UNOX 3 Way Motorized Proportional Control Valve For Hot Oil – 33618

3 Way Motorized Proportional Control Valve for Hot Oil

The UNOX 3 Way Motorized Proportional Control Valve for Hot Oil is engineered for high-temperature thermal-oil circuits and precise flow-mixing or diverting operations. Its heavy-duty construction and smart proportional control make it ideal for industrial heating plants, chemical processes, and energy systems requiring accurate temperature regulation and long-life reliability.

This valve’s GGG-40.3 spheroidal graphite cast iron body and Class IV metal-to-metal tightness provide strength and dependable sealing even under high stress. The Class VI V-pack metal bellows stem seal ensures zero external leakage, while a maximum working temperature of 350 °C (662 °F) and PN25 pressure rating (≈363 psi) cover demanding hot-oil applications. The flanged connections comply with DIN 1092-2 (PN16) for easy, standardized installation.

Driven by a robust electric actuator, the valve operates on 220V AC or 24V DC and is available with an IP54…67 protection rating, safeguarding against dust and water ingress. In case of power loss, the actuator securely holds its last position, protecting both process and equipment. Optional accessories such as limit switches, 0-1 kOhm potentiometers, or 4-20 mA / 0-10 V DC feedback control can be added for advanced automation and integration into modern control systems.
