Double eccentric high-performance Butterfly Valves are an advanced type of valve commonly used in industries where high performance, reliability, and tight shut-off are required. These valves are characterized by their unique design, which includes a double offset mechanism, setting them apart from standard butterfly valves. Understanding their appearance and identifying features is crucial for engineers, operators, and maintenance personnel to ensure correct application and operation.

Bellows Globe Valves are essential components in a wide range of industrial applications where the prevention of leakage, precise flow control, and the ability to withstand demanding operating conditions are critical. The bellows in these valves act as a sealing mechanism to prevent fluid leakage around the valve stem, which is crucial in industries dealing with hazardous, toxic, or corrosive fluids. While the bellows are an integral part of the valve's performance, the overall quality of a bellows globe valve is influenced by a range of factors, from material selection to manufacturing precision and performance under different operating conditions. BOPIN VALVE will explore the key factors that determine the quality of bellows globe valves, focusing on aspects such as material selection, design integrity, manufacturing precision, performance characteristics, and reliability.

Dimpling is a process of machining countersunk holes on flanges to ensure a good fit between bolt heads or nuts and the flange surface, avoiding stress concentration. For low-pressure and small-diameter valves, the requirements for countersunking processing need to be analyzed in conjunction with specific standards and application scenarios.

Dec. 12, 2025 – Istanbul, Turkey – A leading global valve manufacturer has announced the successful shipment of a large order of Butt-Welded End Triple Offset Butterfly Valves to Turkey, marking a significant expansion into the country’s rapidly growing industrial sector. The order is expected to bolster the country’s energy, chemical, and water treatment industries with advanced valve technology known for its superior sealing performance and durability.

In a significant development for the industrial valve sector, a new order of DIN 3356 Flange End GS-C25 Bellows Sealed Globe Valves has been confirmed by BOPIN VALVE for delivery to the Russian market. This shipment reflects the continued demand for high-performance sealing technologies in critical industries such as oil and gas, power generation, and chemical processing across Russia. The order represents not only a commercial milestone for the manufacturer but also a reaffirmation of the growing reliance on advanced European valve standards in Russian industrial infrastructure.

Choosing the best bellows for a bellows-sealed valve is critical to ensure reliable performance, leak prevention, and long service life, especially in demanding applications where valves are exposed to high pressures, temperatures, and potentially corrosive or abrasive environments. The bellows seal is designed to prevent leakage of fluids, gases, or other media by providing a tight seal between the valve stem and the valve body, while also allowing the valve to open and close without causing wear on the sealing surfaces.

A shot blasting facility is an industrial setting where a process called shot blasting is performed. Shot blasting is a method of cleaning, strengthening, or polishing metal, concrete, or other surfaces through the use of abrasive media (usually steel shot or grit) propelled at high speed using mechanical means. This process is commonly used for surface preparation, such as cleaning rust or corrosion from metal surfaces, creating a rough texture for better coating adhesion, or improving the mechanical properties of materials.
