276-03205

Part number 276-03205 from Siemens belongs to the Flowrite 599 Series, designed as a three-way mixing control valve assembly. This assembly effectively manages flow configurations in various applications. The integrated actuator model is the SKD82.51U, functioning using electro-hydraulic principles while utilizing a spring return mechanism. This enhances reliability in actuation.

The valve operates at a voltage rating of 24 Vac ±20%, allowing for compatibility with standard electrical systems. It supports input voltage frequencies of either 50 or 60 Hz. The assembly is built to endure environmental conditions, reflected in its IP54 rating, which offers protection against dust and moisture. The humidity operational range spans from 5% to 95% RH, signifying its capability to function in different atmospheric conditions.

Its construction utilizes bronze trim material, ensuring durability while exposed to various operating conditions. The valve size measures 1-1/2 inches (40 mm), making it suitable for a range of installations. With a flow coefficient (Cv) of 25, the valve can manage considerable flow rates effectively.

The control signal is designed to be floating (3-position), enabling adaptive valve positioning. This valve also features a linear flow characteristic, which assists in providing predictable flow control across varying conditions. The run times are recorded at 120 seconds for opening and only 8 seconds to spring return to its closed state, enhancing operational efficiency.
