Top entry ball valve specializes in the research and development of imported solenoid valves, imported pneumatic valves, imported electric valves and imported traps and other imported valve products production and manufacturing.
TQ41F spring return ball valve is also called spring auto return ball valve, spring auto close ball valve, spring auto reset ball valve, spring auto return ball valve, spring auto return ball valve, etc.
DBB ball valve (Double Block and Bleed Ball Valve) stem adopts the inverted seal structure with sealing gasket set in the lower type, the sealing force of inverted seal increases with the increase of medium pressure in the valve cavity, so as to ensure the sealing effect of the stem.
metal seated floating ball valve Q347Y type PN16~PN64 fixed ball valve for Class150~Class1500, PN16~PN64, JIS10K~JIS20K of various pipelines, used to cut off or connect the medium in the pipeline
cryogenic extension ball valve Q641F, Q641Y type PN16~PN64 pneumatic ball valve: pneumatic, flange connection, floating ball straight-through structure form, seat sealing surface material PTFE, reinforced PTFE plastic (Q641F), metal overlay cobalt base (Q641Y), nominal pressure PN16~PN63, body material WCB, CF8, CF8M, alloy steel ball valve.
3 way flanged ball valve has T and L shape, T shape can make three orthogonal pipeline interconnection and cut off the third channel, play the role of diversion, combined flow, L shape can only connect two orthogonal pipeline, can not keep the third pipeline interconnection, only play the role of distribution.
