Rubber flapper check valve is the perfect combination of simplicity, function and design. Developed as a versatile and cost-effective solution to flow reversal, the RF series is based on a low maintenance concept. Its standard ductile iron body and steel-rein-forced Buna-N rubber flapper are produced under the same rigid quality requirements. The 45 degree seat angle also provides a smaller stroke than conventional swing check valves, reducing slamming.
