DIN Design Bellows Seal Globe Valve

DIN Bellows seal globe valve is a new kind of globe valves with dual-seal. So its sealing capacity is very good. The sealing surface is bead welding with hard alloy and the stem surface is in “nitrogen treatment”. Hence the valve is attrition resistant, good anti-corrosion and has long service life.
