The Kämmer 191000 Series product line provides control valve solutions for sanitary and aseptic process systems.

In sanitary and aseptic valve applications, the surface finish of all wetted parts is of the utmost importance and need to be free of pits and cracks.

2 The Kämmer Series product line provides control valve solutions for sanitary and aseptic process systems. These valves meet the standards for cleaning in place (CIP) and sanitizing or steam in place (SIP). They are designed to drain freely from inlet to outlet. In sanitary and aseptic valve applications, the surface finish of all wetted parts is of the utmost importance and need to be free of pits and cracks. The Kämmer Series valves meet all of these requirements. The Kämmer Series control valves have a wide range of applications in many industries including food and beverage, biotech, pharmaceutical and others where perfect cleanliness and sterile valves are required. The valves are designed for easy maintenance and all parts in contact with the media are made of corrosion resistant materials including 16 L Stainless Steel, PTFE, TFM or silicon. For the aseptic version of this valve series, a TFM diaphragm seals the media from the environment. The result is a pure aseptic valve design, free from residue or organisms left behind after cleaning thus eliminating any potential source of product contamination. These valves have excellent hygienic properties. The standard surface finish for all series valves is 24 Ra microinch. Optionally, 24 Ra microinch (electropolished) and 16 Ra microinch (electropolished) are avaliable. Flowserve can also provide a better quality surface finish than 16 Ra microinch where required for specific applications. All of these valve designs carry a A approval and conform to USDA standards.

3 Specifications Table 1: Features and Advantages Features Body Connections Aseptic diaphragm Advantages One valve body design utilizes different bonnet options for various sanitary and aseptic applications. All valve bodies are self-draining, pocket free and meet CIP and SIP standards. Because of various end connection options, these valves can be installed in almost every plant. The aseptic diaphragm for the and Series valves is made of a combination of TFM on the media side and EPDM as the base material. The diaphragm material is FDA approved.

4 Type Hygienic, Food and Beverage The type is the prime choice for nearly all applications in the food and beverage industry. Because of it s optimized body design the valve is pocket free so that bacteria or any other kinds of contamination are avoided. The seat is an integral part of the body to avoid additional gaps. The O- Ring packing and general bonnet design ensure a very compact overall height. The stem is guided by a PTFE bushing for precise control, reduced friction and minimal wear. A wiper ring is provided to protect against contamination from the outside. Repair and maintenance are easy to perform because the body / bonnet connection utilizes a tri-clamp. Figure : Type Kämmer series design The type is designed in accordance with A and USDA (United States Department of Agriculture) requirements. Leakage can be very quickly detected by a system of holes drilled into the bonnet and the body. The hole in the bonnet is connected to a circular groove just above the O-Ring. Any media leaking past the O-Ring can flow through the holes to the outside and is readily visible. The hole in the body is situated within the body and bonnet clamp enclosure to prevent the ingress of contamination from the outside. The stem O-Ring is located very close to the lower end of the bonnet to ensure that the gap between the stem and the bonnet is as small as possible.

6 Type / Aseptic Both valve types and were developed for aseptic applications in the pharmaceutical, biotech and other industries with ultra clean valve applications. The diaphragm s base material is EPDM with TFM facing on the media (wetted) side. The diaphragm is used to seal the media from the environment. A diaphragm support ring (anti-shock plate) is installed on the reverse side of the diaphragm. This unique feature significantly extends the life of the diaphragm. The diaphragm has been cycle life tested at 145 psig and 266 degrees Fahrenheit and achieved over 500,000 cycles without failure (Cycle Life data for varying pressure and temperature combinations are available upon request). The diaphragm can be used to temperatures up to 20 degrees Fahrenheit. There are two different styles available for these aseptic valves. Both valve styles utilize the same valve body, aseptic diaphragm and valve plug head but use different bonnets and valve stems. These are explained in Figures 6 and Figure 7. Figure 5: Type Type Aseptic with test port connection The aseptic type valve uses an O-Ring seal on the stem (above the diaphragm) and a 1 / 4 NPTF test port connection for leak detection in case of a diaphragm failure. The outside radius of the aseptic diaphragm is clamped between the body and bonnet and also serves as the body gasket. The valve is equipped with the standard diaphragm support ring. The screwed plug design allows for easy replacement of the aseptic diaphragm or the valve plug, independently from one another.

7 Type Aseptic The does not have a test connection port. Possible leaks are detected in the same way as the standard type sanitary valve, through small holes in the bonnet and body. The hole in the body is situated within the body and bonnet clamp enclosure to prevent the ingress of contamination from the outside. All other features of the aseptic valves including diaphragm support ring and the screwed plug head diaphragm stem connection are standard on the type valve.
