MAIN PROPERTIES
BASIC DESIGN
1.Designed
and manufactured according to GB12237-89 or API6D
2.Tested and checked according to ZBJ16006 or API598,
leakage for hard sealing gall valve agrees with the grade of
B.C.D, according to the standard of ISO5208-91, GB/T13927-92
or the agreement between supplier and buyer.
3.Face to Face according to GB12221-89 or ANSIB16.10.
4.Flange according to JB79-59 or ANSIB16.5 or JISB2212.
APPROPRIATE
MEDIUM
Various acids, alkaline,
salt solutions, gaseous media, etc.Hard sealing ball valves
also used in media with particles and fibres.
