Product Description Product DescriptionNAl-LOK brand was established in Shanghai in 2000, we focus on the production, research and development, salesof instrumentation valves, fittings, hose & tubing.Product OverviewThe High Pressure UDB Diaphragm Valve is designed for precise flow control in high-pressure applications, including chemical processing, pharmaceuticals, and water treatment. Its unique diaphragm design ensures leak-proof operation, corrosion resistance, and minimal maintenance.Installation InstructionsPositioning: Install in the desired flow direction (marked on the valve body). Ensure proper alignment with pipeline flanges or threaded connections.Mounting: Use appropriate gaskets and fasteners to prevent leaks. Tighten bolts evenly in a crisscross pattern.Pressure Test: Before full operation, conduct a low-pressure test to verify sealing integrityOperating GuidelinesOpening/Closing:Handwheel-operated models: Turn clockwise to close, counterclockwise to open.Automated models: Follow control system instructions.Pressure & Temperature Limits: Do not exceed the rated PN (pressure nominal) or temperature range specified in the datasheet.Flow Control: Adjust the diaphragm gradually to avoid sudden pressure surges.Maintenance & SafetyDiaphragm Inspection: Check for wear, cracks, or deformation periodically. Replace if damaged.Seal Replacement: Use only OEM-approved gaskets and diaphragms.Cleaning: Flush with compatible solvents to remove buildup (avoid abrasive cleaners).Safety Warning: Never disassemble under pressure. Isolate and depressurize the valve before servicing.TroubleshootingLeakage: Tighten connections or replace the diaphragm/gasket.Stiff Operation: Lubricate the stem (if applicable) or check for diaphragm misalignment.Reduced Flow: Inspect for obstructions or diaphragm damage.
