J41H - 16 - c national standard globe valve opening and closing is a cylindrical piece of disc, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. National standard globe valve is only applicable to all opened seated, general need not to regulate traffic, customized when allowed to adjust and throttling.

Scope of application:

Flange connection national standard globe valve is suitable for the nominal pressure PN1.6 ~ 16.0 Mpa, the working temperature - 29 ~ 550 ℃ in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as all kinds of working condition of the pipeline, cut off or connect medium. Globe valve applicable medium: water, oil, steam, acid medium, etc. Operation mode: manual, gear drive, electric, pneumatic, etc.

Structure features:

Globe valve products design and manufacture according to the national standard GB12235, rational structure, reliable sealing, excellent performance, beautiful appearance.

Disc and seat sealing surface with iron base alloy welding or department too stand (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good corrosion resistance, abrasion resistance, long service life.

Stem through surface nitriding treatment and conditioning, with good corrosion resistance and abrasion resistance.

Can be used in a variety of pipe flange and flange sealing surface forms, can meet the needs of all kinds of engineering and user requirements.

Pour sealing adopts screw connection seal seat or ontology austenitic stainless steel welding and become, reliable sealing and packing significantly change can be fast and convenient without downtime will not affect the system running.
