The ball valve is the most common and widely used type of fluid or gas interception device.
Its operation is based on the 90° rotation of a spherical shutter equipped with a cylindrical cavity coaxial to the flow.
The ball valve can be opened or closed, thus allowing flow reduction.
• Monoblock or 3-Piece BALL VALVE: This valve is available in both monoblock and three-piece screwed or flanged versions. It is suitable for medium-low pressures, with materials such as brass for lower pressures and carbon steel or stainless steel for higher pressures.
• Wafer BALL VALVE: This type of valve is designed to be mounted between flanges, offering a compact and easy-to-install solution. It can be made in a variety of materials, including stainless steel and synthetic materials such as PVC, PP, and PVDF.
• Split Body BALL VALVE: With the body divided into two parts, this valve offers ease of maintenance and greater flexibility. It is commonly made of carbon steel or stainless steel to ensure strength and durability.
• Trunnion Ball Valve: Characterized by a robust and stable design, this valve offers reliable and long-lasting performance.

For medium-low pressures machined brass ball valves are used; for higher pressures, carbon steel or stainless steel is preferred.
Due to their characteristics, ball valves are well-suited for production through forging, allowing them to be made from virtually any metal material.
Ball valves made from synthetic materials, especially PVC, but also PP and PVDF, are commonly used for applications involving non-corrosive hot fluids.
The obturator is usually made from the same material as the body (stainless steel is often used with bodies made from less noble metals) and has a highly polished surface finish to ensure good contact with the sealing seat.
This seat consists of two shaped rings, almost always made of PTFE (Teflon); the stem is made from the same material as the ball or the body, and it also seals with appropriately shaped PTFE rings.
The operating lever is typically made of cast or stamped aluminum for smaller valves and corrosion-protected steel for larger valves. For valves over DN 100, a worm gear reducer is used to reduce the effort required for opening and closing.
At MAGVALVES we are committed to offering a wide range of ball valves designed to ensure reliability and durability. Our customized solutions are designed to meet the specific needs of each application, always guaranteeing the highest quality and fast delivery service.
