Crossover For Maier Rotary Joint H Series
♦This product is a dedicated crossover for Maier Type H series rotary joints.
♦Maier Type H rotary joints are categorized into basic structural types (Type H and Type HW) and reinforced structural types (Type HWA, HWB, and HWX).
♦It features a housing flange with a bolt-connected flat seal, and the main body is made of ductile iron.
♦For applications DN100 and above, the HWA type utilizes a welded steel structure.
♦The seal ring is metal-impregnated, making it suitable for high-pressure working conditions, and the main bearing is equipped with anti-reverse rotation protection.
♦In terms of structural adaptation, the HWA and HWB types are designed for rotating inner tubes, while the HWX type is for non-rotating inner tubes.
