Single-piece ball valves are durable and simple but limited in size. Two-piece valves allow easier maintenance and cover more sizes, while three-piece valves offer the easiest maintenance with modular parts but are more complex and expensive. Each type balances durability, ease of service, and application needs.
Features
Quarter-Turn Operation: Ball valves operate with a 90-degree turn of the handle, providing quick and straightforward on/off control of fluid flow.
Tight Sealing: They use a spherical ball with a hole in the center and resilient seals, typically made of PTFE, to ensure a tight, leak-proof seal when closed.
Low Pressure Drop: The straight-through design of the ball valve minimizes resistance to flow, resulting in a lower pressure drop compared to other valve types.
Durability: Made from robust materials like stainless steel or brass, ball valves are designed to withstand high pressures and temperatures, offering long service life.
Versatility: They are suitable for a wide range of fluids and applications, including water, oil, gas, and chemicals, with various configurations and sizes available to meet different operational needs.
