The check valve is recommended for automatic fire sprinkler systems and is UL/ULC listed and FM approved. The cast iron check valve features flanged end connections for easy installation. The swing check valve includes a renewable rubber disc and bronze seat ring. Swing checks may be installed in horizontal positions (or vertical with flow moving up).
