  • Duplex Stainless Steel Check Valve
    Duplex Stainless Steel Check Valve

    The "Duplex stainless steels" are a family of stainless steels. These are called duplex (or austenitic-ferritic) grades because their metallurgical structure consists of two phases, austenite (face-centered cubic lattice) and ferrite (body centered cubic lattice) in roughly equal proportions. Generally a small amount is not less than 30%. Due to the presence of ferrite and austenite in the duplex stainless steel. Therefore, it has the advantages of higher strength of ferritic stainless steel, resistance to chloride stress corrosion, and excellent toughness of austenitic stainless steel. Duplex stainless steel is more resistant to corrosion than the most common stainless steel valves, CF8 and CF8M. Duplex stainless steel valves are widely used in various industries such as chemical industry, seawater desalination, shipbuilding industry, petrochemical industry, oil and gas because of their extremely corrosion resistance and high strength.

  • Dual Plate By Pass Type Check Valve
    Dual Plate By Pass Type Check Valve
    TC2

    By-pass valves are generally used for three basic reasons: To allow the pipeline differential pressure to be balanced, lowering the torque requirement of the valve and permit one-man operation. With the pump closed and the by-pass open, a continual flow is allowed, avoiding possible stagnation. Delayed filling of pipelines. The bypass valve produced by TVCCL is a dual plate wafer type check valve with a hand-wheel to adjust the water flow and achieve dredge effect. It is very simple to use the hand-wheel to control valve to open and close. The installation method is the same as the dual plate wafer type check valve. The only difference is the hand-wheel. The advantage of using the hand-wheel to control the pressure difference is that without external power, and the pressure of the system itself is actuated, which effectively improves the operational safety and more reliable than the conventional electric control valve. Also, the price of the bypass valve is lower than the electric control valve.
