DPW Series Dual Disc Metal Hinge Check Valves

DPW Series

The DPW dual plate wafer check valves are designed for high-pressure and extreme-temperature industrial applications, delivering reliable backflow prevention with API-compliant performance. Covering a broad range of pressure classes and sizes, these metal hinge dual disc valves are ideal for demanding process environments including chemical, refining, and power generation. Available in multiple materials and configurations—including retainerless designs for critical service—each valve is engineered for low pressure drop, durability, and seamless interchangeability with industry-standard dimensions.

Le valvole di ritegno a doppio disco garantiscono un’efficace prevenzione del riflusso con una bassa caduta di pressione, migliorando l’affidabilità e la sicurezza dell’impianto in applicazioni industriali ad alta pressione e alta temperatura, consentendo al contempo una configurazione flessibile per condizioni di processo particolarmente impegnative.

  • API 594 compliant and API 598 tested to ensure industry-standard performance and interchangeability
  • DPW: Classes 125–150 (2"–20") for broad application coverage
  • Wide operating temperature ranges: DPW from -70°F to 500°F depending on seal
  • Dual plate, metal hinge design delivers reliable backflow prevention with low cracking pressure (0.098–0.241 psi)
  • Low-pressure-drop performance with high Cv range (up to 38,000) for efficient system flow
  • Material options including cast iron, carbon steel (WCB), and 316 stainless steel for demanding environments
  • Multiple seal and spring options (metal, Viton, EPDM, PTFE, Inconel, 316SS) to match temperature and service conditions
  • Standard or retainer less body design enhances safety for critical hydrocarbon and chemical applications
  • Compact, lightweight wafer design enables easy installation while reducing cost and system load
  • Engineered to reduce water hammer and improve overall system reliability and longevity
