MATERIALS:
Carbon Steel(An iron-carbon alloy with high strength and hardness.It has good mechanical properties and processing properties, and is easy to weld and cut.)
Stainless Steel(A high alloy steel with excellent corrosion resistance.It contains high chromium and nickel elements, can effectively resist oxidation, corrosion and high temperature.)
Low-Temperature Carbon Steel (It has the ability to maintain high strength and toughness at very low temperatures.It is specially treated to work in a low temperature environment from -46°C to -196°C.)
Duplex(Duplex stainless steel has two structural phases, austenite and ferrite, with high strength and excellent corrosion resistance.)
Super Duplex(Super duplex stainless steel has higher chromium, molybdenum and nitrogen content, further improving corrosion resistance and strength.)

FAQ
Q: What are the differences between side entry ball valve and top entry ball valve?
A: 1. Installment Side entry ball valve：Ball is installed from the side of the valve body, which is resulting in a more compact structure. Consequently , maintenance for side-entry one requires disassembling the valve body or the pipeline. Our suggestion is that it suitable for scenarios with low maintenance frequency. Top entry ball valve：The ball is installed from the top of the valve body. During maintenance,we need to remove the top valve cover to replace ball or valve seat, without the need to dismantle the pipeline. 2. Cost Side entry ball valve：Because the ball will be installed from side of body, the body is usally integral structure. The price is more economical. Top entry ball valve：The structure for its body is usually split and the cost is higher than side-entry one,but this kind of valve is easy to maintain. 3. Sealing performance Side entry ball valve：The flow resistance is relatively low, the structure is simple, but the sealing surface is easily affected by the medium erosion. Top entry ball valve：The sealing performance is better. Some models adopt a spring pre-tightening design, which can automatically compensate for wear.
