Modular, Low-Flow Valve Controls Compact Equipment

April 12, 2006

Unique features of the VO40 valve minimize function drift, and precise metering ensured by machined lands provides repeatable control. Putting this level of precision into the machine functions guarantees productivity, allowing every job to be done quicker, safer and on time. Flexible performance options and enhanced serviceability make this product line well-suited for use on a wide range of compact equipment including implements, attachments, skid-steer loaders, forklifts, trenchers, directional borers, agricultural machinery, small cranes and aerial platforms.

The product line features a unique lock-valve section option that can be used in applications where no leakage or function drift is allowed. Application of this lock-valve can save OEMs hundreds of dollars per installation by eliminating the need for complex accessory valves. In addition:

· A complex series of metering notches on the spool lands let the operator actuate functions simultaneously, providing for cycle-time efficiency and secure operation. In addition, these notches can be tuned for all types of operations including both resistive loads (meter in) and negative loads (meter out). The design allows the spool to be inserted into either end of a symmetrical housing.

· The slotted design of the valve sections allows users to easily add or change sections and functionality. This feature is important in markets where aftermarket and OEM options are available, and can be added as required at a later date. Unlike many other similar designs, sections of the VO40 can be removed without taking apart the entire assembly.

· An enclosed handle assembly protects the spool and spool-seal area from contamination and potential corrosion, while the robust trapped-seal design in the VO40 ensures reliable operation. In addition, using the same generous-size section seals in all locations eliminates the chances of incorrect assembly during service or restacking.

Additional benefits

Besides the savings provided by the lock-valve option, a number of other benefits are offered by the VO40 over competitive solutions:

· The improved controllability supplied by the VO40’s unique spool design reduces cycle time by as much as 10 %, increasing application efficiency. · Lower pressure drops (by as much as 10%) compared to other valves of similar size means real savings. Decreased fuel consumption and improved efficiency reduce system-cooling requirements and in some cases may eliminate the need for expensive hydraulic cooling systems.

· Large cross-section seals using the latest in material technology provide both durable and reliable operation, reducing downtime and expensive clean ups.
