304 Or 316 Grade Stainless Steel Butterfly Valve

Due to 304 Or 316 Grade Stainless Steel Butterfly Valve’ structural limitations, it is not suitable for industries that are resistant to high temperatures, high pressures, corrosion, and wear. A relatively advanced butterfly valve is the three eccentric metal hard seal butterfly valve, where the valve body and valve seat are connected components, and the sealing surface layer of the valve seat is welded with heat-resistant and corrosion-resistant alloy materials. The multi-layer soft stacked sealing ring is fixed on the valve plate. Compared with traditional butterfly valves, this butterfly valve has the advantages of high temperature resistance, easy operation, frictionless opening and closing, and compensating for the sealing with the increase of torque of the transmission mechanism when closing, which improves the sealing performance and prolongs the service life of the butterfly valve

Stainless steel butterfly valvesare one of the best-selling products of Zhongguan valves, often exported to Southeast Asian countries, and there are also distributors in five Central Asian countries
Valve body: It is usually made of stainless steel (such as 304, 316, etc.), which has strong corrosion resistance and is suitable for various working conditions.
plate: a disc-shaped structure that controls the flow of fluid through rotation. The butterfly plate material may be consistent with the valve body or other wear-resistant/corrosion-resistant materials may be used.
Valve stem: connects the actuator to the butterfly plate, transmitting torque to achieve switching or adjustment.
Sealing ring: Common materials include rubber, PTFE, or metal seals to ensure the sealing performance when the valve is closed.
Execution mechanism: manual (handle, worm gear), electric, pneumatic or hydraulic drive mode

Application

Stainless steel butterfly valves can be used in many different fields, such as water treatment: municipal water supply, sewage treatment.

Chemical/Pharmaceutical: Transport of corrosive media (requiring high-grade stainless steel such as 316L).

Food and Beverage: Sanitary grade butterfly valves (polished to meet FDA standards).

HVAC: Cold and hot water circulation system.

Ship/Energy: Seawater systems, boiler pipelines.              

Notes

attention should also be paid to the following issues regarding the characteristics of the stainless steel butterfly valve: corrosiveness, temperature, and particle content (when selecting sealing materials).

Pressure rating: PN10, PN16, etc. (selected according to the pipeline design pressure). Connection methods: flange type, clamp type, welding type (depending on the pipeline interface).

Standard certification: API, ANSI, ISO or national standard (such as GB/T 12238).
