Fisher Type SR5 sanitary pressure regulators and Type SR8 sanitary back-pressure regulators

The Fisher Type SR5 sanitary pressure regulators and Type SR8 sanitary back-pressure regulators have expanded to include 2–in. and 3-in. models. In addition to the size expansion, a new PEEK soft seat material has been added. The new material provides ANSI Class VI shutoff in higher-temperature applications (up to 400ºF) and is FDA approved. USP Class VI grades are also available. Furthermore, a 75–125-psig spring size has been added to the SR8 line for 1/2-in. to 1-1/2-in. regulators, raising the maximum setpoint for these products from 100 to 125 psig. The Type SR5 and Type SR8 are designed for optimal performance in water-for-injection (WFI) and continuous clean-steam applications, which include clean-in-place (CIP) and sanitize-in-place (SIP) systems.
