At pump inspections like records of pump curves in dependency of pressure, we recommend our loading valve with integrated measuring turbines as a useful testing device.
Hydrotechnik loading valve with two handles:
•Measuring range: 12 to 600 l/min
•Error limit: ± 2,5 % of the actual value at 30 cst (mm2 s-1)
•Viscosity range: 3 to 200 cst (mm 2 s-1)
•Operating pressure: max. 420 bar
•Operating temperature: -20 °C to +80 °C (short term to 100 °C)
•Connections: ISO 228-G1 1/4 (Inlet / Outlet)
•Dimensions: 305 x 146 x approx. 208 mm (LxWxH)
•Media application: Suitable for hydraulic- and other oils on
•mineral oil basis. |
