VKCH side plate high pressure filter series

Purpose: The side-plate high-pressure filter is used in the high-pressure valve table in the hydraulic and lubrication system to filter out mechanical impurities and chemical reaction products mixed in the medium, keep the filtered medium clean, and prevent pollution, abrasion, and blockage.
Design pressure rating: 31.5Mpa
Nominal flow rate: 1~110L/min
Filter material: carbon steel
Filtration accuracy: 1um lower

Filter element pressure drop curve

The pressure drop characteristic curve of the filter element is suitable for mineral oil with a kinematic viscosity of 30mm²/s, and the pressure drop changes in proportion to the viscosity。

Selection example
公式
ΔP total = ΔP shell + ΔP filter element × (viscosity mm²/S÷30mm²/S)
举例:
Flow 300L/min, accuracy 10u, 46# hydraulic oil
Selection VKCH660
ΔP shell=0.55bar, ΔP filter element=0.35×(46mm²/S÷30mm²/S)=0.54
ΔP总==0.55+0.54=1.09bar
