Non-Rising Stem Globe Valve

Non-Rising Stem Globe Valve, the key component metal bellows, the lower end and the stem components are automatically rolled and welded, the upper end and the connecting plate automatically roll welding, form a metal barrier between the fluid medium and the atmosphere to ensure the zero leakage of the valve stem, the valve is conical design, the seal face and the medium are streamlined, and the sealing performance is better. Longer service life, double seal design (bellows + filling) if bellows failure, valve stem packing will also avoid leakage, and meet international seal standard, dark bar type bellows cut-off valve is fully closed design, can work normally in bad environment, human engineering design handwheel, longer service life, light operation It's easy and safe.
