| Fluid Temperature Range | -20 to +80 °C (operation); -40 to +90 °C (storage) |
| Noise Level (Direct-Acting) | ≤63 dB(A) at 1 m distance under rated operation |
| Noise Level (Pilot-Operated) | ≤65 dB(A) at 1 m distance under rated operation |
| Mounting Standard | ISO 3019-2 flange; optional foot mounting for some models |
| Shaft Connection | ISO 4162 splined shaft; keyed shaft available on request |
| Seal Materials | NBR (standard, for mineral oil) and FKM (optional, for synthetic oil) |
| Weight Range (Direct-Acting) | 8-12 kg (depends on displacement) |
| Weight Range (Pilot-Operated) | 10-35 kg (depends on displacement and control type) |
| Control Type (PV7-A Series) | Direct-acting pressure compensation |
| Control Type (PV7-C/D/N/W Series) | Pilot-operated pressure/flow control |
| Pressure Rise Response Time | 40-60 ms (both direct-acting and pilot-operated) |
| Housing Material | GG25 cast iron (high strength and vibration resistance) |
| Rotor and Stator Material | 42CrMo4 alloy steel (quenched & tempered for high hardness and wear resistance) |
| Vane Material | Wear-resistant powder metallurgy alloy (self-lubricating and anti-seizure) |
| Service Life | 8000-10000 operating hours (depends on oil cleanliness and maintenance) |
| Case Drain Flow Range (Direct-Acting) | 1.5-2.5 l/min at rated pressure (varies with displacement and pressure) |
