For Hydraulic Pressure Compensated Proportional Flow Regulator Cartridge equivalent to HydraForce PV70-30, AAK received re-order from Brazilian client

China [CN]

Today, we’d like to introduce another Pressure Compensated Proportional Flow Regulator Cartridge equivalent to HydraForce standard part PV70-30.  

It is a solenoid operated, pressure compensated, spool type, normally closed, priority type proportional flow regulator.

The features of this proportional priority flow control valve:

l Excellent linearity and hysteresis characteristics.

l Hardened spool and cage for long life.

l Optional coil voltages and terminations.

l Efficient wet-armature construction.

l Cartridges are voltage-interchangeable.

l Unitized, molded coil design.

l Coil waterproofing standard.

l Manual Override option.

A customer in Brazil placed a test order for 10 pcs last June in 2022, along with PV72-30. After 1 year of testing, it proves that the function and performance of AAK hydraulic proportional priority flow control valve benchmarked the quality of HydraForce PV70-30. Today, we received their re-peat order for 1,000 pcs, same qty as the repeat order placed for PV72-30 in July.
