DTC-BUTTERFLY VALVE Series
DTC supplies high-quality industrial butterfly valves for reliable flow isolation and regulation. Available in wafer, lug, and flanged designs with carbon steel, stainless steel, and ductile iron options. Manufactured according to API 609, EN 593, and ASME standards for water, HVAC, fire protection, and industrial piping systems.
A butterfly valve is a quarter-turn rotary valve that uses a circular disc mounted on a rotating shaft to control fluid flow. When the valve is opened, the disc rotates parallel to the flow direction, allowing fluid to pass through. When closed, the disc rotates 90 degrees and blocks the pipeline.
Due to its compact structure, lightweight design, low installation cost, and fast operation, butterfly valves are widely used in large-diameter piping systems where space and efficiency are important considerations.
DTC supplies industrial butterfly valves including wafer butterfly valves, lug butterfly valves, and flanged butterfly valves in various materials such as ductile iron, carbon steel, stainless steel, and alloy steel.
Our butterfly valves are suitable for applications requiring reliable shut-off, flow regulation, and automated control.
Compared with gate and globe valves, butterfly valves require less installation space and are lighter in weight, reducing transportation and installation costs.
The valve can be fully opened or closed with a 90-degree rotation, allowing quick operation.
Butterfly valves are an economical choice for medium and large pipeline systems.
Available operation methods:
The disc position can be adjusted to regulate flow in many industrial applications.

A wafer butterfly valve is installed between two pipe flanges and secured using flange bolts.
A lug butterfly valve has threaded inserts around the valve body, allowing installation with individual bolts.
A flanged butterfly valve connects directly to pipeline flanges.
A triple offset butterfly valve uses an advanced disc and seat design to eliminate rubbing between sealing surfaces.

Available documents:
A butterfly valve is a quarter-turn valve using a rotating disc to control fluid flow in a pipeline.
A wafer butterfly valve is installed between two flanges, while a lug butterfly valve has threaded holes that allow independent bolt installation and removal.
Standard butterfly valves are mainly used for low and medium pressure applications. Triple offset butterfly valves are suitable for higher pressure and temperature services.
Butterfly valves are widely used in water treatment, HVAC, fire protection, oil & gas, chemical processing, and industrial systems.
