  • Design and Selection of Check Valves Val Matic

    Design and Selection of Check Valves 3 Nozzle Check Valve Silent Check Valve categories of check valves, Lift, Swing, and Dashpot‐Assisted are each designed with unique features for specific applications and each contribute differently to the system response and costs There is no “universal” check valve for all applicationsDESIGN FEATURES J&S HedFlex Check Valves are constructed with superior high grade rubber and superior polyester reinforcement to improve performance, operation, and life expectancy There are many grades of rubber that vary in chemical makeup The elastomer’s chemical makeup “the recipe“ determines cost, characteristics, durometer (hardness and stiffness), and quality of the rubberDUCKBILL CHECK VALVE jandsvalveDESIGN FEATURES Ball check rubber lined with anti abrasive rubbers for mining industries application The rubber lined dual plate check valves are a cheaper alternative to other alloyed materials which are resistant to corrosive applications Available in several types of rubber Castflow valves is producing the dual plate check valve with the same system that applies the butterfly valve withRubber CASTFLOW VALVES – Check Valves Manufacturer
