Products Details
The WJ41H and WJ41Y steam bellows globe valves, also known as bellows sealed globe valves, are designed with automatic roll welding to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem. The internal structure of the bellows globe valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid from corroding the valve stem. The other end is placed between the valve body and valve cover to form a static seal. Adopting a dual sealing design, if the bellows fails, the valve stem packing will also avoid leakage. The bellows is welded to the valve stem to maintain stable operating performance and avoid valve stem vibration caused by valve plug vibration. More suitable for pipelines with media such as steam, flammable, explosive, heat transfer oil, high-purity, toxic, etc. Suitable for flammable, explosive, highly toxic, toxic fluids, high-temperature heat transfer oil, liquid ammonia and other media with a nominal pressure of PN1.6~16MPa and a working temperature of -29~350 ℃. Widely used in other gas systems such as petrochemicals, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, natural gas, etc., with safe and reliable performance, it is widely used in industrial fluids such as ethylene glycol. The driving methods include manual, gear transmission, electric, pneumatic, etc. The product structure is reasonable, the sealing is reliable, and the double sturdy and durable corrugated pipe sealing design (corrugated pipe+packing) ensures zero leakage of the valve stem. No fluid loss, improving the safety of factory equipment. And comply with international sealing standards. The sealing surface is welded with Co based hard alloy, which is wear-resistant, corrosion-resistant, has good friction resistance, and has a long service life. Valve stem quenching and surface nitriding treatment, with good corrosion resistance and friction resistance; Valve stem lifting position indication, more intuitive.
