Valves & Actuation

Asahi/America Swing Check Valves are self-contained, automatic valves which are used to prevent the reversal of flow in a pipeline. When open and under flow pressure, the checking mechanism will move freely in the media, offering very little resistance and minimal pressure drop. Asahi/America Swing Check Valves utilize a swinging disc which requires only minimal back pressure to close the valve. This valve can be modified, with lever and weight or spring, to assist in seating faster, and to eliminate shock.

Features -  • Minimum resistance to flow     • May be installed either vertically or horizontally     • Excellent flow characteristics   • Disc seats tightly with minimum back pressure     • Seat materials - EPDM, FKM or PTFE     • All sizes rated for full vacuum service   • PVC valves up to 3” rated for 150 psi @ 80°F, 4" to 6" sizes rated for 100 psi and 8" size rated for 75 psi.

Swing Check Options
• External lever and weight to assist disc in closing quickly     • External spring to assist disc in closing

Asahi/America Type 57 Butterfly Valves disc has about the same diameter as the connecting piping, and the flow is straight through, with a low pressure drop. The solid thermoplastic butterfly valves have a lined body design and bubble-tight seal with only the liner and the disc as wetted parts. Asahi/America Type 57 Butterfly Valves are self-gasketing, eliminating the need for additional flange gaskets. Asahi/America Type 57 standard model has a PVC or PP body with a polypro, CPVC or PVDF disc for better chemical and abrasion resistance at temperatures higher than can be achieved with other PVC butterfly valves. All models standard with 316SS shaft.
