DN150 to DN1200
Duvalco Check Valve Non-Slam design is achieved through a carefully balanced relationship between door weight and angle, providing minimal maintenance and avoiding damage to other pipework components. The absence of weights or dampers minimizes the risk of shaft damage and leakage. All sizes are available with metal seating of the door. Sizes up to DN300 are also available with the door encapsulated in EPDM or NBR
rubber.
