The ball valve is one of the most commonly used valves in all types of systems and applications. It is easy to use, durable, and it is designed to be practical to control the flow of media through a specific location in the system.
The Operation of the Ball Valve
All ball valves work the same way. They are a quarter-turn valve, which means they can be fully open or fully closed with just a 90-degree turn of the exterior lever. In addition, the position of the lever makes it easy to see if the system is on or off (flowing or closed) with just a glance at the position of the lever. When the lever is parallel with the incoming and outgoing port, the valve is open and flowing. If the lever is perpendicular to the line, the valve is closed.
The interior of the valve is a hollow ball with a hole drilled through the middle. When the valve is open, the hole lines up with the inlet and outlet port to allow free flow through the valve. When closed, the ball rotates to block the ports, fitting snugly into the valve seat for a complete seal.
The Benefits of Polypropylene
Ball valves can be made of many different types of materials. There are bronze, stainless steel, and brass valves, and there are also those made of exotic alloys and plastics.
One of the most cost-effective and practical solutions is the polypropylene ball valve. Resistant to corrosion, heat, and a variety of different types of media, the polypropylene ball valve is ideal for both high pressure and high-temperature types of systems.
In addition to performance, a polypropylene ball valve is manufactured through injection molding processes. This means no seams or joints in the valve, reducing the risk of any type of failure of the valve at these points as is common with valves made by other production methods.
