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. 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.

The API 609 cast steel A216 WCB butt-welding-end multi-level sealing triple-offset butterfly valve is an excellent solution for demanding isolation applications where compact construction, high-temperature capability, low seat wear and reliable sealing are required. Its combination of triple-offset geometry, multi-level sealing, metal seating, A216 WCB construction and butt-welding ends provides a robust alternative to conventional flanged butterfly valves and, in appropriate services, can offer significant advantages in pipeline integrity and maintenance. 

The die forged stainless steel F304 handle operated flange end floating type PTFE sealed ball valve is a reliable quarter-turn valve designed for demanding industrial applications where corrosion resistance, tight shut-off, mechanical strength, and dependable operation are essential. Manufactured from forged ASTM A182 F304 stainless steel, this ball valve combines the strength and structural integrity of a die-forged body with the excellent chemical resistance of austenitic stainless steel. Its floating ball design and PTFE sealing system provide efficient flow control and reliable isolation for a wide range of liquid and gas media.

The valve is manually operated through a lever handle, making it simple to install, operate, inspect, and maintain. The flange-end connection allows secure installation in process piping systems, while the floating ball construction provides effective sealing with relatively low operating torque.

The API 602 SW End Forged Stainless Steel F304 Extended Stem Cryogenic Globe Valve with Drip Tray is a specialized shut-off and flow-control valve engineered for low-temperature and cryogenic fluid services. It combines a compact forged-body construction, stainless steel F304 material, socket-weld (SW) end connections, an extended stem/bonnet arrangement, and a drip tray designed to manage condensation and minimize the accumulation of frost around the operating area.

The API 623 Cast Steel Globe Valve is a reliable solution for demanding industrial applications requiring precise flow control, tight shut-off, and long-term durability. Its performance depends on advanced casting technology, strict heat treatment, accurate machining, professional painting protection, and correct material selection. With proper manufacturing control and inspection procedures, API 623 globe valves provide excellent reliability in steam systems, oil and gas facilities, petrochemical plants, and power generation projects. BOPIN Valve supplies OEM API 623 cast steel globe valves with customized designs, materials, pressure classes, coatings, and inspection standards to meet global industrial requirements.

ASME B16.34 Cast Steel Flanged Y Type Strainer for Steam System is a durable and efficient filtration solution for industrial steam applications. With a strong cast steel body, stainless steel filtering element, standardized flanged connections, and reliable pressure performance, it provides effective protection for valves, pumps, heat exchangers, and other critical equipment. By following international standards such as ASME B16.34, ASME B16.5, API 598, and ASTM material specifications, high-quality Y strainers deliver safe operation, easy maintenance, and long service life in demanding industries including power generation, petrochemical, oil & gas, and chemical processing.
