Keofitt Sampling Valves

The Keofitt sampling valve is a valve which can be readily sterilised and which meets both hygienic and production requirements. This means that an effective cleaning and sterilisation of the sampling valve can be carried out between random samples independently of the course of the production process.

The valve is 3-A authorised. 3-A Sanitary Standards is an American standard which is normative for a component’s ease of cleaning and sterilisation. 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, such as breweries, dairies, and the pharmaceutical and biotechnological industries.

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 is the perfect, hygienic design in the inner part of the valve which enables absolute sterilisation in a closed state.

According to an EHEDG-based test carried out by the Biotechnological Institute in Denmark, the valve is sterilised after just 1 minute’s supply of steam at a pressure of 2 bar (121°C).

Following sterilisation, but prior to sampling, a sterile plug of rubber or stainless steel is fitted to the top hose piece. When the valve is opened the liquid will run out of the hose piece.

Note ! The membrane functions both as a dynamic packing in the valve seat and as a hygienic, static packing against the valve body.

Warning!:
The valve is designed for use in working conditions of up to 6 bar and temperatures of up to 121°C. It is therefore important to be aware that the rubber plug (designed for max. 5 bar) or the steel plug (designed for max. 10 bar) can be forced out at high speed if not seated correctly. Therefore always remember to use safety goggles when taking samples because of the risk to the eyes.

Restrictions:
The valve cannot be used for vacuum since the membrane will be sucked hard into the seat. The membranes are available in two different qualities: silicone and EPDM.

The silicone membrane has the advantage that it can in general stand much higher temperatures, but it cannot tolerate moisture condensation resulting from steam sterilisation.

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. !
