Dental Oilless Air Compressor Solenoid Valve & Check Valve Kit: AC 220V IP65 Unloader Valve with Brass One-Way Valve Replacement
$ 13.41
Item Number: SX3100
- CE Certified Chenhao Premium Solenoid Core: Driven by an authentic, industrial-grade Chenhao direct-acting pilot solenoid actuator (prominently labeled on the primary chassis. Fully compliant with European CE standard protocols, this valve operates smoothly under consistent AC 220V grids at both 50Hz and 60Hz frequencies with a low power draw of just 6.0VA / 4.5VA. IP65 Rated Moisture-Proof MPM Junction Block: The solenoid head is outfitted with a transparent, heavy-duty MPM terminal connector block secured by a central steel locking bolt. This enclosure provides complete IP65 water and dust ingress protection, preventing electrical tracking, short circuits, or internal coil corrosion in damp dental utility basements or tight acoustic cabinet spaces. Heavy-Duty Forged Brass One-Way Check Valve: Features a premium, heavy-wall forged brass non-return valve block with deep structural reinforcement ribs. Engineered with a high-tension internal stainless steel spring and a medical-grade fluoropolymer sealing disc, it allows compressed clean air to pass into the main storage tank while completely blocking backward air leaks when the pump cycles off. Low Temperature-Rise Continuous Duty Cycle: Built with optimized structural copper windings that limit core temperature rise to ≤ 35°C even under 100% ED (Continuous Duty) operations. This ensures steady pneumatic control without thermal breakdown during peak clinic working hours. 3-Piece Universal Tube Adapter Array: Comes packaged with three precision-machined pneumatic plumbing joints to handle diverse flexible or rigid air line layouts across different chair brands: Straight Metallic Compression Joint: Delivers an airtight double-ferrule mechanical grip for standard nylon or copper manifold pipe sections. Pneumatic Blue Lock-Collar Push-In Fitting: Allows instant, tool-free push-to-connect sealing for flexible polyurethane (8mm or 10mm) pilot lines. 90°C Right-Angle Elbow Compression Joint: Provides smooth path routing in cramped compressor layouts, keeping lines from bending or collapsing. Technical Specifications Matrix Product Classification: Medical Air Compressor Utility Overhaul Kits / Solenoid & Non-Return Check Valve Combos Chassis Metallurgy Core: Forged High-Density Structural Brass Body CE Certified Polymer Encapsulated Actuators Electrical Operational Parameters: Rated Coaxial Voltage: AC 220V (Dual Frequency Adaptable: 50Hz / 60Hz) Apparent Continuous Power Draw: 6.0VA / 4.5VA Maximum Rated Continuous Current Profile: 29mA Temperature Rise Ceiling Parameter: Up to 35°C under full 100% ED Cycle Loading Ingress Protection Level: Fully Waterproof IP65 Rated Shell Fitting Mechanical Pressure Tolerances: Optimized for universal dental clean-air networks spanning up to 1.0MPa (10Bar) Primary Target Operational Workflows: Rebuilding Multi-Chair Oil-Free Air Stations, Resolving Air Tank Leakbacks, Replacing Burned-Out Compressor Solenoids, Overhauling Central Clinical Plant Infrastructure, Reducing Motor Starting Inrush Current ? Field Service Engineer Overhaul & Installation Protocol: Pneumatic & Electrical Safety Lockout: Shut off the air compressor’s main breaker switch and pull its power cord from the wall. Slowly open the main tank drain valve to bleed off all stored air pressure until the system gauge reads exactly 0psi. Old Component Stripdown & Thread Preparation: Unthread the old wire leads from the control pressure switch block. Use a crescent wrench to remove the failed solenoid valve and the worn brass check valve from the tank manifold assembly. Use a wire brush to clean any old pipe dope or worn PTFE tape from the female receiving ports. Double Valve Integration & Connection Check: Take the new brass non-return check valve and thread it tightly onto the tank intake port using fresh thread sealant, making sure the directional flow arrow points toward the tank interior. Next, install the new Chenhao solenoid valve body into the unloader loop, choosing the right tube adapters from the included compression or push-in kit. Securely attach your pilot lines, route the power leads back through the pressure switch housing, close the drain tap, and power the compressor back up to confirm crisp, automatic air bleeding with zero micro-leaks.
