Eaton With the Snap-To-Connect (STC) Direct Porting option, the fitting profile is machined into the SCU housing, eliminating the need for extra STC fittings. This revolutionary and porting technology provides leak-proof sealing and has operating pressure capability exceeding 4500PSI (310bar). STC Direct Porting is available with Series 5 and Series 10 Steering Control Units. 24 EATON Steering Catalog C-STOV-MC001-E2 September 2011 Benefits • STC Direct Ports provide a great opportunity for significant cost savings compared to threaded fittings • Eliminates the need for assembly tools during installation • Eliminates installation variability • Improves ergonomics - reduces installer effort to connect • Improves serviceability • High quality, leak-proof seal • Eliminates connector leakage • Compact design and overall lighter weight
Steering Control Units—Series 5 Product Description The new Series 5 steering control units (SCU) are exciting new products designed for low flow, low pressure applications. The Series 5 units are available in two compact designs: Option 1: Square Housing (Mount) Unit with Side Ports Option 2: Round Housing (Mount) Unit with End Ports In addition to the installation flexibility provided by the two options above, this new family of products has best in-class steering feel and provides crisp centering. These units also have better efficiency (lower pressure drop) than competitive units. Power Beyond Models—Optional power beyond steering control units supply steering and flow to auxiliary valve functions. The power beyond unit is used in open center (fixed displacement pump) systems in the medium pressure range. When not steering, the power beyond unit directs all inlet flow to the excess flow port (power beyond) for use in the auxiliary circuit. Once steering is initiated, and since steering has priority, inlet flow will be diverted to the steering circuit as required. Flow out the excess flow port (power beyond) and tank port will vary or stop depending upon the steering requirement. The tank port of the steering unit has flow only when steering is operating.
