The 274-03076 is an efficient two-way control valve assembly designed by Siemens within their Flowrite 599 Series. Functioning with an electro-hydraulic actuator (model SKD62U), it operates at a voltage of 24 VAC, suitable for nominal input frequencies of 50 or 60 Hz. The valve has an indoor-only enclosure rating of NEMA 1, making it ideal for controlled environments.
With a size of 3/4 inches (20 mm), this valve is compact yet effective for various applications. The actuator generates a nominal force of 225 lbf (1000 N) for the normally closed port, while achieving up to 258 lbf (1150 N) for the normally open port. For preserving system efficiency, the assembly meets ANSI Leakage Class IV standards, which limits leakage to just 0.01% of the Cv value.
Constructed with durability in mind, the actuator housing is made from die-cast aluminum, ensuring longevity and resistance to environmental factors. The valve's trim is crafted from stainless steel, while the valve body itself is composed of bronze, providing further strength and longevity in various operational settings. The flow coefficient of 6.3 Cv indicates the valve's capacity to handle fluid flow effectively, making the Siemens 274-03076 a dependable choice for precise flow control.
