Stainless steel Globe valve

Product features:
(1) simple structure than the Gate Valve, manufacturing and maintenance are more convenient.
(2) sealing surface easy to wear and abrasion, good sealing, no relative sliding between Valve clack and body sealing surface when opening and closing, and thus wear and scratches are not serious, good sealing performance, long service life.
(3) when opening and closing, Valve clack stroke is small, thus Globe valve height smaller than Gate Valve, but Length of structure than the Gate Valve long.
(4) opening and closing torque, the headstock more effort, opening and closing time principal.
(5) flow resistance, because more tortuous path within the body medium, large fluid resistance, power consumption.
(6) flow direction of medium Nominal pressure PN≤16MPa, generally used downstream, upstream from the medium Valve clack direction; when Nominal pressure PN≥20MPa, generally countercurrent, media orientation downstream from the Valve clack. To increase the use of the seal can, Globe valve medium can only flow in one direction, you can not change the direction of flow.
(7) fully open Valve clack often affected by erosion

Application Specifications:
1, Design and manufacture according to GB12235-89
2, Length of structure according to GB12221-89
3, flange Size JB / G79-94
4, Valve inspection and testing according to GB13927
