The V series quick-release couplings are particularly prevalent in the East Europe and German markets and they are interchangeable with
the main local manufacturers. Their particular structure allows a wide range of available threads:
this eliminates the need for adaptors and therefore also a reduction in costs. Mechanical strength and the impossibility of an accidental release
of the male from the female makes very safe the use of these screw-on couplings: they are very suitable in heavy hydraulic applications
either for adverse environment conditions or for high work pressures. Fields of application: industry, iron industry, oil plant, earth moving
machinery and similar service vehicles.
Interchangeability: with similar couplings of the major German
manufacturers, with FASTER CVV series,
STUCCHI VD series, DNP PVV3 series
