Supports high temperatures up to 800℃, and also offers custom-made butterfly dampers with a welded structure. We will manufacture according to the customer's specifications.
We can broadly accommodate customer needs, from standard butterfly dampers with low prices and short delivery times to welded structure butterfly dampers. With the installation of high-performance proportional control operation devices, detailed control is possible. (Control)
Low price and short delivery time! High dimensional accuracy and low leakage have been achieved through internal machining of the main body.
The "WT type" is a butterfly damper suitable for blocking gases such as high-temperature gas and air. With the installation of a high-performance proportional control actuator, it allows for precise control and can be used over a wide temperature range from low to high temperatures. Additionally, the optimization of the shape through precision casting (lost wax) results in low cost and short delivery times. 【Features】 ■ Low cost and short delivery time due to shape optimization through precision casting ■ Suitable for blocking gases such as high-temperature gas and air ■ High dimensional accuracy and low leakage achieved through machining of the inner surface of the main body ■ Precise control enabled by the installation of a high-performance proportional control actuator ■ Usable over a wide temperature range from low to high temperatures *For more details, please refer to the PDF document or feel free to contact us.
Ideal for gas insulation! Usable over a wide temperature range from low to high temperatures.
The "WL type" is a butterfly damper that employs a lug-type flange and external bearings. It is suitable for blocking high-temperature gases, air, and other gases, and achieves high dimensional accuracy and low leakage through machining of the inner surface of the main body. Additionally, it allows for precise control by incorporating a high-performance proportional control actuator. We offer various options. For details on the types, prices, and delivery times of each option, please contact us. 【Features】 ■ Adopts lug-type flange and external bearings ■ Well-suited for blocking high-temperature gases, air, and other gases ■ Achieves high dimensional accuracy and low leakage through machining of the inner surface of the main body ■ Allows for precise control with the incorporation of a high-performance proportional control actuator ■ Usable over a wide temperature range from low to high temperatures *For more details, please refer to the PDF materials or feel free to contact us.
The drive modes include "L (manual lever)", "U (manual gear)", and "A (air)", among others!
We would like to introduce the types of "Butterfly Dampers" that we handle. The types consist of "N (non-sealed concentric axis)," "S (semi-sealed concentric axis)," and "H (sealed eccentric axis)," with shaft seals being "G (gland)" and "V (oil seal)." The shaft materials available are "P (S45C lining)" and "R (420J lining)." 【Explanation of the model (for KND-0800GPL)】 ■K: Manufacturer name (Koken Co., Ltd.) ■N: Type ■D: Damper ■0800: Dimension (mm) ■G: Shaft seal ■P: Shaft material ■L: Drive method *For more details, please refer to the PDF document or feel free to contact us.
Suitable shapes, dimensions, and materials can be selected according to the application! Lightweight, low-cost steel plate dampers.
The "Butterfly Damper SD type" is a product made of welded steel plate construction. It is used for ON-OFF control of various gases and air. Additionally, due to the lack of constraints such as wooden molds during the manufacturing process, large-diameter louver dampers can also be produced. 【Features】 ■ Suitable shapes, dimensions, and materials can be selected according to the application ■ Lightweight and low cost ■ No constraints such as wooden molds during the manufacturing process ■ Large-diameter louver dampers can also be produced *For more details, please refer to the PDF materials or feel free to contact us.
Completely sealed gas and air from room temperature to ultra-high temperature! Lightweight, low-cost, high airtightness shut-off valve.
We would like to introduce our "Butterfly Damper D-type." This product is made of steel plates and is a highly airtight damper specifically designed for high-temperature gases (MAX 600℃) as a shut-off valve. It is widely used in steel plants, boiler facilities, fumigation equipment, common flues, solvent recovery, and more. Please feel free to contact us when you need assistance. 【Features】 ■ Completely seals gases and air from room temperature to ultra-high temperatures ■ Lightweight and low-cost ■ High airtightness ■ Widely used in common flues, solvent recovery, and more *For more details, please refer to the PDF materials or feel free to contact us.
All types can be manufactured: air-operated, electric, hydraulic, and manual! Available in round and square shapes, accommodating diameters of up to approximately 3500mm.
The "Butterfly Damper" is commonly used for shut-off, flow control, and balancing in general applications. It can be installed in narrow spaces when mounted in ducts. It consists of a casing, blades, shaft, gland device, sealing device, and drive unit. Additionally, by rotating the blades normally between 0° and 90°, flow control and shut-off can be achieved. 【Features】 ■ Can minimize pressure loss when the damper is fully open ■ Provides a wide range for flow control ■ Ensures high sealing by using an elastic sheet ■ Can adapt to temperature changes from low to high temperatures and temperature differences within the duct, ensuring high sealing ■ Suitable for continuous operation *For more details, please download the PDF or feel free to contact us.
