Metal Seated Butterfly and Knife Gate Valves for Oil & Gas, Steam and Thermal Industries
Designed and manufactured in South Korea, our metal seated butterfly valves and multi seated knife gate valves surpass the toughest requirements in steam, oil gas, and thermal industries. Control options for both butterfly valves and knife gate valves include manual, hydraulic, electric, and pneumatic.
Built on breakthrough innovations and continuous investment in R&D, the metal seat and knife gate valves are produced using the most precise technology and equipment and meet multiple international standards, including ISO9001, CE – PED ABS, BV, DNV,GL, LR, and RINA. Some of our global clients include Samsung Heavy Industries, FNW, Hanjin Heavy Industries & Construction, STX Offshore & Shipbuilding, DSEC, Arcadia, Chandris, and EAS.
Metal Seated Butterfly Valves | All Metal Seat | Fire Safety
The world’s first all metal seat to attain a Class VI seal rating, the ultra-precise, stainless steel disc is a durable perfect seal providing outstanding corrosion resistance.
Engineered for the most demanding environments, including high temperature and high pressure flow control, our all metal butterfly valves are used for oil & gas, thermal, steam, and shipbuilding applications. Revolutionary all metal butterfly valves create a bubble tight seal; the seat and body are produced from the highest-grade metal alloys
Knife Gate Valves | Multi Seat Combinations
Engineered to higher standards to provide the best performance possible, our multi seat knife gate valves offer all metal knife gate and resilient NBR seat (rubber) knife gate models.
Depending on the flow control requirements of the job, the knife gate valves we offer feature the stainless steel seat and the easily replaced flexible NBR seat options. Creating a bi-directional seal and featuring an innovative inverted packing box design, our knife gate valves are suitable for use in oil & gas, chemical plants, power generation, wastewater treatment plants applications.
A variety of manual and powered operators and options are available to suit your actuation needs.
Cryogenic Valve | Metal Seat Butterfly Valve
Manufactured for cryogenic applications and services, the cryogenic butterfly valves are installed for protection against overpressure in tankers and containers used for the storage, distribution and transportation of liquefied gases. Cryogenic butterfly valves operate under -320°F (-196 °C).
