Products Details

Introduction:

ZJHPF pneumatic film lined with fluorine single seat regulating valve, and fluid contact valve body wall and valve components are high pressure injection molding process, lined with corrosion resistance, aging resistance of polyperfluorinated ethylene propylene (F46), and the use of PTFE bellows seal.Widely applicable to acid, alkali and other strong corrosive media and toxic, volatile gas, liquid control.

Feature:

1, corrosion resistance: almost all the media (including concentrated nitric acid and aqua regia) corrosion.

2, good sealing performance: the use of bellows and packing double seal, to ensure no external leakage.

3, the leakage amount is small: because the spool and valve seat are soft sealed, the leakage amount is low.

4, with HA actuator, large output force, compact structure.
