Source the factory‑direct PN16 DN250 Gearbox Globe Valve with Bolted Bonnet from OEM manufacturer Hanno Valve for municipal heating, regional water networks, and industrial utility lines. Specifically proportioned for DN250 (10‑inch) piping systems running under PN16 nominal working pressure, this Hanno valve balances operational ease with structural maintainability. The bolted bonnet design provides open top‑entry access to internal seating surfaces, reducing facility downtime during maintenance cycles, while the precoated sand cast 25L steel body provides structural rigidity against pipeline stress.

Order directly from Hanno Valve, the Large Diameter Gearbox Driven Cast Steel Globe Valve for main steam and oil pipelines. Designed to overcome extreme hydrodynamic drag in large bores, its enclosed industrial gearbox provides smooth, high-torque disc control. Cast in our own foundry using advanced precoated sand techniques, the high-density steel shell eliminates shrinkage porosity and ensures absolute dimensional stability under pressure.

Source from Hanno, a certified manufacturer, the Bevel Gear Operated Flanged Globe Valve for High Pressure. Engineered for thermal power and chemical lines, it integrates a heavy-duty bevel gear reducer to drastically cut operating torque under high differential pressure. Cast via an in-house precoated sand process at our 18,000㎡ Zhejiang facility, it guarantees zero deformation and leak-free steam control.

Hanno Valve produces High temperature gate valve with heat dissipation, thermal oil, flue gas and other industrial service conditions. Designed with extended bonnet and heat-dissipation features, the valve helps limit heat transfer to the packing and stem sealing area during operation.
