Please refer to the dimensions table below for specific size and bolt configuration details.
Dimensions Table (MM)
Note: Please note dimensions may vary at our discretion. All measurements are in millimeters (MM).
Bolt Configuration Details
Large Size Bolt Pattern: All sizes use M16 bolts with varying quantities (6-22 bolts) and different lengths based on size requirements. M1 and M2 configurations provide dual bolt patterns for enhanced structural integrity.
Design Variations
Stepped vs Straight: Some sizes (DN300, DN400) are available in both “Stepped” and “Straight” configurations to accommodate different installation requirements and pipe connection methods.
