The most commonly used in the followingconditions:
C12 temperaturerange from 40° to 120°C
HCl, HF, COCl2,VCM, EDC, MDI, TDI, HDI, and other fluid of similar characteristics.
Feature
corrugated pipe
a. The corrugated pipe is hidden in thevalve cover to prevent medium erosion.
b. The multilayer hydraulic formedcorrugated pipe.
c. Service life over 10000 times uses(fully opening to fulling closing).
Stem and packing
a. Additional sealing with gland Metal filler
b. Axial Alignment along the whole strokeof the stem
c. The gland filler depth is more than 2times the stroke, which effectively prevents the contact of chlorine and water.
