Youfumi fully lined plug valves are cavity-free dueto the special body design, the liner is firmlylocked.
Plug coating is extended over the shaft sealing.
The lining are moulded into dovetail recesses inthe body to lock them in place to prevents linercollapse in vacuum conditions and blow out in highpressure conditions.
Two way cavity free designs prevent accumulationof particulate matter making it an ideal choice forslurry application.
There is ideal taper design for the plug and thebody cavity. When it failures to seal as a result ofworn in using process, the three adjusting bolts inthe cover work for external adjustment of in-lineseal, to assure a maximum sealing capability andan extended service life.
Top sealing components form the second sealing.When the sealing surface failures to work,itprevents medium leaking through the valve stem.
Disassemble the four bolts on the cover, all theparts in valve can be took out,and replace theparts directly without the need to remove valvefrom pipeline.
Lined three-way plug valve is the best choice forcorrosive diverter valve application.
It can sustain any corrosive medium in addition tothe “molten alkali metals and fluorine elements”. Itis ideal products used in chlor-alkali, industrial inorganic chemicals, metal and mining, nitrogen andphosphatic fertilizers,petroleum refining.pharmaceutical etc.
Lining material: PFA, FEP, PO etc.
Operation methods: manual, worm gear, electric,pneumatic and hydraulic actuator.
Youfumi lined plug valves are available as per theneeds of applications in additional sizes and otherthan standard materials.
Our products are sold all over the world, you can rest assured.
