337NC-04316-35

Siemens presents its 337NC-04316-35 part, a pressure independent control valve tailored for precision flow regulation. This valve has a diameter of 2 inches (50 mm), making it suitable for various plumbing applications where consistent performance is vital. It features a robust construction with a ductile iron body paired with a stainless steel stem, ensuring longevity and resistance to wear.

The actuator used is model 599-03617NC, responsible for achieving reliable operation at an input voltage of 24 Vac/24 Vdc with a tolerance of ±20%. This piece is designed to sustain a close-off pressure reaching up to 100 psi, contributing to its versatile application in demanding environments. The valve showcases a maximum preset flow capacity of 35 gallons per minute (GPM), which is particularly beneficial for systems requiring uniform flow rates.

In terms of performance, the valve is rated for a rangeability of at least 100:1, allowing for flexible control across diverse operational conditions. Leakage is minimized, classified under ANSI Leakage Class IV, which denotes an insignificant leakage rate of approximately 0.01% of Cv. Furthermore, this valve is built to withstand a medium temperature range of 1°C to 120°C, providing adaptability during diverse temperature conditions. Its IP54 protection rating indicates it is designed for NEMA Type 1 environments, offering sufficient dust and moisture resistance suitable for indoor applications, while maintaining a maximum humidity of 95% RH in non-condensing conditions.
