Danfoss 003N-7252RA Temperature Regulator

As a seasoned technician, you know that keeping cooling systems within precise parameters is non-negotiable for equipment longevity. The Danfoss 003N-7252RA Temperature Regulator (AVTA 20) is a professional-grade, self-acting thermostatic water valve engineered for heavy-duty fluid temperature regulation. This 3/4-inch NPT valve operates entirely without electricity or compressed air, making it a "fit and forget" solution for industrial process control and HVACR cooling circuits. With a setpoint range of 77-149F (25-65C), it is specifically designed to open on rising temperature, ensuring maximum flow through your heat exchanger or condenser exactly when the thermal load increases. The brass valve body and pressure-relieved design ensure that fluctuations in water pressure don't throw off your regulation accuracy. Whether you are piping this into a hydraulic station, a sterilizer, or a high-demand chilled water system, the force-compensated spindle provides smooth, proportional control that is naturally insensitive to dirt and mineral buildup.

• No Power Required: Operates mechanically via a hermetically sealed thermostatic element, providing fail-safe cooling even during electrical outages.
• High Precision Regulation: Maintains a constant temperature setpoint within the 77-149°F range to prevent equipment overheating and scale formation.
• Balanced Valve Design: The pressure-relieved bellows ensure the opening degree remains consistent regardless of differential pressure changes across the 3/4" orifice.
• Reliable Performance: Forged brass construction stands up to aggressive water conditions and demanding mechanical environments.

• Can this be used for steam applications? No, this specific model is designed for water flow regulation and neutral brines in cooling applications where the valve needs to open as the sensor warms up.
• Does it require a specific mounting orientation? The regulator is highly versatile and can be installed in any position, though it is standard practice to ensure the sensor is fully immersed in the flow to provide accurate 149F maximum setpoint tracking.
• What happens if there is dirt in the line? The AVTA series is specifically engineered to be insensitive to dirt, as the bellows-driven spindle provides high closing/opening force to clear small particulates.
