Manual Butterfly Valve

The main components of the Manual Butterfly Valve from FUXEON® include the valve body, valve stem, valve disc, sealing ring and transmission device. The main materials of the valve body are cast iron, ductile iron, carbon steel and stainless steel. The main material for the valve stem is stainless steel and spheroidal cast iron. The material for the valve plate is spheroidal cast iron and stainless steel. The material for the sealing ring is EPDM, NBR, and PTFE. Butterfly valves are commonly used in fire protection systems, municipal water supply and drainage systems, industrial pipeline systems, and municipal water supply and drainage systems.

FAQ

Q1: Which pipeline systems are manual butterfly valves suitable for?

A: Manual butterfly valves are widely applied in water supply and drainage systems, fire protection systems, HVAC, industrial pipelines, municipal engineering, and sewage treatment. They are ideal for on-off control of media in large-diameter pipelines, especially suitable for scenarios where manual operation is convenient and frequent switching is not required, such as building fire hydrant pipelines, cooling water pipelines, and sewage discharge pipelines.

Q2: What types of media can manual butterfly valves handle?

A: They are suitable for clean media such as water, air, and oil, as well as mild corrosive liquids and sewage. Soft-seal manual butterfly valves (EPDM/NBR seals) are suitable for non-corrosive media, while hard-seal models can handle slightly corrosive media, but are not recommended for high-concentration corrosive fluids or media with large solid particles.

Q3: What are the core application advantages of manual butterfly valves?

A: They have a compact structure, lightweight design, and small installation space, especially suitable for large-diameter pipelines. Manual operation is simple and labor-saving, with a 90° quarter-turn switch to realize quick on-off control. The sealing performance is reliable, and the cost is lower than other manual valves, making them cost-effective for large-scale application.
