Internal Feature
Indicator of Valve Location
Protecting cover, which can separate internal stem from outside,
has the function of indicating valve location.
Double sealing structure of O-ring & PTFE gasket
Prevent the inflow of fume from the outside. remove the heterogeneity and clearence while handling
The smooth contoured body
has minimal pockets, cavities or dead space,which prevent accumulation or stagnation of precess fluids or contaminants
Double sealing structure of O-ring & PTFE gasket

Improvement in the intensity illumination and the transparency of PFA lining
With different material, the difference of curve strength and coefficient of elasticity would diminish its sealing function. Diaphragm composed by rubber and PTFE can enhance the sealing function of a valve.
Normally-open and normally-closed valves are designed individually.If normally-opened control valves are used in a normally-closed line,leackage may occur due to the accumulation of fatigue loading.
The flow area of the gate is greater than the pipe head, which prevents pipeline pressure loss
and and pump overload.
