Our new product pneumatic valve is based on advanced foreign technology, which has
a special design and matched with electric valve localizer. The valve will work
if entering 4 - 20mADC single and 0.4 - 0.7MPa air supply to realize to control
flux, temperature, and liquid level. The compressed air as its power, the stem
run with core (90°) in the body will realize the full close action. The seal
can be divided into two types that are mental seal and soft seal. This device
has small voltage, close structure, stable running, good seal, easy maintenance
and installation. It specially fit for sticky, contain granule and fiber medium
which are widely applied in oil, chemical industry, teaching facility, light industry,
high pressure facility, paper making and industrial automatic control systems.
