KDF-V

Product catalog summary

Technical Specifications:
The document details the specifications for a magnetic piston pressure gauge used in filtration systems, covering standard and special versions of filter elements, units, caps, venting, draining devices, and connection types. Materials include various steel grades and alloys, with options for magnetic filters and heaters.

Design and Certification:
The design complies with standards like EN 1092-1 and certifications such as Lloyd's Register and DGRL 2014/68/EU. It highlights the need for compatibility between the medium and vessel materials and a danger analysis before startup.

Application Areas:
The KDF duplex filter is suitable for both pressure and suction modes, allowing continuous operation during cleaning and on-site retrofitting. It is versatile for coarse and fine filtration.

Safety Instructions:
Filters with lever locks are not suitable for hazardous media. The document advises using screws and nuts for lid closures in such cases and stresses the need for conformity assessments for changes in operating conditions.

Commissioning and Operation:
Commissioning involves opening the pressure equalization line and ensuring all components are secured. During operation, switch filter halves when dirty and ensure pressure equalization before switching.

Cleaning and Maintenance:
Cleaning requires depressurizing the filter side, removing the filter cap, and checking gasket integrity. Regular switching is recommended for corrosive media.

Technical Data and Dimensions:
The document provides detailed dimensions and specifications for various filter sizes, including flow rates and filter areas, noting that dimensions for welded filters may differ.

Overview:
The document provides technical specifications and operational guidelines for the KDF-V duplex filter by Krone Filter Solutions GmbH, covering design, safety instructions, commissioning, operation, cleaning, materials, and certifications.

Specifications:
The duplex filter consists of two identical single filters connected via a valve-switching device, operating in parallel or individually. It is available in standard and special versions, with options for different filter elements and materials, designed for quasi-static operation with a maximum differential pressure of 2 bar.

Safety Instructions:
Filters with lever locks are unsuitable for hazardous media. For such applications, screws and nuts should be used as lid closures. The use of KDF-V filters for gases requires manufacturer review. Conformity assessment as per PED 2014/68/EU is necessary for changes in operating conditions.

Commissioning:
Before commissioning, ensure pressure equalization, check all screws and locks, and verify the position of the switching lever. Both filter chambers should be filled simultaneously to avoid rapid pressure equalization.

Operation:
Ensure the container is depressurized before maintenance. Switch to the clean filter half when the other is dirty. Open the pressure equalization line before switching and close it afterward. Clean the filter element only after releasing pressure from the chamber.

Cleaning:
Depressurize the filter side to be cleaned, loosen the filter cap, and check the lid gasket integrity. Do not leave opened filters unattended.

Materials:
The filter housing and lid are made from materials like DIN EN GJS-500-7, stainless steel, and others. Various materials are available for different components, including O-rings and perforated plates.

Technical Data:
The document includes detailed dimensions and specifications for different filter sizes and configurations, outlining available options for additional features like heaters and differential pressure indicators.

Certifications:
The filter is certified under various standards, including Lloyd’s Register Type Approval and conformity evaluation according to 2014/68/EU.

Application Areas:
The KDF duplex filter is suitable for pressure and suction modes, offering continuous operation during cleaning. It is versatile for coarse and fine filtration in various industrial applications.

Document Overview:
This document is a Type Approval Certificate issued by Lloyd's Register EMEA for Krone Filter Solutions GmbH, covering single, duplex, and automatic filter types: KSF, KMF, KDF-K, KDF-V, KAF, and KRF. The certificate is valid from 09 September 2016 to 08 September 2021.

Specifications:
The document specifies materials and temperature ranges for various filter types. Spheroidal cast iron is suitable for temperatures from -10 to +300°C, austenitic stainless steel for -196 to +300°C, duplex stainless steel for -40 to +250°C, and carbon steel for -40 to +100°C. Pressure reductions at elevated temperatures should be considered.

Media Compatibility:
The filters are compatible with various media depending on the type. KAF and KRF are suitable for water and seawater, while KSF, KMF, KDF-K, and KDF-V can handle MDO, oil, nitrogen, water, and seawater.

Standards and Conditions:
The filters must comply with Lloyd’s Register Rules and Regulations for the Classification of Ships, July 2016. The manufacturer's installation instructions must be followed, and the filters are not to be used in applications with significant shock or vibration loads.

Approval Documentation:
The document includes a list of reviewed documents for compliance with Lloyd’s Register’s Type Approval System Procedure TA14, including product catalogues, data sheets, and parts lists for various filter types.

Testing and Inspection:
The document details hydrostatic burst pressure tests conducted on various filter types, witnessed by an LR Surveyor. Final acceptance of the items depends on satisfactory survey and testing.

Supplementary Terms:
Type Approval certifies that a representative sample meets the design criteria for specified use. It does not imply approval for other uses or products not conforming to the sample. Compliance with manufacturer recommendations and relevant regulations is required.

Brief description and function The duplex ﬁlter, comprises two identical single ﬁlters, connected via a valve-switching device to a ﬁlter side or can be operated in parallel. Medium to be ﬁltered enters the ﬁlter basket from the top and ﬂows through the insert inside out. Dirt thus remains in the ﬁlter element. • The pressure equalization line must be opened prior to commissioning. • Check whether all screws and locks have been tightened properly. • Check the position of the switching lever (here is an incised on the shaft, which deﬁnes the direction of ﬂow and / or shows ”in operation“ on the...

Material / housing Caution: Since it is a pressure vessel, it is important to ensure that the container is without pressure prior to beginning of maintenance. 1. As soon as the ﬁlter half is dirty (increasing differential pressure on the indicator or decreasing operating pressure in the system), the clean ﬁlter half is put into operation by gradual switching. 2. Importand: The pressure equalization line must be opened before the switch-over. If this instruction is not followed, damage can occur during switching. After switching over the pressure equalization line close again. 3. Proceed with...
