Page 7: Presentation
The coaxial design and the electro polished valve interior ensure absolute cleanability and sterilisability. The W9™ valve is 3-A authorised and EHEDG Type EL Class I certified. The American 3-A Sanitary Standard is normative for the component’s ease of cleaning and sterilisation and ensures optimum conditions for food products, which comes in contact with the component in question. - Page 8 30 seconds under the conditions of the test. Abbreviation for Sterilise-In-Place. The process of rendering a process component (like a sampling valve) sterile without removing it from the production line. KEOFITT W9 USER MANUAL V.4 PAGE 8...

Page 11: Sterilisation
NOTE! Furthermore, sterilisation with a chemical sterilant may not convey the same sterility as- surance as sterilisation with steam, because the germicidal and sporicidal kinetics are much less investigated and documented for chemical sterilants compared to steam.

For further information please consult www.keofitt.dk. 3.2 Valve surfaces and roughness certificate All Keofitt valves are electro polished internally using a proprietary technique and each valve has its individual certificate (Test Report) stating the results of 4 test measurements of the surface roughness in each of the 2 ports, in the valve chamber and on the outer body surface with product contact. -
Page 13: Valve Head Configurations
All configurations except the MicroPort options may be delivered with PTFE or FFKM membranes. 3.4 Micro Port option The W9 valve head is available in a version (part no. 600048), where it is possible to take a sample using a long hypodermic needle (part no. 900022). -

Therefore, it is made with a bellow to allow for the valve movement. If you would want to upgrade from Silicone/EPDM to PTFE, it is necessary to contact your local Keofitt dealer or Keofitt directly. -
Page 15: Parts And Accessories
3.8 Parts and Accessories Keofitt provide a huge number of spare parts and accessories to the entire range of sampling valves. These include accessories like: • Barbed fittings and tube welding fittings for tubes and hoses • Adaptors between Tri-clamp, Mini Tri-clamp and Hose Piece (Quick Coupling) •... -

• When steaming always use dry saturated steam without condensation at max. 1 bar(g). At higher pressure the membrane may be damaged/split • Always remember to use safety goggles when steaming, CIPping, taking samples and all other operations of the sampling valve KEOFITT W9 USER MANUAL V.4 PAGE 16... -
Page 17: Everyday Use Of The Valve
Disinfection takes place with the valve closed and involves the following stages of which the first 3 are identical to CIP: Pre-rinse Flushing with water to mechanically remove product residues Clean Applying a detergent to remove remaining visible product residues KEOFITT W9 USER MANUAL V.4 PAGE 17... -
Page 18: Steam Sterilisation
If steaming is the preferred procedure, but no steam is installed near the sampling point, an option is to use a portable steam generator. Keofitt supplies an adapter for a Kärcher steam generator as well as other mobile steam supply systems. The steaming process with a Keofitt sampling valve has been validated to obtain sterility after 1 minute of steaming at 121°... -

Make sure the lock pin has moved fully back to its initial position for a secure locking. IMPORTANT • All illustrations show a sampling valve with Keofitt hose piece connections. All instructions also apply to valve versions with clamp connections; only make sure to use the corresponding fittings. -

6. Rinse through the upper hose piece by squeezing the bottle, thus pressing the water through the valve chamber. 7. Leave the squeezed bottle connected to the hose piece and clamp the hose to avoid contamination from air being sucked in through the valve.

Page 23: Steam Sterilisation
• During sterilisation with steam the valve will become hot and care should thus be taken when operating the valve • The valve is designed for use in working conditions of up to 6-12 bar(g) pressure (depending on KEOFITT W9 USER MANUAL V.4 PAGE 23... -
Page 24: Sampling
For all other sampling use a Keofitt Sterile Sampling Bag or a Spike Bag, which provides a closed flow path for your sample protected against the ambient. Alternatives are bottles with a screw cap, jars or any other available container. - Page 25 Therefore open the valve slowly. Special care must be taken with pneumatically operated valves, as they open abruptly. If problematic, consider adjustable actuators. • Always remember to wear safety goggles when steaming, CIPping, taking samples or any other operations of the sampling valve KEOFITT W9 USER MANUAL V.4 PAGE 25...

Page 32: Mounting Instructions
Remember to disassemble the valve body and head. The valve body and head must be separated during welding. Rubber plugs, chain and membrane must be removed from the valve body, as otherwise heat from the welding process will damage them. KEOFITT W9 USER MANUAL V.4 PAGE 32... -
Page 33: Welding Instructions
W9™ valve welded onto a 2 mm 3” dairy pipe: 50-60 Amp. It should be noted that Keofitt can supply all P type valves welded onto a pipe section according to customer specifications. Flaring is thus avoided and only a girth weld is required. -

• In the rare and unlikely event the neck of the valve body comes loose (gets unscrewed together with the valve head) please contact your dealer or Keofitt to obtain a small tool and instructions of how to reinsert and secure the valve neck. -
Page 39: Replacing A Rubber Membrane
• Don't use a big wrench to tighten the valve head to the valve body. • Don’t clean the valve head in an ultrasonic bath or by immersing it in a degreasing liquid, as it will impede the proper functioning of the screw action. When in doubt, contact your local Keofitt dealer. -
