Wenzhou Wofer Valve Co., Ltd. offers a high-performance DIN Cast Steel Bellows Seal Globe Valve, engineered for absolute zero stem leakage and superior reliability in critical industrial applications. This advanced bellows sealed globe valve features a robust dual-seal design (bellows plus secondary packing), hard alloy bead-welded sealing surfaces, and nitrogen-treated stem for outstanding wear resistance, corrosion protection, and extended service life.
Designed and manufactured in compliance with EN 13709, with face-to-face dimensions per DIN 3202 / EN 558-1, flanged ends to DIN 2543-2545 / EN 1092-1, and rigorously tested according to DIN 3230 / EN 12266, this valve guarantees exceptional sealing performance and safety. The stainless steel bellows (304/316 options) form a hermetic barrier, making it ideal for handling hazardous, toxic, flammable, or high-temperature media where even minor leaks are unacceptable.
