Seeking valve manufacturers (materials resistant to seawater required)
Thread Content
Hello everyone, does anyone know where valves resistant to seawater are manufactured? Are there ball valves of sizes DN25 and DN15 available in this material as well, for wafer-type butterfly valves DN65 PN1.0? Thank you all! :handshake:handshake
The chloride content in seawater varies; valves used are rubber-lined butterfly valves, nickel-aluminum bronze valves, or duplex steel valves. Butterfly valves are used for large diameters, while ball valves are used for small diameters
Boredo in the United States has a significant volume of business in sea water valves. . . .
Okay, got it. Thank you, friend! :)
The temperature isn’t high, so adhesive sealing is sufficient. The valves recommended by Borei are excellent; they are inexpensive. The set of pneumatic butterfly valves DN80 I supplied to Mamwan Power Plant cost only 2500 in total, which is really cheap.
Marine-resistant alloy cast iron can be used, or ordinary castings with internally vulcanized corrosion-resistant rubber will suffice; for the valve seats and shafts, corrosion-resistant stainless steel is appropriate. The largest size we have manufactured is 2400 with a diameter of 10 kilograms. You can contact 15333832617 to get the design drawings for your reference
Ball valves use F46, while butterfly valve discs are made of duplex steel. @My number is 18761058725. I am a valve manufacturer, and I supply the valves for the seawater desalination project at Hangzhou Water Center
