para águapara ar comprimidopara vapor

Short Description
DN40 high temperature resistant rotary joint. Model Type: Universal Rotary Union / Swivel Joint. Inner Diameter: 40mm (DN40 / 1.5") . Performance: ≤10 RPM, ≤1.0 MPa, ≤200°C. Floating Angle: 20° (Self-aligning). Applicable Media: Water, Air, Saturated Steam. Advantage: Low maintenance, Leak-proof, Cost-effective.

Overview
The DN40 universal rotary union is a low speed single passage rotating joint designed for reliable fluid transfer between stationary supply lines and rotating equipment. With a 40mm inner diameter (1.5 inch nominal bore) it delivers high flow capacity while maintaining a compact footprint. The self-aligning design with 20° floating angle automatically compensates for minor misalignment, reducing shaft stress and extending seal service life.
