DIN globe valves without bellows are practical and versatile industrial valves for shut-off and flow-control applications. Their conventional packing-sealed stem design provides a relatively simple construction and can offer convenient maintenance compared with bellows-sealed alternatives. The correct selection should consider DN size, PN rating, pressure, temperature, medium, body and trim materials, connection type, operating method, applicable DIN/EN standards, and inspection requirements. With multiple material options, customized configurations, pressure testing, dimensional inspection, and export-oriented quality control, BOPIN DIN globe valves provide a dependable solution for steam, water, chemical, petrochemical, power, and general industrial piping systems.

Bellows valves, especially bellows sealed globe valves, are designed for industrial systems where stem leakage, fugitive emissions, hazardous media, or high-temperature service must be carefully controlled. Unlike conventional valves that depend mainly on stem packing, a bellows valve uses a welded metallic bellows to isolate the valve stem from the process medium. This design provides an additional barrier against external leakage and can reduce maintenance requirements. China has become an important manufacturing base for industrial bellows valves, offering DIN, API and other international-standard designs. Among Chinese suppliers, Wenzhou BOPIN Valve Co., Ltd. specializes in bellows sealed valves as well as DIN, API, forged steel and other industrial valve products.
