$ 22.41
Item Number: SX3100
- Universal Multi-Link Modular Versatility: Engineered to adapt seamlessly into standard dental delivery head water matrices. Available in scalable Single-Link (1-Way), Double-Link (2-Way), and Triple-Link (3-Way) joint blocks. This multi-port flexibility allows repair technicians to replace an individual handpiece water circuit or upgrade the entire main cuspidor/scaler water supply grid simultaneously. Precision-Calibrated Technical Footprint: Each valve housing block adheres strictly to standardized mechanical spacing laws (with the single block dimensioned exactly at a compact 46.5mm in length, 29mm in chassis height, and 19mm in structural thickness, scaling up linearly for multi-link variants as certified. This ensures direct drop-in alignment inside tight handpiece holder bays and internal junction boxes without structural modifications. High-Grip Leak-Proof Barbed Connectors: Outfitted with specialized multi-tiered, tapered barbed hose nipples protruding from the top and lateral bulkheads. The optimized serrated ridge angle locks onto standard inner-diameter dental PU/PVC tubes tightly, resisting high pneumatic pressure spikes up to $0.6\text{MPa}$ without requiring ugly external hose clamps. Solid Brass Anti-Calcification Core: The main fluid chamber is CNC-machined from high-purity brass. This metallurgical selection possesses exceptional resistance against calcium buildup, biofilm deposition, and mineral scaling from hard municipal water lines, ensuring the internal gating pathways stay open and unobstructed over years of continuous clinical activation loops. Hermetic Diaphragm Pressure Balancing: Utilizing a high-tensile, chemical-resistant internal rubber diaphragm matrix secured by reinforced side hex-screws. This dynamic seal isolating mechanism prevents crossover leakage between the pneumatic control air and the driven water line, assuring zero-drip cutoffs the millisecond the foot control pedal is released. Optimized Weighted Stability: Weighing in at exactly 72g for the single-joint module (as officially cataloged in the technical weight banner, the solid mass profile acts as a natural dampener against pipeline water hammer vibrations, protecting delicate ambient plastic fittings from stress fractures.

Field Technician Installation & Maintenance Guidelines: System Depressurization & Disassembly: Shut off the dental chair’s main master switch, and completely vent the air compressor storage line and water regulator grid to zero pressure. Open the delivery unit’s plastic outer housing. Identify the leaking water valve block, map the incoming and outgoing tube lines clearly, and disconnect them carefully using a hose puller. Modular Mounting & Hose Fitting: Choose the appropriate replacement valve module (matching the single, double, or triple configuration required by your handpiece lines; refer to the body outline. Secure the valve block into its designated mounting tray slot inside the delivery head. Dip the ends of your 4 x 2.5mm or 6x 4mm poly-tubes into hot water for 3 seconds to soften them slightly, then push them firmly over the barbed tapered nipples until they seat completely flush against the brass hex base nuts. Pressure Calibration & Leak Testing: Turn the master air and water supply lines back on. Depress the foot control pedal repeatedly to flush air locks out of the lines. Check the side seams and the hex-screw perimeter plates for any signs of weeping or moisture. Adjust your master water pressure regulator until you achieve a clean, smooth aerosol mist through the handpiece lines. Wipe the valve block down with a clean, dry cloth before sealing the delivery head housing.
