Forged steel ball valve refers to various forgings and forgings produced by forging methods. The quality of forged steel ball valve is higher than that of cast steel ball valve, it can withstand large impact force, and its plasticity, toughness and other mechanical properties are also higher than that of cast steel parts, so all important machine parts should use forged steel parts.…

The working principle of the forged steel ball valve is to make the valve unblocked or blocked by rotating the valve stem.…

The three-piece forged steel ball valve divides the valve body into three parts along a cross-section perpendicular to the axis of the valve passage with two valve seats, and the whole valve is symmetrical along the central axis of the valve stem.…

The flat gate valve has two floating valve seats. Each seat is designed to be sealed when the medium flows in both directions.…

Expansion type double gate plate gate valve is suitable for chemical, petroleum, natural gas, power plant, coal mine, construction, steel, light industry and sewage treatment industries.…

A parallel single-gate gate valve without diversion holes. The valve adopts the valve seat to float downstream, the spring preloads the automatic sealing structure, the opening and closing force is small, the higher the working pressure, the better the sealing performance.…

Axial-flow check valve should have a streamline shape on the surface of the inner cavity of the valve body, the diversion cover, the valve flap and other flow surfaces, with a rounded front and a sharp back.…

Explosion-proof electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. The valve is divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic.…
