What is Manifold Valve?
Manifold valves are essential components in industrial fluid control systems, widely used in sectors such as oil & gas, petrochemicals, and process engineering. These compact units integrate multiple valves into a single block or assembly, allowing for more streamlined and efficient regulation, isolation, and distribution of fluids or gases.
A manifold valve typically connects two or more valves within a hydraulic or instrumentation system. By combining various valve types, such as needle, bleed, ball, and vent valves, into one body, manifold valves help reduce the need for multiple individual connections, minimizing potential leak points and saving valuable space.
Each valve within the manifold has a dedicated inlet or outlet port that connects to a pipe or line, while sharing a common valve chamber. This integrated design not only simplifies installation but also cuts down on maintenance time and cost.
Manifold valves are particularly valued for their ability to handle high-pressure applications while maintaining precise control. Their compact design, combined with functional versatility, makes them a reliable choice for optimizing system performance and ensuring safety in complex fluid systems.
Types of Manifold Valves manufactured by Arrotop
Manifold valves come in various configurations, each designed to meet specific operational needs in fluid and pressure control systems.
