PVC ball valves are valves that open when a handle or lever attached to the ball inside the valve is turned. They can be made of metal or plastic and usually have a ceramic center. Chrome-plated varieties are also available nowadays. The chrome-plated ones are more durable than the other ones. It is generally used for shutoff applications. They are durable and achieve the perfect shutoff even after years of disuse.
The variety discussed above is basically a two way valve. Three-way, T-shaped left, and the L-shaped ball right varieties are also available. These devices have a port, which is used for allowing smooth flow of the fluid. Smooth flow of the liquid occurs only when the port is in line with both ends of the device. For this to happen, the ball should have a hole in it. For its adaptability and flexibility to withstand pressures and high temperatures it is widely used in industries.
Types of ball valves
These fixtures come in different styles. Welded, three piece body, single body, top entry, and split body are the models generally used. The following types of ball valves are available in the market:
- Trunnion ball valve: This type is generally used for bigger valves that have to withstand very high pressure. In this type of ball valve, the ball is anchored at the top and at the bottom.
- Reduced port ball: In this type the flow area is less than the pipe size of the valve but the flow remains constant. They generally have one ball and are comparatively cheap.
- Full port ball: This is just the opposite of the reduced port ball. In this type the ball’s hole size is similar to the size of the pipeline. The large size of the valve allows less loss of friction.
- V port ball: As suggested in the name, this type either has a V-shaped ball or seat.
The PVC balls and accessories are cheap and very easy to install. They are easy to repair and can be operated by actuators or manually. Compared to the other fittings this type of fixtures does not pose any risk of fire during installation. PVC fittings are safe as they do not emit toxic fumes that may cause fire.
So when you need ball valves, opt for the PVC ones without hesitating.
