Danfoss Flomatic Corp. has introduced additions to the growing Flo-Flex(TM) family of their rubber disc swing check valves. Suitable for water and wastewater industry, the new Model 745BF features a back flush device used to manually operate the valve in the field. The flange to flange lay length is according to ANSI/AWWA C508-01. Common applications for this would be back flushing, system testing, priming of the pump, draining the lines and system testing. The other addition is their new Model 745PI which provides a valve disc position indicator that gives a distinct indication of the disc position during operation in the field. This swing check valve features a 45° seat with a steel/ductile iron valve reinforced rubber disc. The Ductile Iron 125# flanged body is fusion epoxy coated and can be used as pipeline cleanout. The Danfoss Flomatic Model 745 has a disc stroke of 35° to minimize disc slam, low head losses, and a long rubber disc life. It can be installed in a horizontal or vertical orientation.
