Product Description
J41H flanged globe valves are designed and manufactured to API and ASME standards.Globe valve, also known as cut-off valve, belongs to the forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak.When the medium from the lower part of the disc into the valve, the operation force needed to overcome the resistance is the friction force of the stem and packing and the thrust generated by the pressure of t...
Product structure characteristics
A check valve is an “automatic” valve that is opened for downstream flow and closed for counter-flow.Open the valve by the pressure of the medium in the system, and close the valve when the medium flows backwards.The operation varies with the type of check valve mechanism.The most common types of check valves are swing, lift (plug and ball), butterfly, check, and tilting disc.Products are widely used in petroleum, chemical, pharmaceutical, chemica...
Product Description
The function of the check valve is to prevent the media from flowing backwards in the line.Check valve belongs to automatic valve class, opening and closing parts by the force of the flow medium to open or close.Check valve is only used for medium one-way flow on the pipeline, prevent medium backflow, to prevent accidents.
