Sporlan 4036-00 ME25S290 Valve

The Sporlan 4036-00 ME25S290 is a heavy-duty, pilot-operated Solenoid Valve engineered for large-capacity liquid, suction, or discharge service in commercial refrigeration and air conditioning systems. This model features a 1-1/8" ODF sweat connection and is specifically optimized for R-410A refrigeration systems. As a normally closed solenoid valve, it remains shut until energized, ensuring positive shut-off and preventing refrigerant migration during off-cycles. A critical feature for field technicians is the manual lift stem, which allows for manual opening of the valve during system evacuation, commissioning, or emergency troubleshooting when power is unavailable. This unit serves as the direct replacement for Sporlan 3672-00, maintaining the same footprint for seamless retrofitting. Built with a synthetic seated main disc and a stainless steel pilot member, the ME25S290 provides reliable performance under high-pressure differentials typical of modern high-efficiency HVACR equipment.

Key Technical Benefits

• Manual Override Capability: Integrated manual lift stem allows technicians to bypass electrical control for charging or recovery operations.
• High-Pressure Compatibility: Specifically rated for R-410A high-pressure refrigerant applications found in modern VRF and rooftop units.
• Optimized Flow Dynamics: High flow capacity (Cv) minimizes pressure drop across the liquid line, maintaining system efficiency.
• Durable Construction: Features a rugged, hermetic design to prevent external leaks and withstand harsh mechanical room environments.
• Direct Retrofit Path: Engineered as the exact replacement for the 3672-00, ensuring zero-clearance issues during component swaps.

Common Installation and Compatibility Questions

Is the ME25S290 compatible with refrigerants other than R-410A?
While optimized for R-410A, this valve is generally compatible with other common HFCs and HCFCs; however, flow capacities must be recalculated based on the specific refrigerant's properties and pressure drop requirements.

What coil should be used with the Sporlan 4036-00?
This valve body is designed to work with standard Sporlan MKC-2 solenoid coils. Ensure the voltage and frequency of the coil match your control circuit specifications (e.g., 24V, 120V, or 240V).

How does the manual stem affect normal operation?
For the valve to operate automatically via the solenoid coil, the manual stem must be turned to the full down (retracted) position. If the stem is turned up, the valve will remain mechanically locked open.
