The VMV IN40M is an inline steam mixer, also functioning as an air vent, designed for precise steam-water mixing applications. It features a DN40 flanged connection, is PN25 rated, and operates within a pressure range of 0.5-1.7 MPa with a maximum temperature of 207°C. The unit has a compact cast body design, a multi-port cylindrical head, and a visible IN40M model marking. While primarily a mixer, its design also allows for air venting. It is suitable for steam systems requiring precise mixing of steam and water to achieve desired output conditions.
