J41H American Standard flange globe valve design and manufacture in accordance with the American National Standard ANSI BI16.34, applicable to ANSI Class 150LB. working temperature -29 ~ +250 ℃ of various pipelines, used to cut off or connect the pipeline medium. J41H American Standard flange globe valve body, bonnet has a good strength, rigidity and flow capacity. The bonnet is designed with upper sealing seat, which makes the packing seal more reliable and convenient for the replacement of packing in the fully open state. Packing, gasket can also be based on the actual working conditions or user requirements reasonable selection, can be applied to a variety of pressures, temperatures and media conditions, reliable sealing. The medium and large caliber set rolling bearings, easy to open and close.
Working Principle
J41H American Standard flange globe valve opening and closing parts are plug-shaped valve flap, the sealing surface is flat or conical, the valve flap along the center line of the fluid for linear movement. Stem movement form, there are lifting stem (stem lift, handwheel does not lift), there are also lifting rotating stem (handwheel and stem with rotating lift, nut on the valve body).
