Raypak 004825F Gas Valve

The Raypak 004825F is a standing pilot liquid propane (LP) gas valve engineered for precision fuel regulation in heavy-duty pool and spa heaters. This millivolt gas control valve is designed specifically for Raypak 206A-406A and Gemini heater series, ensuring seamless integration with existing plumbing and gas lines. Operating on a 750mV thermopile system, it provides reliable mechanical actuation without requiring external power, making it a critical component for remote or off-grid installations. The 3/4-inch NPT inlet/outlet configuration facilitates high-flow capacity, while the internal pressure regulator maintains a consistent manifold pressure required for efficient LP combustion. Built for durability in high-cycle environments, this direct replacement gas valve ensures the pilot flame remains stable, preventing nuisance lockouts and ensuring consistent BTU output across various ambient temperatures. For technicians performing pool heater gas valve replacement, this OEM-spec component ensures the safety and performance standards of the original equipment are maintained.

• OEM Compatibility: Exact replacement for Raypak and Rheem atmospheric heaters using standing pilot ignition.
• Mechanical Reliability: Millivolt operation ensures the heater functions independently of line voltage, ideal for LP pool heater troubleshooting.
• High Flow Rate: Optimized for large-capacity heaters requiring stable pool heater manifold pressure.
• Rugged Housing: Resistant to the corrosive environments typically found in equipment pads and pool sheds.

Common Technical Questions

Can this valve be used for Natural Gas conversions?
No, the 004825F is calibrated specifically for liquid propane (LP). Using this on Natural Gas applications will result in incorrect manifold pressure and potential burner damage. For NG units, use the manufacturer-specified NG variant.

What should I check if the pilot won't stay lit?
First, verify that the 750 millivolt thermopile is generating at least 450-500mV under load. If the voltage is correct but the standing pilot LP gas valve drops out, the internal electromagnetic coil may be failing.

Is a transformer required for this valve?
No, this is a millivolt gas valve. It generates its own operating signal from the heat of the pilot flame acting on the thermopile, eliminating the need for a 24V step-down transformer.
