MA-DKZOR-T Hydraulic Proportional Direction Valve High Frequency MA-DHZO-T 06 and 10
High performance hydraulic proportional valves with position transducer and positive spool overlap for best accuracy and dynamics in directional controls and not compensated flow regulations.
They are specifically designed to achieve high speed closed loop controls and to implement alternated Pressure (Force)/Flow controls - options /S* coupled with spools ‘Q’ or ‘V’.
The 4-way spool , sliding into a 5-chambers body , is directly operated by the proportional solenoid and it is controlled in closed loop position by means of the LVDT transducer feedback .
The electronic driver supplies the proportional valve with proper current to align valve regulation to the reference signal, the integral execution has rugged construction and grants factory presetting for valve-to-valve interchangeability.
Size: 06 and 10
Max flow: up to 80 and 170 l/min
Max pressure: 350 bar (DHZO)315 bar (DKZOR)

Above performance data refer to valves coupled with Atos electronic drivers, see section 2
The flow regulated by the directional proportional valves is not pressure compensated. Thus it is affected by the load variations. To keep costant the regulated flow under different load conditions, modular pressure compensators are available (see tab. D150)
For different P, the max flow is in accordance to the diagrams in sections 14.2 and 15.2
0-100% step signal
Competitive: The international advanced technology and process, the coil import from Germany, can replace Atos, Rexroth, Yuken and many other brand, the form and installation can completely interchangeable.
Applications: Hydraulic system, marine, palstic machine and many other hydraulic systems and machines.
We supply our valves to many OEM customers, the quality is the No.1 in China.
