1 SANITARY Sanitary regulators are engineered for pressure control in sanitary, or clean environments. The applications include pharmaceutical, biotechnology, food and beverage, cosmetics, chemical and other industries where sanitary process control is required for steam, gases, and liquids such as water-forinjection (WFI) systems. Given the environment in which the regulator operates, special consideration has to be given to the regulator s construction and body materials.

2 Application: Sanitary Solutions Introduction There are two common applications for sanitary regulators in pharmaceutical and biotech facilities. They are clean steam and Water-for-Injection (WFI) systems. A common application for clean steam is sterilization. A regulator is commonly used to control the pressure of the steam and thereby maintaining a steady sterile temperature in the system. Regulator set points are typically in the range of 20 to 25 psig (1,4 to 1,7 bar). At these pressures the steam maintains a sterile environment. Providing more flow and less droop allows the regulator to maintain the desired pressure over the range flow. Features Designed exclusively for use in clean/sterile environments Superior flow performance and accuracy Suitable for clean-in-place (CIP) and sanitize-in-place (SIP) systems Self-draining design Tri-clamp end connections Designed to meet 3A, ASME BPE, and European Hygienic Equipment Design Group Criteria Water-for-Injection (WFI) systems is one of the most commonly used materials in wet processes. Typically there is a distribution system or loop. Backpressure regulators are used to control the head pressure of the loop and the pressure drop across the pump. The multiple draw-off processes require the regulators to have high rangeability. Temperature Control Points SR8 Page 475 SR5 Page 457 Feed Water In 454

5 Type SR5 Sanitary Pressure Regulator Introduction The Type SR5 regulator is a compact, large capacity, direct-operated pressure reducing regulator. It is designed for use in applications where a sanitary design is essential, such as pharmaceutical, biotech, or food and beverage industries. Units are available with end connections that match with Tri-Clamp sanitary fittings. The Type SR5 is suitable for use in steam, liquid, or gas service.

36 Sanitary Regulators Fisher Types SR5 and SR8: The clean, clear choice for sanitary process control. Now Available in 1/2" to 3" Port Sizes Helps maintain integrity of your process Engineered for precise pressure control in a sanitary environment. Fisher Type SR5 Sanitary Pressure Reducing Regulators and Type SR8 Sanitary Back Pressure Regulators are designed for applications such as the pharmaceutical, biotechnology, food and beverage, consumer products, cosmetics, chemical and other industries where sanitary process control is required for steam, gases and liquids. Fisher Sanitary Regulators offer several major features and benefits: Designed exclusively for use in clean/sterile environments. Suitable for clean-in-place (CIP) and sanitize-in-place (SIP) systems. Suitable for water-for-injection (WFI) systems. Self-draining design. Standard Tri-Clamp end connections (available with various DIN & ISO connections upon request.) PEEK soft seat option for ANSI Class VI shutoff at temperatures up to 400 F. Construction materials enhance purity of plant products and environment. Each Fisher Sanitary Regulator has a 316L stainless steel body, wetted metal parts and a 316 stainless steel spring case. All wetted surfaces are mechanically polished to a 20 Ra Microinch finish and then electropolished. Diaphragms are available in 316L stainless steel, FKM with a PTFE coating or EPDM. Metal or soft seats are available. The traditional quality and robust construction of Fisher products help to extend the useful life of your equipment and to increase the integrity of your process control system. Designed to meet 3A, ASME BPE, and European Hygienic Equipment Design Group Criteria.
