RRResilient SeatsCONTROLSEPDM Food Grade seats are standard and perfectly suitable forsanitary applications as well as standard industrial uses.BUNA-N is an excellent general purpose seat material which isparticularly suitable for hydrocarbon service.FKM has improved acid, oil, and temperature resistance overstandard seat materials.POLYURETHANE will withstand severe impact, recover its originalshape after distortion and resist abrasion better than other elastomers.PTFE LINED EPDM seats are usually used where BUNA-Nand EPDM seats are not chemically suitable, especially incorrosive services.VIRGIN PTFE inherent molecular bonding provides optimumprotection against permeation of the line media.CONDUCTIVE PTFE seats combine electrostatic dischargeprotection and the excellent chemical resistance properties of PTFE.UHMWPE provides exceptional chemical resistance, and are theideal choice for highly abrasive chemical applications.Seat material availability depends on valve size & series.
