5. e into contact with the component in question The valve is used in a wide range of business areas where sampling is made through an Ingold port DN25MM Warning During sterilisation with steam the valve will become hot and care should thus be taken when handling the valve Restrictions e The valve cannot be used for vacuum since the membrane will be sucked hard into the seat e The membranes are available in three different qualities silicone EPDM and PTFE e The silicone membrane has the advantage that it can in general stand higher temperatures but it cannot tolerate moisture condensation resulting from steam sterilisation e The EPDM membrane is better able to cope with condensation in the steam and at the same time can be used with the majority of CIP fluids e The PTFE membrane resists most CIP fluids and very high steam temperatures 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 witho ut interrupting the production process Sterilisation is carried out by supplying steam through the upper of the valve s two hose pieces It is 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 valve seat and as a hygienic static
