SCRAPER MADE OF PE
PE - HD, PE - MD, PE - LD, PE - el
In cooperation with a partner for the injection molding technology, we have access to newly developed scrapers made of PE. The scrapers are used in the fields of chemistry, industry, food technology and also in the disposal.
Qualities available are PE-HD (color RED), PE MD (color BLUE and ORANGE), PE-LD (color white natural) and PE-el (electrically conductive).
The sale of scrapers made of PE (formerly Fuchs & Partner) takes place worldwide and is a cost-effective and quality-oriented alternative to the previous products on the market.
INDICATOR CARTRIDGE FOR
LINER MATERIALS FOR PIPES AND SHAPES ACCORDING TO THE STANDARD DIN 16965 PART 2 / TUBE TYPE B
DN 25 - DN 1000
Kwerk GmbH now also supplies liner materials for pipes and fittings according to the relevant standard DIN 16965 part 2 / pipe type B.
Our delivery program includes:
- PVC U plasticizer-free polyvinyl chloride according to DIN 8061, color gray
- PVC U plasticizer-free polyvinyl chloride according to DIN 8061, color red
- PVC C nachchloriertes polyvinyl chloride according to DIN 8080
- PE-HD high density polyethylene according to DIN 8075
- PP polypropylene according to DIN 8078
- PVDF polyvinylidene fluoride
Our fittings made of UP-GF are free from defects such as air bubbles and cracks. Over the entire length of the laminate construction according to DIN 16966 is guaranteed.
In principle, other versions in the UP-GF laminate construction can be agreed on request. All sealing surfaces and seams are provided with a laminate layer during production with UP-GF.
PIPES, FITTINGS AND CONNECTIONS MADE OF GLASS FIBRE REINFORCED POLYESTER RESINS (UP-GF)
Y-STRAINERS MADE OF PVC U, PP AND PVDF
DN 65 - DN 500
The recently designed Y-strainers made of PVC U, PP and PVDF, are manufactured in our specialist workshop from qualified personnel for chemistry and process engineering.
Y-strainers with the indicated nominal sizes find application in wastewater- chemical- and process engineering. The strong dirt-holding capacity offers significant advantages to the operator, compared with other versions on the market.
On request, we would be pleased to submit you a detailed quotation for the above mentioned items.
POT STRAINERS MADE OF PVC U, PP AND PVDF
DN 65 - DN 300
Our new pot strainers made of PVC U, PP and PVDF, meet all operational requirements for use in the chemical industry. Other than the simple angle seat strainers, our new pot strainers have high dirt-holding capacities, which increases the lifetimes in plants of the chemical industry and process engineering.
On request, we can equip in our workshop these strainers with measuring instruments, in order to control the procedural steps.
With pleasure, the Kwerk GmbH team will submit a quotation.
PVC TRANSPARENT BALL VALVES
d 20 - d 63 mm according to DIN standards and in INCH dimensions
Together with our partner, we conceive and develop PVC U transparent 2/2-way ball valves for the water technology.
The 2-way ball valve is equipped with screw connection and gluing sleeve and is on request also available with internal threads made of PVC U grey.
Housing, inserts and union nuts are made of PVC U transparent, the valve seat of PTFE, the O-rings optionally of EPDM or FPM and the locking lever of ABS.
The ball valve can be operated with a working pressure of max. 10 bar, at a temperature of 20°C. When using the valve, please mind always the pressure and temperature diagram for PVC U transparent.
With pleasure we will respond to appropriate inquiries.
LOOSE AND COLLAR FLANGES FOR PRESSURELESS APPLICATIONS
MADE OF PVC U, PVC U TRANSPARENT, PE and PP
On a recently designed sheet milling machine we process customized round and square plastic flanges for pressureless applications. Beyond that we produce other items according to customer specifications. The advantage of parts, milled from the solid, is obvious, because of their mechanical strength. They have a favourable price and can quickly and precisely be produced with modern CAD and CNC technology.
On request, we would be pleased to send you a quotation.
DIAPHRAGM VALVES IN BLOCK CONSTRUCTION
SERIES KW BL-ME
In our ultra-modern manufacturing plant, we produce on 5 axis CNC machines customized multi-port valves with diaphragm valves in block construction. The drives are availble as pneumatic version in NC and NO and are compatible with manual drives. You as user will benefit from many advantages and enormous cost savings.
The shown "distributors" are examples for various possibilities and will be manufactured custom-designed in PVCU, PVCC, PE, PP, PVDF and other special materials.
Pneumatic drives feature the following:
- 2/2-way diaphragm valve with pneumatic actuator and optical position indication
- Function: normally closed NC or optionally NO
- Membrane material: optionally EPDM - FPM - PTFE/EPDM
- Control pressure: 4 - 7 bar
- Control connection: R 1/4’
- Control connection in flow direction: upon request
- Drive colour: black
- Membrane: optionally EPDM - FPM - PTFE/EPDM
- Including adjustable closing limit
- Operating pressure: PN 6, unidirectional
On request, we will be pleased to send you our detailed quotation, if desired, also for other variants.
