6. n The standard ensures optimum conditions for food products which may come into contact with the component in question The valve is used in a wide range of business areas where sampling high viscosity products such as dairies yogurt fruit and marmalade industries Warning During sterilisation with steam the valve will become hot and care should thus be taken when handling the valve Restrictions The valve cannot be used for vacuum since the membrane will be sucked hard into the seat The W15 and W25 valves are only available with PTFE membranes The PTFE membrane resists most CIP fluids and very high steam temperatures W15 is only available with Clamp on the inlet outlet connections For best results it is best to leave the steam hose constantly connected to the valve Detaching the hose risks air contamination and makes the sterilisation process unnecessarily complicated Valve function The valve is designed to regularly take representative random samples in the production process The valve is therefore designed such that effective cleaning sterilisation and sampling can be carried out regularly without interrupting the production process Sterilisation is carried out by supplying steam through the upper of the valve s two hose pieces It 1s the perfect hygienic design in the inner part of the valve which enables absolute sterilisation in a closed state Note The membrane functions both as a dynamic packing in the val
