XDF Valve Block Mounted Pressure Filter

Specifications

XDF Valve Block Mounted Pressure Filter

1. This filter can be installed directly on the valve block, it makes the system more compact, and the space is saved and has the small flow resistance, high pressure resistance etc. characteristics, which can meet the various application requirements from the customers (Can replace Hydac valve block mounted pressure filter).

2.Filter basic construction
The filter is composed of matching filter element and spin-on housing; there is drainage steel plug at the bottom of the filter.
1. Wide range of supply for filter, filter element and other combined filtration equipments
2. Compltely interchangeable with over 500 international brand originals
3. Very competitive price and fast delivery time
4. Making strictly in accordance with ISO, DIN, IDF and 3A standards, quality comply with GMP requirement.
5. Imported filtration materials
2.1 Housing material
Filter bowl material: Carbon steel 
2.2 Seals
Perbunan (=NBR) (-30~+ 120°C );  Viton=FPM(-20~+ 200°C )
2.3 Filter element
Filter medium material
High strength carbon steel skeleton
2.4 Optional accessories
Drainage plug
2.5 Type of connection (chosen according to the filter type)
Metric threaded connection

4.The total filter assembly pressure drop is the sum of housing and element pressure drop,filter selection calculated as per the following curves.
4.1 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. 

                                  Filter housing pressure drop (with valve block)

4.2 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.
                      Clean filter element pressure drop

DFFILTRI was founded in 1995, since then we devoted ourselves to research, develop and produce many kinds of hydraulic filters, air filters, hydraulic system accessories, cleaning and filtration equipments, pump valve components. DFFILTRI is our brand, which enjoys high popularity and it has successfully achieved the position both in China and across the world.
DFFILTER filtration technology testing center covers a total area of 450 square meters, of which, clean room area of 200 square meters, and cleanliness is up to 100,000 levels. The centre undertakes filtration technology inspection and testing for in-house science research, production and industry service.   
On-line particle counter of BETAB-HIAC/POYCO type (8000A/8000S) provided by HIAC/POYCO company in USA, and its supporting machine"Multi-pass test" and "single-pass test" implements ISO16889 new standard and other international standards perfectly.
Testing center also has the developed equiment for filter performance testing, which can make the comprehensive examination for filter element/cartridge performance. These can insure that company's filter with high capacity, long life, high reliable in full compliance with our customer's  requirement.
The testing centre can take 7 tests of hydraulic filter performance evaluation, they are as follows:
ISO 2941 Verification of collapse/burst resistance
ISO 2942 Verification of fabrication integrity and determination of the first bubble point
ISO 2943 Verification of material compatibility with fluids
ISO 3723 Method for end load testing
ISO 3724 Verification of flow fatigue characteristics
ISO 3968 Evaluation of pressure drop versus flow characteristics
ISO 16889 Multi-Pass method for evaluating filtration performance
