Isotherm SFD00034AA – Water Mixing Thermostat Kit for SPA 15/20/25/30/40 (B-Type Valve)

The Isotherm SFD00034AA is an OEM thermostatic water-mixing kit engineered for SPA-series marine hot-water systems rated at 15, 20, 25, 30 and 40 liters. Designed for installations using the B-type mixing valve, the kit controls the ratio of hot and cold water to deliver a stable mixed-water output temperature. It prevents overheating, thermal spikes and scalding while maintaining consistent comfort throughout the vessel’s plumbing network.

The thermostatic assembly is built from marine-grade, corrosion-resistant materials capable of withstanding continuous exposure to heat, moisture and vibration. Its internal temperature-sensitive cartridge reacts dynamically to changes in inlet-water temperature, keeping the outlet temperature within a safe and predictable range. This kit serves as a direct OEM replacement for worn or failing mixing valves in SPA systems and is typically installed during system upgrades, refurbishment or heater maintenance.
