DPW Series

Les clapets anti-retour à double plaque assurent une prévention efficace du reflux avec une faible perte de charge, améliorant ainsi la fiabilité et la sécurité du système dans les applications industrielles à haute pression et à haute température, tout en offrant une grande souplesse de configuration pour les conditions de processus exigeantes.

• 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
