Product Description
 Globe valve is closed (valve flap) by the valve stem and the central axis along the valve to do the lifting movements of the valve, the pipeline is mainly used to connect or cut off the medium in the pipeline, but can not do with the throttle. 
 
 Basic structural features

1, plastic lining J41 straight through, J45 straight slip, J44 angle valve, with a compact structure, opening and closing flexible, corrosion resistance, short stroke (generally nominal pass through 1/4) and so on. Is widely used in petroleum, chemical and other piping systems to do truncated media, but the plastic lining of the globe valve is strictly prohibited for flow control, so as to avoid throttling at high-speed media flow erosion damage sealing surface.

2, the valve flap and stem design as a whole structure, to prevent the pipeline due to pressure fluctuations caused by the possibility of internal parts out of the body, compact structure, the use of safety.
