Castflow Valves is a valve manufacturer that specializes in check valves. Our range of manufacturing includes Ball Check, Dual Plate, Silent Check and Foot Valves, and covers DN25 (1”) to DN1500 (60”) PN10-100 ANSI150-600# wafer/flanged/lug style. Valves can be cast in different materials, including iron, stainless and super-duplex steel, and other special, exotic alloys. 

Our company has been involved in many of the most important desalination projects globally. At Castflow Valves, we assist with technical support to select the valves and materials that provide the best fitWe are a leading supplier to important equipment builders that have relied for many years on our professional collaboration and quality.  

Castflow has developed new, improved rubber-lined check valves for applications with abrasive and corrosive fluids. The complete 1-piece rubber-lined valve does not contain glued rubber. It guarantees a uniform rubber thickness which fully covers the metal surface in contact with the fluid. In addition, our rubber-lined ball check valves are unique in the wastewater market for applications with fluid containing sludge, solids, etc. Stainless steel or super-duplex ball check valves are additional options for corrosive applications.  

Castflow continuously develops new products depending on the demands of the market. We develop check valves if customers and Castflow have mutual interests. This leads to a close collaboration with our customers.
