An Internal Hexagonal Plug controls hydraulic flow by securely sealing unused or service ports within a hydraulic manifold system. This component prevents hydraulic fluid from escaping and ensures that pressure remains stable throughout the operating cycle. By closing open passages, the plug supports accurate direction of fluid to active circuits and avoids unwanted pressure drops. Controlled sealing helps maintain balanced hydraulic performance during operation.Attributes:• Provides a secure seal for open hydraulic manifold ports to prevent fluid escape.• Maintains stable hydraulic pressure within the valve manifold assembly.• Supports accurate flow routing by closing inactive passages.• Seal material is fluorocarbon rubber used for seals requiring high resistance to heat and chemicals.Applications: An Internal Hexagonal Plug is installed within hydraulic valve manifold assemblies where unused or service ports require sealing. It maintains internal pressure balance and prevents hydraulic fluid leakage, supporting stable and controlled system performance.
