Proportional Flow Control Cartridge QNPPM33
By Trevor Allen 1st February 2010
These cartridges are utilised in all applications, where constant volume flows over the whole pressure range are required. Thus, for example, the speed of hydraulic motors can be maintained constant with a very small hysteresis or the lowering speed can be controlled independent of the load in the case of lifting functions.
Impressive apart from the excellent linearity and the low leakage is also the compact construction of the valve. The cartridge for the cavity M33 x 2 in accordance with ISO 7789 has been developed for the demanding modular construction. For the new flow control cartridge, the same cavity as for the throttle valve cartridge can be utilised.
