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.

A Flange End Forged Stainless Steel F304 Bellows Sealed Gate Valve is designed for applications requiring reliable isolation, corrosion resistance, and reduced fugitive emissions. By combining a forged stainless steel body, 304 stainless steel construction, flanged connections, and a metal bellows sealing system, this valve provides a robust solution for demanding process piping.

The gate valve uses a linear opening and closing movement. When fully open, the gate is lifted away from the flow passage, providing relatively low pressure loss. When fully closed, the gate contacts the seats to isolate the downstream piping. The bellows assembly provides an additional barrier around the stem, helping prevent process media from escaping through the stem packing area.

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. BOPIN states that its production includes bellows sealed valves and that its products serve oil & gas, steam, water treatment, power generation and chemical processing applications.
