Hanno Valve is a professional China cast carbon steel gate valves manufacturers and suppliers. We have been specialized in carbon steel gate valves more than 25 years. Our valves have a good price advantage and cover most of the European markets. We look forward to becoming your long-term partner in China.

The structure design of Hanno Valve’s Cast Steel Wedge Gate Valves is reasonable, the valve rigidity is good, the flow pass is smooth, the flow coefficient is small.

The sealing surface of Cast Steel Gate Valves is specially treated, such as iron-based alloy surfacing or cobalt-based cemented carbide surfacing, which has the characteristics of wear-resisting, high-temperature resistance and corrosion resistance to ensure a good sealing effect and extend the service life of the Gate Valves.

Hanno Valve Steel Gate Valves are suitable for a variety of working conditions, including petroleum, chemical, pharmaceutical, fertilizer, power and other industries, suitable for cutting off or connecting pipeline media, but can not be used for regulating and throttling. The structure design of Gate Valves is reasonable, the opening and closing is less labor, the medium flow is not restricted, the flow is not disturbed, the pressure is not reduced, the operation is relatively easy.

Hanno Valve Low Temperature Gate Valves are made of stainless steel, nickel-based alloy and other special low-temperature resistant materials to ensure that there will be no embrittlement or fracture at very low temperature, and have good low temperature performance and corrosion resistance.

Hanno Valve High Temperature Gate Valves‌ are made of high quality heat-resistant steel, stainless steel and other materials, which can maintain good strength and corrosion resistance in high temperature environment.The main material of the Gate Valve are WC6, WC9, C5, 20Cr5Mo, 15CrMo, 20CrMo, stainless steel, etc.
