Metallurgically Bonded for Permanent Leakproof Performance: The BW Check Valve(Butt Weld) connection fuses the valve and pipeline into a single integral unit via welding, fundamentally eliminating the interfacial leakage risks caused by gasket aging or bolt loosening in flange connections. This is an intrinsic safety requirement for conveying toxic, hazardous, flammable, explosive or high-value media.
Smooth & Dead Leg-Free Design: The seamless, cavity-free transition zone of the weld prevents medium residue, bacterial growth or crystal blockage, meeting the stringent hygiene and cleanliness standards of the food, pharmaceutical, high-purity chemical and other industries.
Withstands Extreme Operating Conditions: The fully welded structure can endure higher pressure, temperature and severe thermal cycling, free from the issues of bolt creep or gasket failure associated with flange connections. It is suitable for applications involving high-temperature steam, cryogenic liquids and frequent pressure fluctuations.
Vibration and Fatigue Resistance: Welded joints offer superior resistance to mechanical vibration and pressure pulsation fatigue compared with flange connections, making them the ideal choice for high-vibration environments such as compressor outlets, reciprocating pump bypasses and offshore platforms.
Integrated Corrosion Resistance: The valve and pipeline can be welded using the same material and undergo uniform internal anti-corrosion treatment (e.g., lining, coating), forming a continuous and even anti-corrosion layer that extends the service life of the entire system.
True Full Bore Design Realized: Precision bevel machining and welding ensure perfect matching and smooth transition between the valve inner diameter and pipeline inner diameter, maximizing flow passage unobstructedness and leveraging the ultra-low flow resistance advantage of the double-disc check valve.
Consistent Performance Throughout Service Life: The robust welded structure maintains long-term alignment of the internal double-disc hinge mechanism, preventing valve disc eccentric wear and sealing failure caused by loose connection points, thus ensuring stable valve performance over its entire lifecycle.
Maintenance-Free for Life: After welding, there is no need for periodic bolt retightening or gasket replacement as required for flange connections, achieving zero lifecycle maintenance costs.
Space and Weight Savings: The complete elimination of flanges, bolts, nuts and gaskets significantly reduces system weight and minimizes installation envelope space, delivering exceptional value for modular designs, offshore facilities and retrofitting projects with space constraints.
