The valves can be used with either pneumatic orelectric valves for food processingSAMSON has a range of valves designed to meet the specific requirements ofthe food Processing industry. This range includes the Type 3345 DiaphragmValve (see T 8031 EN), Type 3347 Hygienic Angle Valve (see T 8097 EN)and Type 3249 Aseptic Angle Valve (see T 8048 EN).

5 The valves can be deliv-ered with common end connections, such as flanges, hygienic couplings,clamp fittings and welding and design are certified to comply with regulations stipulated byFDA, EHEDG, 3A valves for the Pharmaceutical industrySAMSON's Type 3249 Aseptic Angle Valve and the diaphragm valves byour partner SED Flow control GmbH were developed specifically for asepticapplications in the food Processing and Pharmaceutical meet with the stringent FDA and EHEDG requirements, the valve bodies aremade of stainless steel and wetted surfaces are electropolished or machinedto a fine finish. The cavity-free valve bodies are designed for (CIP) cleaning-inplace) or SIP (sterilization-in-place).An EPDM or PTFE diaphragm seals off the valve from the actuator and pre-vents any process medium from escaping to the atmosphere. The diaphragmused in diaphragm valves also functions as the throttling with the hygienic valves, these valves come with end connections designedas detachable or permanent regulatorsIn the food Processing and Pharmaceutical industries, the Type 2371 PressureRegulators are used as excess pressure or pressure reducing cavity-free bodies of the regulators are made of stainless steel and wettedsurfaces are electropolished or machined to a fine set point can be adjusted mechanically or stem of the regulator can be locked in place to keep the plug open for CIPor SIP 3249 Aseptic Angle ValveV2001-IP Globe ValveSED Steripur 407 Aseptic ValveType 2371-00 Pressure Regulator withpneumatic set point adjustment6 Special Valve FeaturesValve bodyThe valves are available in all common and specified alloys.

6 While valves in-tended for controlling the supply of water or steam in plants have bodiesmade of cast iron or cast steel, hygienic or aseptic valves are manufactured instainless steel to satisfy stringent requirements. These valves have bodiesmade from investment castings, forged steel or bar stock to meet specific finishesIn hygienic and, in particular, aseptic applications, the valves must be cleanedor sterilized to meet CIP or SIP requirements. The valves' surface finish must bedesigned to prevent the process medium from sticking to the inside of the valveand to minimize external contamination. The valve surface can be machinedto achieve a surface roughness down to Ra m. The standard roughnessis Ra m or polishingThe required quality of the surface finish is achieved by machining or manu-ally polishing surfaces. Favored methods include glass bead blasting and mechanically polished valve body ( with 400-grit abrasives) is im-mersed in an electrolyte bath and a DC power supply is applied.

7 The electro-chemical process implemented according to a standardized procedure re-moves the peaks from the roughness profile by at least 20 valve body acquires a shiny finish and is less sensitive to medium depos-its. Common terms for electropolished surfaces include satin finish and and throttling elementsParabolic plugParabolic plugs are easy to manufacture and can be cleaned easily. The plugshave a tendency to vibrate as the plug stem is only guided on one type of plug is best suited for on/off applications and used at low pres-sure plugThis special plug design is fairly complicated to manufacture and requiresmore care during V-port plug is guided in the seat to prevent vibration. It is suitable for highpressure use of a diaphragm as a throttling element ensures that the process me-dium does not come into contact with the actuator and cannot escape to theatmosphere.

8 Tested and approved materials, such as EPDM and PTFE, andthe specially designed bodies of samson 's Type 3345 and Type 3249 Valves as well as SED's diaphragm valves guarantee aseptic leakageThe valves are tested according to the standardized procedures and theirmeasured seat leakage is graded in leakage EN 60534-4 is used for DIN valves, whereas ANSI/FCI 70-2 is appliedto ANSI 's diaphragm valves used as shut-off valves have zero seat leakage. Theseat leakage of these valves is tested in accordance with DIN EN polished surfaceElectropolished surface finishParabolic plugV-port plugOne-piece fabric-reinforced diaphragm 7 End connectionsThe end connections connecting the valves to the pipeline are available withdetachable or permanent welding ends. Detachable end connections areavailable as flanges, threaded ends or clamp end connections can be supplied to meet all common pipe standards(ISO, DIN, ASTM, BS, SMS, JIS).

9 The inside diameters of the mating ends mustbe identical to ensure a flush transition between pipe and fitting as well ascomplete or butt weld endsWelding ends provide safe and maintenance-free pipe diameter and material thickness specifications exist for valvesmanufactured for the food Processing and Pharmaceutical industries due tothe wide variety of existing meet hygienic or aseptic requirements, the ends of the butt weld fittings andthe pipeline must be identical. Orbital welding is the most common method toweld on the ends without filler in all DIN versions are used in plant flanges according to DIN 11864-2 Form A are sealed by partiallyopen O-rings. This reduces dead cavities and improves cleanability. Groovedand mated flanges are screwed together and have a metal-to-metal stop, en-suring that the O-ring is mounted with a defined compression.

10 Both flangesare joined to the pipe ends by orbital welding. The weld seams are polished tomeet the finish quality of the valve pipe connectionsThe male part and liner are held together by a coupling gasket is used for sealing in hygienic couplings according to DIN to the aseptic flanges, the aseptic pipe connections are sealed by par-tially open O-rings. A metal-to-metal stop permits the gasket to be com-pressed in a precise and controlled way. The male part and liner are joined tothe pipe ends by orbital welding and polished to meet the finish quality of fittingsThe joints are held together by a cone-shaped clamp. An EPDM or PTFE gas-ket is inserted between the clamp fittings.
