DN600 WCB OS&Y Rising Stem Gate Valve
WCB cast steel gate valve is the most common hard seal gate valve, the material is A105, Cast steel has better ductility and higher strength (that is, it is more resistant to pressure). The casting process of cast steel is more controllable and less prone to casting defects such as blisters, bubbles, cracks, etc. .

Stainless Steel Flange Type Floating Ball Valve
The ball valve does not have a fixed shaft, known as floating ball valve. The floating ball valve has two seat seals in the valve body, clamping a ball between them, the ball has a through hole, the diameter of the through hole is equal to the inner diameter of the pipe, called the full diameter ball valve; the diameter of the through hole is slightly smaller than the inner diameter of the pipe, called the reduced diameter ball valve.

Fully WELDED STEEL BALL VALVE
The steel fully welded ball valve is a very common valve, its main feature is that because the ball and the valve body are welded into one piece, the valve is not easy to produce leakage during use. It is mainly composed of valve body, ball, stem, seat, gasket and so on. The stem is connected to the valve handwheel through the ball, and the handwheel is rotated to turn the ball to open and close the valve. Production materials vary according to the use of different environments, media, etc., mainly carbon steel, stainless steel, alloy steel, cast steel, etc.
