Sanitary Pressure Regulator
Sanitary Backpressure Regulator
The sanitary regulator / sanitary valve is 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-for-injection (WFI) systems.
Given the environment in which the sanitary regulator / sanitary valve operates, special consideration has to be given to the regulator's construction and body materials. Emerson's line of sanitary regulators / sanitary valve have bodies constructed of 316L stainless steel, diaphragms made of a variety of durable materials, and all wetted parts electropolished to ensure purity in the flowstream.
There are two common applications for sanitary regulators / sanitary valve in pharmaceutical and biotech facilities. They are clean steam and Water-for-Injection (WFI) systems.
A common application for clean steam is sterilization. A sanitary regulator / sanitary valve is commonly used to control the pressure of the steam and thereby maintaining a steady sterile temperature in the system.
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 to the loop and the pressure drop across the pump. The multiple draw-off processes require the sanitary regulators / sanitary valve to have high rangeability.
