Duplex Stainless Steel Gate Valves Kits

Gate valve is a linear type on/off valve, but the ball valve is a rotary type on/off valve. For soft seated ball valves, size from 1/2" to 4", the MOQ is 6 pieces. In this situation, if the outlet pressure is higher than inlet pressure, the valve will be closed to preventing fluid back-flow. They provide excellent hydrodynamic properties that result in very low-pressure losses and they are technically efficient. Contact us to find out more details. The principle of the check valve is working on differential pressure, it means the check valve only opens if the inlet pressure is over the outlet pressure. Duplex alloys are in a class with several other materials for various types of corrosion resistance. DIN Ball Valves with Bare Stem, Top Flanges and SS304 Brackets. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. The high chromium content of Duplex stainless steel that protects against corrosion, causes embrittlement at temperatures over about 300°C.

When the valve is fully opened, the sealing surface suffered small friction from the working medium. Axial flow structure and accurate flowing passage enables little pressure loss, stable medium flowing, and non cavitation erosion. Acid and alkali corrosion resistance. Optional 30°, 60°, and 90° V-Port ball for regulating the flow. It is widely used in petroleum, natural gas, chemical, marine and other oduct specifications. We take customer demand as the guide, technical service as the center, and customer satisfaction as the goal to comprehensively improve the strength of our company in the field of Super Duplex Stainless Steel Gate Valves. Type 410 is made for working with a variety of liquid and gaseous substances because of its hardness and corrosion-resistant composition. It not only has austenite plus ferrite bidirectional structure, but also saves Ni alloy. Duplex stainless steel is a stainless steel in which the ferrite phase and the austenite phase each account for half of its solid-quenched structure, and the minimum phase content is generally 30%.

Valwell is able to offer Super Duplex ball valves to meet customers' needs, such as ASTM A890 Gr. 1A, 2A, 3A, 4A, 5A, 6A, 1B, 1C. Duplex stainless steel has the advantages of both ferritic stainless steel and austenitic stainless steel: austenitic stainless steel reduces the brittleness, maintains excellent toughness and weldability; ferritic stainless steel improves the yield strength, intergranular corrosion resistance and chloride stress corrosion resistance. Contact Us: Key Specifications / Features. Also, the duplex steel ball valves are particularly resistant to not only chloride stress corrosion but also chloride pitting corrosion.
