just below the handle; if this doesn't stop the leak, you may need to replace the packing material or O-ring inside the nut.
