Usages:
Forms of operation: Manual, worm wheel, electric pneumatic hydraulic ally. These valves can be
used as regulation and throttling units on pipelines and containers with such media as all kinds
of corrosive and incorrosive gases, liquids, semifluid and solid powder in them, which be long
to the pipe system of petroleum, chemical, textile, ship building and matellurgic industries of food,
medicine and paper manufacturers, water and electricity, water supply and drainage and energy
services. These valves can be ficed inany sected position.
We use high quality plywood wooden case packing which avoid fumigation.It have good cushioning performance,
high strength,and corrosion resistance.The use of foam film cover the valve better to protect the valve body and
fixing wooden cases is the final step.
