Comoso Controlled Motion Solutions

QVHZO and QVKZOR are 2 or 3 way flow proportional valves, direct operated, with position transducer which provide compensated flow control according to the electronic reference signal.

They operate in association with electronic drivers, see section 2 which supply the proportional valves with correct current signal to align valve regulation to the reference signal supplied to the electronic driver.

They are available in different executions:

• T, with integral position transducer;
  
• TE, -TES, as -T plus analogue (TE) or digital (TES) integral electronics;
  

The flow is controlled by a throttle , directly operated by the proportional solenoid . The mechanical pressure compensator  keeps a constant Delta p across the throttle , thus the regulated flow is independent to the load conditions.

The integral electronics  ensures factory presetting, fine functionality plus valve-to valve interchangeability and simplified wiring and installation.

The electronic main connector is fully interchangeable for –AE and –AES executions.

Standard 7 pin connector is used for power supply, analog input reference and monitor signals.

12 pin connector is used for option /Z (TES).

Following communication interfaces  are available for the digital -TES execution:

• PS, Serial communication interface for configuration, monitoring and firmware updating through Atos PC software
  
• BC, CANopen interface
  
• BP, PROFIBUS DP interface
  

The valves with -BC and -BP interfaces can be integrated into a fieldbus communication network and thus digitally operated by the machine control unit.

The coils are fully plastic encapsulated (insulation class H) and valves have antivibration, antishock and weather-proof features.
