Page 7: Presentation
1. PRESENTATION The Keofitt SESAME sampling valve is an enhancement of the renowned classic W9 sampling valve taking representative and uncompromised sampling to new heights. SESAME is a dual function valve individually controlling both the cleaning (steaming or liquid detergent/ disinfectant) process and the sampling action through a single turn knob. - Page 8 Complexing agent A substance capable of forming a complex compound with another material in solution. Improves the cleaning properties of a detergent. Contact time The time span during which the item is in contact with the detergent or the disinfectant. Enzymes Molecules, which are added to cleaning agents to ease the removal of specific organic material.

Page 9: Quick Start
Spores Relatively water-poor resting cells surrounded by an impervious cell wall, which makes them relatively resistant to disinfectants and sterilants. They are dangerous as they can survive in adverse conditions and re-emerge as live bacteria at a later stage. Sporicidal The property of an agent that kills spores. -

2. CLEANING – DISINFECTION – STERILISATION 2.1 Clean-In-Place (CIP) Thorough cleaning of the valve is a prerequisite for proper disinfection or sterilisation. Cleaning of the valve is the removal of any visible residual product, it be organic or inorganic. It may be done using either steam (continuous steam will eventually lead to sterility;... -

3.9 Valve cleaning /disinfection /sterilisation The table below describes the two fundamentally different ways of preparing the valve for sampling, 1) Chemical cleaning/disinfection and 2) Steaming: Method Description Pros & Cons Chemical Liquid detergents are used to clean the This process is adopted where steam cleaning valve. -
Page 17: Everyday Use Of The Valve
4. EVERYDAY USE OF THE VALVE This chapter gives an introduction to how the sampling valve works in different operating conditions. conditions, such as the cleaning of the entire production line before starting a new batch (chapter 4.1) and the cleaning of the valve between each sample during the batch production (chapters 4.2-4.4) For specific operator instructions please refer to the chapter “VALVE OPERATIONS”. -
Page 18: Chemical Disinfection
Keofitt supplies fittings for a Kärcher steam generator. The steaming process with a Keofitt sampling valve has been validated to obtain sterility after 1 minute of steaming at 121° C (1 bar(g)). Documentation is available at the Keofitt Online Service Center on www.keofitt.dk. -
Page 19: Valve Operations
For the initial cleaning before a new batch please refer to chapter 4.1 Batch change cleaning. 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. -
Page 20: Chemical Disinfection
6. Reconnect the water hose to the upper hose piece and rinse with clean water by turning the knob towards “Clean”. If disinfection is not needed the valve is now ready for taking a sample. If disinfection is required proceed with the steps mentioned in the section “Chemical disinfection”... - Page 21 5. Disconnect the hose from the INLET hose piece and connect a flexible bottle with cleaned water to the INLET hose piece. 6. Set the valve in its “Clean” position and rinse through the INLET hose piece by squeezing the bottle, thus pressing the water through the valve chamber.
-
Page 22: Steam Sterilisation
6. Connect a flexible bottle with cleaned water to the INLET hose piece, set the valve in its “Clean” position and rinse through the upper hose piece. 7. Set the valve in its “Off” position and either remove the squeezed bottle or leave in place as an additional protection against the environment. - Page 23 2. Connect a hose to the OUTLET hose piece and let it go to drain. NB: Do not connect a steam trap as it will impede the flow of steam and thus the flushing effect. 3. Open the steam supply and let it flow through the valve for sterilisation.

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 protecting it from the ambient. Alternatives are bottles with a screw cap, jars or any other available container. -
Page 25: Technical Data
A 6-digit code is marked on the valve body. This code refers to a 3.1 certificate which accompanies every consignment of valve bodies. The 3.1 certificate is available at the Keofitt Online Service Center on www.keofitt.dk. Click Certificates and then 3.1. -
Page 26: Surface Finish
A serial number identifies each valve body. A specific surface roughness certificate is supplied with every valve. A general surface finish certificate copy is available on www.keofitt.dk 6.6 Viscosity: Viscosity range: 0-1000cP, with particles up to 3mm in diameter. - Page 27 The generally accepted sampling time is around 10 sec. for small samples and around 30 sec. for larger samples. As usual sample sizes are between 100 ml and 1000 ml the needed flow lies from 600 to 2000 ml/min. As the pressure on the sample side usually is 0 bar(g) the pressure drop across the valve equals the process pressure (tank pressure or line pressure).

Page 35: Maintenance
13. MAINTENANCE 13.1 Maintainance The EPDM and Silicon membranes should be replaced every other month. PTFE and FFKM membranes should be replaced every 12 months. In the event of intensive sterilisation and cleaning it may be necessary to replace it more frequently. The appropriate replacement frequency should be determined by the user by starting with short intervals and continuously extend the time in use until one reaches the limit of the membrane’s durability. -
Page 36: Disassembly And Assembly Of Valve Body And Head
Omitting to do so may cause damage to the membrane. • 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. -
Page 37: Instructions On Replacing A Ptfe Membrane
To attach a new membrane to the valve head: Set the valve head to “Sample” position. Place the new membrane on valve head and press the new membrane against the steel shoulder in order to allow the membrane to lock into the groove. Set the valve head in its “Clean”... -

Page 39: Failure Modes
14. FAILURE MODES If the membrane is not replaced with a new one at regular intervals (depending on the application), it may eventually break, usually around the tip and more seldom along the side or at the integrated o-ring. 14.1 Broken membrane tip: This failure usually causes product to leak from the process side and more or less product will flow out through the lower port, also when the valve is in closed position. -
