DGV CO., LTD. specializes in manufacturing and supplying high-quality butterfly valves, leveraging over 30 years of technological expertise and experience. DGV provides optimal valve solutions to meet the needs of diverse industrial sites.
DGV carefully selects superior corrosion-resistant and durable raw materials and conducts domestic casting and processing, obtaining both competitive pricing and high quality. In the domestic market, DGV has established itself as a recognized butterfly valve brand, offering unparalleled performance and value.

Eccentric Butterfly Valves
DGV’s eccentric butterfly valves are primarily used to control steam and other high-temperature, high-pressure fluids. Their simple design allows for a wide range of applications, from simple open & close operations to proportional control.
The eccentric butterfly valves feature a forceful fitting of the seat cover, fundamentally eliminating the source of leakage. Furthermore, key components of the valve ― such as the body, disc, and seat ― can be customized with materials suited to the operating environment, providing optimized solutions for customer needs.
The eccentric butterfly valves support both manual (lever, gear) and automatic (pneumatic, electric) driving methods, and are manufactured according to international standards such as KS, JIS, and ANSI. Available in various sizes up to 800 mm, the valves meet international safety and quality certifications such as ISO, KC, and CE.

Concentric Butterfly Valves
DGV’s concentric butterfly valves are primarily used for fluid control, such as water, and sewerage. Their simple structure ensures minimal failures and easy maintenance.
The concentric butterfly valves utilize a hard seat, ensuring superior durability even under high pressure. Non-copper butterfly valves with an inflatable seat, commonly used in secondary battery manufacturing processes, are also available.

FoM Engineering is the first company in Korea to specialize in producing butterfly valves applied to steam lines based on its extensive field experience. Currently it produces various kinds of advanced butterfly valves.

Triple Offset Butterfly Valve
4M-BTO model is manufactured based on fundamental triple offset valve structure. So that it is applicable in the condition of low or high temperature as well as high pressure. The combination of three offset provides an uninterrupted sealing surface, minimizes wear between the seat and seal, and preserves sealing integrity over the life cycle of the valve.
It is able to be designed as manual, automatic and proportional types of control according to customer’s needs, so very applicable for various conditions.
The triple offset valve has maximum working pressure of 100 bar (Customization available) and maximum working temperature: 650˚C (Customization available). To prevent the secession of the valve of the valve seat, it is fabricated as a structure fixed to the body and the structure is designed to maintain easily when pipes are laid.

Double Offset Butterfly Valve
4M-BDO model butterfly valve can be used in multi purposes. The application of the product can be customized depending on use environment.
The maximum working pressure is 50 bar and the maximum working temperature is 220˚C for RTFE seat and 600˚C for meatal seat. It is fabricated in dual large-diameter structure to improve the durability of the valve and to minimize the wear and tear of seat with a 4M unique seat structure, so the life of the valve is extended.

Concentric Butterfly Valve
The 4M-BCO model butterfly valve can be applied to cool water. The maximum working pressure is 20kgf/cm2 and the maximum working temperature is 0~90˚C for EPDM seat. To prevent the separation of the valve seat, it is fabricated into the tube seat structure, thereby reducing the torque with precision machining of the disc that then works smoothly.

Y-Pattern Angle Seated Valve
The 4M-Y pattern angle seated valve can be used for multiple purposes. The application can be customized depending on the environment. The maximum working pressure is 10kgf/cm2 and the maximum working temperature is 180˚C. Structurally it can be used as a check valve function and it is manufactured in light weight and compact so it can be installed in machinery and narrow spaces.
FoM Engineering has been recognized as a ‘technology innovation small and medium-sized enterprise (INNOBIZ)’ by the Ministry of SMEs and Startups (MSS). Moreover, FoM Engineering is striving to create better and more honest products by applying strict quality control through the quality management system (ISO9001).
