Principle and Function within the STAUFF System<\/h3>\n

The STAUFF Heavy Series Cover Plate Type DPAD<\/strong> is an essential component in fastening systems for hydraulic pipework, specifically developed for STAUFF Groups 4S-D (4S) and 5S-D (5S). Designed to provide maximum strength, this plate ensures correct and secure locking within the Heavy Twin Series assembly.<\/p>\n

Construction and Dimensional Features<\/h3>\n

The component is available for two main size groups. Group 4S has an overall length (L1) of 115 mm (4.53 in) and a centre distance (L2) of 90 mm (3.54 in), with a width (B) of 30 mm (1.18 in) and a thickness (S) of 8 mm (0.31 in). The hole diameter (\u00d8D) is 11 mm (0.43 in). Group 5S, intended for larger configurations, provides an overall length (L1) of 145 mm (5.71 in) and a centre distance (L2) of 120 mm (4.72 in), while maintaining the same width of 30 mm, thickness of 8 mm and hole diameter of 11 mm.<\/p>\n

Material Specifications and Surface Finishes<\/h3>\n

The STAUFF Heavy Series Cover Plate Type DPAD is available in a wide selection of materials, identified by precise codes to suit specific operating conditions. Code W1 identifies uncoated carbon steel, while W2 indicates phosphated carbon steel. Code W3 corresponds to zinc\/nickel-plated carbon steel, which is the standard finish option for DPAD plates in the North American market. For environments subject to high levels of corrosion, stainless steel variants are available: W4 for V2A Stainless Steel (1.4301\/1.4305, equivalent to AISI 304\/303) and W5 for V4A Stainless Steel (1.4401\/1.4571, equivalent to AISI 316\/316 Ti).<\/p>\n

Integration with the SPAD Weld Plate<\/h3>\n

Within the same Heavy Series, the system is combined with the Type SPAD Weld Plate, which is also compatible with Groups 4S and 5S. SPAD plates have overall lengths (L1) of 130 mm for Group 4S and 160 mm for Group 5S. The threaded components of the SPAD Series are available with ISO Metric Thread (code M, M10 specification) or Unified Coarse Thread UNC (code U, 3\/8-16 UNC specification). The standard finish for SPAD weld plates in North America is W2.<\/p>\n

Product Coding System<\/h3>\n

The ordering system allows the exact required component to be configured. Cover plate codes use the prefix DPAD, followed by the group (4S or 5S) and the material code (W1 to W5), generating codes such as DPAD-4S-W1. Weld plates additionally include the thread specification, resulting in order codes such as SPAD-4S-M-W1.<\/p>\n
