KOSO 500R Acid Resistant Type Globe Valves

KOSO 500R Acid Resistant Type Globe Valves provide globe-type control valves for controlling corrosive and poisonous fluids. KOSO 500R Acid Resistant Type Globe Valves Body wetted parts are made of pure Teflon and gland parts are completely sealed by bellows seal bonnet made of pure Teflon. KOSO 500R Acid Resistant Type Globe Valves Body is covered by cast iron or stainless body cover which is resistant to shock from outside.

Product Features

KOSO 500R Acid Resistant Type Globe Valves are plug-shaped discs that are sealed on a flat or conical surface and move in a straight line along the centerline of the valve seat. The movement form of the valve stem also has a lifting rotary rod type that can be used to control the flow of air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media, and other types of fluid. Therefore, this type of stop globe valve is very suitable for cutting off or regulating and throttling. Because the valve stem open or close travel is relatively short, and has a very reliable cut-off function, and because the change of the valve seat opening and the stroke of the valve disc into direct proportion, is very suitable for the flow regulation.

Valve plays a cut off in its line in the medium and the important role of throttle, cut-off valve, as a kind of extremely important truncated class valves, which exert torque on the valve stem seal, valve stem in the axial direction to the pressure on the disc, the valve sealing surface and the valve seat sealing surface fit closely, prevent leakage of the medium along with the gaps between the sealing surface. The sealing pair of the globe valve is composed of the sealing face of the valve disc and the sealing face of the valve seat. The stem drives the valve disc to move vertically along the centerline of the valve seat. In the process of opening and closing the globe valve, the opening height is small, it is easy to adjust the flow, and it is convenient to manufacture and maintain, and the pressure is applicable to a wide range.
