Compression Control Hybrid Valve Tech Note

General Description

OVERVIEW The Sauer-Danfoss directional control valves are designed to give customer ﬂexibility

over a broad range of ﬂow and pressure capabilities. Actuator options include a range of levers, cable actuators, hydraulic and pneumatic pilot controls, two-axis joysticks, and electrohydraulic solenoids. Flow rates range from 0 to 100 l/min [26 US gal/min]. Conﬁgurations include compact mono-block and ﬂexible modular styles..

The Compression Control Hybrid Valve is designed to improve the operation of rear loader garbage trucks. It increases the packing ratio, adds more payload capacity and moves the load to provide better weight distribution.

COMPRESSION CONTROL HYBRID VALVE

TYPICAL APPLICATIONS

STANDARD FEATURES • PO check valve that provides ﬂow and pressure to open the telescopic cylinder when

• Rear loader garbage trucks

the tailgate is closed

• Pressure compensator valve to avoid the garbage spring effect during the packing stroke of the telescopic cylinder

• Flexible HIC designs to adapt to vehicle architecture

• Higher capacity with constant refuse density

For more information regarding spool types, actuation options, cabling and electrical options, spool centering and detent options and auxiliary valves, refer to Sauer-Danfoss publication Directional Control Valves Technical Information, 520L0564.
