Many years of proven reliable performance in various industries. Concentric design raised centre seat Disc Seat ring Figure shows the OMOE sealing design between the disc and seat. he raised section of the seat reduces and minimises the operating torque while ensuring a tight seal between disc and seat. Figure Body Flange Rounded dove-tail design Figure 2 shows the self-gripping seat ring design firmly in place inside the body. his design ensures the seat cannot be displaced during the bolting up of the adjoining flange. he seat also acts as the gasket between the valve and the pipe flange. riple-sealing system Seat ring Figure 2 Body Flange Figure shows the triple stem seal. he primary seal is created from the initial compression between the flat surface of the seat and the flat hub of the disc. When the valve is subject to normal operating conditions this seals the shaft and body from any contact with the flowing medium. he secondary seal is accomplished by an O-ring fitted into a stainless steel cartridge which is moulded into the seat ring. here is a secondary seal at each end of the stem where it penetrates the seat. he third seal is to prevent dirt and other foreign materials within the environment from getting into any of the working valve parts. hird seal Secondary seal Primary seal Figure Stem Body Seat ring Disc E-0 E// 205.09.2 5
Discs and seats come in various materials to meet a wide range of needs. hese are the ultimate general purpose valves and they provide excellent cost performance. Specifications ype Size Max.
