Delta Pacific Valve Mfg. Co. manufactures dual-plate check valves from size 2” to size 54” in ANSI Class 125 to ANSI Class 2500 pressure ratings.  DPV® dual-plate check valves are weight-saving and intrinsically non-slam, reverse flow prevention devices.  DPV® dual-plate check valves are available in wafer, lug (a.k.a. wafer-lug), and double-flanged body styles.  DPV® dual-plate check valves are available in conventional through-body pin design, or with retainerless body design to reduce the number of body leak paths.  DPV® dual-plate check valves are manufactured to API 594 (Type “A”) standard and to API 6D standard.  Body seating designss are available as metal-to-metal seating and resilient seating, such as Buna-N (a.k.a. NBR), EPDM, and Viton® A elastomers.  Valve body materials include gray cast iron, ductile cast iron (a.k.a. spheroidal graphite cast iron), ASME B16.34 material group 1, group 2, group 3, aluminum-bronze, titanium, and other alloys.  Other materials, configurations, and customer specified special features are available upon request.  Contact us and consult with DPV® to purchase and specify DPV® dual-plate check valves for your dual-plate check valve requirements.  Start reaping the benefits of using DPV® dual-plate check valves at your facility today!
