Product Overview
This angle bellows stop valve (also known as angle bellows seal stop valve) is a high-performance right-angle industrial control valve, designed and manufactured in full compliance with major international industrial valve standards including ISO, EN, DIN, ASME and GOST, exclusively developed for 90° pipeline corner working conditions.
It adopts an integrated 90° right-angle valve body structure, built-in 316 stainless steel bellows + packing dual seal system, with dual core functions of pipeline on-off shut-off and precise flow & pressure regulation, completely eliminating the risk of medium leakage from the valve stem. It can directly replace the combination of “straight-through valve + 90° elbow” at pipeline corners, reducing pipeline joints and leakage points, greatly saving installation space and construction costs.
With international standard flanged connection, full size range from DN15 to DN400, and customizable multi-material valve body, this valve is widely used in petrochemical, power plant, HVAC heating, pharmaceutical and water treatment industries. It is the preferred special valve for 90° pipeline corner installation worldwide, and a core model for foreign trade project supporting and bulk procurement.
Core Product Features
- Integrated 90° Right-Angle Structure, Space & Cost SavingThe valve body has an integrated 90° right-angle design for inlet and outlet, which can be directly installed at the pipeline corner without additional 90° elbows. It reduces pipeline welding/flange joints, greatly lowers pipeline leakage risk, shortens fluid flow path, saves installation space, and cuts down on-site material and labor costs, perfectly solving the adaptation pain point of straight-through valves in corner pipeline installation.
- Low-Resistance Streamlined Flow Channel, Stable OperationThe right-angle flow channel is optimized with large curvature streamlined design, ensuring smooth fluid steering without dead angle, turbulence or medium retention. Compared with the conventional “straight valve + elbow” combination, it has significantly lower fluid resistance and pressure loss. It opens and closes smoothly without impact, effectively suppresses water hammer, runs without noise and vibration, and is suitable for long-term continuous operation.
- Dual Bellows Seal System, Zero Leakage ProtectionAdopts thickened 316 stainless steel integrally welded bellows + high wear-resistant packing dual seal structure, which completely isolates the valve stem moving parts from the pipeline medium, thoroughly solving the common problem of medium leakage caused by valve stem lifting wear of traditional stop valves. Its sealing performance meets ANSI B16.104 Class VI and EN 12266 zero leakage standards, with double protection for higher safety, fully complying with global environmental and safety regulations.
- Customizable Multi-Material Options, Wide Working Condition AdaptabilityThe valve body and wetted parts can be customized with international standard materials: ductile iron, WCB carbon steel, 304/316 stainless steel. It has excellent wear resistance, corrosion resistance and oxidation resistance, and is stably compatible with water, steam, thermal oil, oil products, weak corrosive media, clean fluids and other media, covering full scene requirements from conventional to mildly corrosive working conditions.
- Global Standard Compatibility, Full Size & Pressure CoverageAdopts international standard flanged connection, fully compatible with major global flange standards including EN, DIN, ASME, GOST, with unified dimensional specifications, can be directly connected to the existing pipeline systems of customers around the world without modification. Full size range from DN15 to DN400, nominal pressure covering PN16-PN100 (Class 150-Class 600), perfectly adapting to the pipeline supporting needs of different countries and working conditions.
- Easy Operation & Low Full-Cycle Maintenance CostEquipped with non-slip labor-saving handwheel for smooth manual operation, no additional power device required. Compact structure with no quick-wear parts, no complicated daily maintenance needed, and the bellows assembly has a long fatigue resistance life, greatly reducing the full life cycle operation and maintenance cost of the valve. Each valve undergoes strict hydraulic and pneumatic seal tests before delivery, with stable and reliable performance in line with international general quality inspection standards.
