Delta-Y delivers space & weight savings; enables more efficient installation, operation & maintenance than flanged/welded assemblies


Victaulic Delta-Y Assembly

Victaulic, the world's leading manufacturer of mechanical pipe-joining systems, introduces the Style DLY Delta-Y assembly, a combination of pre-assembled Victaulic cast grooved fittings, rigid couplings and butterfly valves. The Delta-Y assembly is designed specifically for bulk cement/barite systems on offshore oil platforms and is also ideal for drilling mud and other associated systems. The Delta-Y assembly offers quick and simple installation, space and weight savings, efficient operation and reduced maintenance downtime.

The Victaulic Delta-Y assembly speeds fitting and valve installation. Each pre-assembled unit is delivered complete with all fittings and valves oriented correctly as required by system design. The unit is joined to the piping system with three Style 107 QuickVic® rigid couplings, easing installation.

In comparison to flanged and welded assemblies, the Victaulic Delta-Y offers significant weight and space savings. At less than half the weight of lug butterfly valves with flanges, Vic-300 MasterSealâ„¢ butterfly valves provide considerable weight reduction. Weight savings can exceed 200 pounds (91 kilograms) per delta. In addition, the Delta-Y can reduce the overall delta length by 1 foot (300 millimeters).

The Delta-Y assembly improves the operational efficiency of cement/barite piping systems. The offset disc within the valves provides a larger flow area for more efficient flow, low operating torque and leak-tight sealing. The fittings maintain full wall thickness and have a smooth inner flow path to minimize abrasion and blockages. The Delta-Y assembly is also available with 5D Long Sweep fittings that increase fitting life and maximize flow capabilities for faster cementing operation.

The Delta-Y assembly can reduce maintenance downtime by up to 50 percent, as each coupling serves as a union for rapid valve and fitting replacement.

The Victaulic Style DLY Delta-Y assembly is available in 5- and 6-inch pipe sizes (125 and 150 millimeters) and has a pressure rating of 300 psi (2,065 kPa).
