For accurate butterfly valve selection, please send your pipe size, pressure rating, working temperature, medium, end connection, body material, seat material, operation method, flange standard and required certificates.
Butterfly valve selection should start from the actual working conditions, not only pipe size. Media, pressure rating, temperature, body style, disc material, seat material, end connection, operation method and required standards all affect the final butterfly valve configuration.
Start with the media and service condition. Clean water, wastewater, air, gas, cooling water, chemical liquid, oil and corrosive fluids may require different butterfly valve body materials, disc coatings and seat designs. EPDM, NBR or soft seated butterfly valves are often reviewed for water and HVAC service, while PTFE lined or corrosion-resistant options may be selected for chemical media.

Confirm pipe size, DN or NPS, pressure class, working temperature, flow requirement and pressure drop before selecting a butterfly valve. Low-pressure water systems may use resilient seated wafer or lug designs, while higher pressure, higher temperature or larger pipeline projects may require high performance, metal seated or offset butterfly valve structures depending on the order specification.

Match the butterfly valve type to the installation and maintenance plan. Wafer butterfly valves are compact for standard flange installation, lug butterfly valves support easier pipeline maintenance, flanged butterfly valves are commonly reviewed for larger pipelines, and high performance or triple offset butterfly valves are considered when tighter sealing, higher pressure or demanding service is required.

Body, disc, shaft and seat materials should match corrosion risk, temperature, pressure, media compatibility and leakage requirements. Cast iron, ductile iron, carbon steel, stainless steel, EPDM, NBR, PTFE, FKM, soft seated and metal seated options can be reviewed according to the medium and project specification.

Confirm the end connection, flange standard and operation method before quotation. Butterfly valves can be supplied as wafer, lug, flanged or double flanged designs, with lever, worm gear, pneumatic actuator, electric actuator or hydraulic actuator operation. For project orders, also confirm required standards, certificates, drawings, inspection records and test documents.

An industrial butterfly valve uses a quarter-turn disc mounted on a stem to open, close or regulate flow in a pipeline. When the disc rotates parallel to the flow path, media can pass through the compact valve body. When the disc turns 90 degrees, it presses against the seat to shut off the flow. Butterfly valves are widely used for water, HVAC, chemical, power, oil and gas, utility and general industrial pipeline service.
Quarter-Turn Disc Movement: The stem rotates the disc 90 degrees by lever, worm gear, pneumatic actuator, electric actuator or hydraulic actuator.
Open Flow Position: When the disc is parallel to the pipeline, the valve allows flow through a compact body with relatively low pressure loss.
Closed Sealing Position: When the disc turns closed, the disc and seat contact the sealing surface to block the flow path.
Body Style Matching: Wafer, lug, flanged, high performance and triple offset butterfly valves are selected according to pressure, media and maintenance needs.
Manual or Automated Service: Butterfly valves can support local shutoff, remote operation, flow control and automated process systems.
Butterfly valves open and close with a 90-degree disc rotation, making them suitable for quick isolation and frequent operation.
The slim disc and compact body help reduce installation space while supporting shutoff, isolation and basic throttling service.
Common body styles include wafer butterfly valves, lug butterfly valves, flanged butterfly valves and double flanged designs.
Lever, worm gear, pneumatic, electric and hydraulic operation options can support local control or automated plant systems.
EPDM, NBR, PTFE, FKM, soft seated and metal seated options can be reviewed according to media, temperature and leakage requirements.
Cast iron, ductile iron, carbon steel, stainless steel, rubber lined and PTFE lined options can be matched to water, air, gas, oil and chemical media.
High performance and triple offset butterfly valves can be reviewed for higher pressure, higher temperature or demanding shutoff applications.
Drawings, datasheets, certificates, inspection records and technical files can support butterfly valve approval and purchasing work.

A butterfly valve is used for shutoff, isolation and flow control in pipelines. It uses a quarter-turn disc to open, close or regulate media such as water, air, gas, oil, wastewater and compatible chemical fluids.
A wafer butterfly valve is installed between two pipe flanges and is usually selected for compact, economical installation. A lug butterfly valve has threaded lug holes, which can support easier maintenance and partial pipeline disassembly in suitable systems.
A flanged butterfly valve is often reviewed for larger pipelines, easier alignment, higher installation stability or projects where the valve body needs its own flanged connection. Final selection depends on size, pressure, flange standard and site layout.
Soft seated butterfly valves use materials such as EPDM, NBR, PTFE or FKM and are commonly reviewed for water, HVAC and general service. Metal seated butterfly valves are considered for higher temperature, abrasive media or more demanding shutoff service.
A triple offset butterfly valve is usually reviewed for high performance shutoff, higher pressure or temperature, metal seated service and demanding industrial pipelines. Suitability depends on the medium, pressure class, temperature and leakage requirement.
Yes. Butterfly valves can be supplied with pneumatic, electric or hydraulic actuators for remote operation, automated on-off control, process control systems and plant automation requirements.
Please provide valve type, pipe size, pressure rating, working temperature, media, body material, disc material, seat material, end connection, operation method, quantity and any required standards, test reports or certificates.
