This kit plays a critical role in regulating injection oil temperature, preventing moisture condensation, and stabilizing compressor thermal performance under fluctuating load conditions. It is widely utilized in heavy-duty industrial compressed air systems across the manufacturing, automotive, electronics, and power generation sectors. Atlas Copco 60°C Thermostatic Valve Service Kit 2901044700 (1) Technical Specifications The following technical data table outlines the official physical dimensions and operational parameters for the 2901044700 thermostatic valve service kit. Parameter Specification Part Number 2901044700 (2901-0447-00) Included Core Components 1202586902 Thermostatic Element, 1622707002 Seal Kit, Heavy-duty Return Spring, High-temperature Gaskets Dimensions (W×H×L) 14.0 cm × 1.0 cm × 29.0 cm Weight 0.274 kg Initial Opening Temperature 60°C Full Open Temperature Approximately 75°C Main Materials High-strength corrosion-resistant brass alloy, Fluoroelastomer (Viton) / EPDM, Stainless steel Recommended Replacement Interval 4,000–8,000 operating hours (Subject to site ambient temperature and duty cycle) Atlas Copco 60°C Thermostatic Valve Service Kit 2901044700 (2) Key Components & Sub-Assembly The 2901044700 maintenance kit bundles all necessary OEM components required to complete a full overhaul of the oil temperature control valve assembly during major service intervals: 1202586902 Thermostatic Valve Element: A wax-based thermal actuator that expands and contracts precisely according to the actual oil temperature, calibrated to initiate opening at exactly 60°C. 1622707002 Seal Kit: Comprises premium fluororubber O-rings and high-temperature gaskets designed to withstand aggressive synthetic lubricants and prevent external oil leakage. Calibrated Return Spring: Provides the precise mechanical resistance required to push the valve element back to the bypass position as the oil cools down. Atlas Copco 60°C Thermostatic Valve Service Kit 2901044700 Working Principle Positioned strategically between the oil separator tank and the oil cooler, the thermostatic valve manages oil routing through three distinct operational phases to maximize system efficiency: Cold Start Phase (<60°C): The 1202586902 element remains fully closed, forcing the lubricating oil to bypass the oil cooler and return directly to the compressor element (airend). This rapid warm-up prevents atmospheric moisture from condensing inside the oil circuit. Modulation Phase (60°C–75°C): As the oil temperature reaches 60°C, the internal wax core expands, overcoming spring tension. The valve partially opens, mixing cold oil from the cooler with hot oil from the bypass line to maintain a stable, optimal injection temperature. Full Cooling Phase (>75°C): At high loads or elevated ambient temperatures, the valve opens completely, closing the bypass circuit entirely. 100% of the oil flow is directed through the oil cooler to safeguard the airend from overheating. Atlas Copco 60°C Thermostatic Valve Service Kit 2901044700 (3) Signs of a Failing Thermostatic Valve Thermostatic valve elements wear out over time due to thermal fatigue or varnish build-up. Failure to replace the kit can result in two severe operational symptoms: Stuck Closed (Overheating Faults): If the valve fails to open, oil cannot reach the cooler. The compressor will rapidly overheat, exceeding 100°C, leading to frequent high-temperature trip shutdowns and unscheduled production downtime. Stuck Open (Oil Emulsification): If the valve remains permanently open, the oil undergoes over-cooling during startup. The system fails to reach optimum operating temperature, causing water vapor to condense in the oil tank, which degrades lubricant properties and accelerates bearing wear. Atlas Copco Thermostat Element 1622707002 Installation & Maintenance Best Practices To ensure a successful overhaul using the 2901044700 service kit, maintenance teams should follow these professional engineering guidelines: Complete Depressurization: Always shut down the compressor, isolate the electrical mains, and verify that the internal pressure gauge of the air/oil vessel reads 0 bar before loosening the valve housing. Thorough Cavity Cleaning: Remove any residual varnish, sludge, or old gasket material from the internal housing walls before inserting the new 1202586902 thermal element. O-Ring Lubrication: Apply a thin film of fresh compressor lubricant to the new O-rings from the 1622707002 kit to prevent twisting or pinching during assembly. Spring Tension Control: The valve cover is under pre-loaded spring pressure. Back off the retaining bolts evenly and carefully to avoid sudden spring ejection. Atlas Copco 60°C Thermostatic Valve Service Kit 2901044700 (4) Application Scope This genuine service kit is a standard factory-specified component for medium-to-large Atlas Copco industrial air installations, specifically optimized for: Atlas Copco GA series oil-injected screw compressors (Highly common in GA55 and GA75 platforms fitted with 60°C thermal configurations). Automotive assembly plants and heavy manufacturing facilities. Electronics packaging and high-precision cleanrooms. Central air stations operating under demanding multi-shift schedules. Atlas Copco 60°C Thermostatic Valve Service Kit 2901044700 (5) FAQ Q1: Is this an original Atlas Copco service kit? A1: Yes, this is a genuine factory-approved Atlas Copco maintenance kit, containing precise OEM components to restore factory-spec thermostatic response. Q2: Can I use this kit if my compressor currently runs an 83°C valve? A2: No. This kit is strictly calibrated for 60°C opening configurations. Replacing a higher temperature valve with a 60°C kit without consulting technical support may lead to sub-optimal running temperatures. Q3: What are the risks of delaying thermostatic valve maintenance? A3: Delayed maintenance leads to sluggish valve response, risking sudden emergency high-temperature shutdowns, faster oil oxidation, and moisture buildup within the compressor airend. Q4: Does the kit come with all necessary gaskets? A4: Yes, the kit includes the primary 1202586902 element along with all required high-temperature gaskets, springs, and O-rings found under the 1622707002 sub-assembly for a comprehensive rebuild.
