GU-H-63x10-F-P Hydraulic Pressure Line Filter/Ductile Cast Iron Filter Top Cover Material

Specifications

                         GU-H-63x10-F-P Hydraulic Pressure Line Filter/Ductile Cast Iron Filter Top Cover Material

1. Product introduction

GU-H series filter is installed in the pressure pipeline of hydraulic system, used to clear away or prevent the pollutants invading generated in the hydraulic oil, prevent valve core stuck, throttling the small holes, cracks and damp holes blocking, and excessive wear of hydraulic components etc. failures happening; This series of filter is equipped with the bypass valve and check valve, accordingly have the dual protection, also with differential pressure indicator, when the element is clogged to oil inlet/outlet and pressure difference reaches 3.5bar, the signal is sent out, the filter element should be cleaned or replaced.  

2. Product characteristics

3.2 Technical Data

4. Mounting Size

4.1 Threaded connection 

4.2 Flangede connection

5.  Product characteristic curves           

The total filter assembly pressure drop is the sum of housing and element pressure drop,filter selection calculated as per the following curves.

5.1 Housing pressure drop / flow rate characteristic curves 

Housing pressure drop /flow rate characteristic curves are according to ISO3968, and suitable for the mineral oil with density 0.86 kg/dm³ and kinematic viscosity 30 mm²/s. 

5.2 Differential pressure / flow characteristic curves of filter element

The characteristic curves of filter element are suitable for the mineral oil with kinematic viscosity 30 mm²/s. Differential pressure and viscosity is proportional.
