Ball Valves
Centro offers a reliable selection of ball valves or flow control valves designed for smooth operation and long-lasting performance in a wide range of applications. These quarter-turn valves provide tight shutoff capabilities, making them ideal for use in fluid systems requiring low torque and minimal leakage.
Ball Valves are available in a variety of materials including brass, stainless steel, and PVC, our solutions support industrial needs. Whether you're managing water, oil, gas, or chemical flow, Centro's valve options ensure durability and precise control.
With configurations ranging from full port to reduced port and options for 1-piece, 2-piece, and 3-piece designs, we provide flexibility for everything from general plumbing to high-pressure industrial systems.
Explore our complete range of ball valves to find the right fit for your application or contact our experts for personalized guidance.
Valve Accessories
Valve accessories are additional components that enhance the functionality and performance of valves in fluid control systems. These accessories are designed to provide other features, improve safety, or simplify maintenance of the valves. Valve accessories enhance the reliability, efficiency, and safety of valve operations, making them essential for various industries such as oil and gas, chemical processing, water treatment, and power generation.
