DX-6 is a sectional valve designed for max. operating pressures up to 5000 psi (350 bar) and max. pump flows up to 180 l/min with "Q-inlet". For standard inlets without flow regulator the recommended max. pump flows is 37 gpm (140 Lpm). The valve is available with 1 to 10 working sections per valve assembly.

DX-6 includes as standard a variety of sections, spools, spool controls and additional parts in a modular design. That makes the valve very flexible.

Q-Inlet

Q-Inlet

 N/A The Q-inlet is designed with a flow control (Q-function) that by-passes the major part of the pump flow to tank when the system is idling, still giving access to full pump flow when the working sections are operated. Besides greatly reducing heat generation this also provides improved operating characteristics.

Remote Control

Remote Control

 N/A As remote controlled the valve offers compact design with internal pilot oil supply, solenoids in a compact assembly on one side of the valve and integrated hand levers for manual override/manual operation.

The integrated pilot supply system for the electro hydraulic remote control makes the valve easy to install and gives a reliable remote control function. It is also possible to supply the pilot system externally. The hydraulic remote control can also be configured both for internal and external pilot supply.

Features

N/A The valve is, as standard, setup for both manual and remote control. The manual controlled sections can either be with open spool ends or encapsulated. The encapsulation decreases in a significant way the risk for external leakage and makes the valve well adapted for applications in demanding environment. The spool controls for remote control are generally designed as complete modules for assembling on one of the valve sides.

DX-6 is in first place designed as an open center valve for fixed displacement pumps but can also be configured for variable displacement pumps. It is available with manual, hydraulic or electro hydraulic proportional remote control.

DX-6 can be fully adapted for marine applications. The valve offers excellent operating characteristics, and good controllability on a wide range of machinery due to the specially designed spools.

Low and uniform spool forces are the result of careful balancing of the flow forces.

Applications

Applications

 N/A The DX-6 is ideal for applications where you need excellent control characteristics such as cranes, sky-lifts, garbage trucks, demountable bodies, excavators, telescopic load handlers, skid-loaders, wheel loaders etc.
