- Key Products/Technologies
- Butterfly Valves: Rubber-seated eccentric type valves feature easy quarter-turn operation with low torque, and a streamlined disc structure for minimal fluid resistance. Valves with a nominal diameter of 800A or larger allow for rubber seat replacement without removal from the pipeline. Metal-seated eccentric type valves are a flagship product recognized as a superior product by the Public Procurement Service, extending seat life and minimizing maintenance through a metal-to-metal seat combination, and reducing operating force due to a lower friction coefficient. Polyurethane butterfly valves incorporate elastic polyurethane seats on the body and disc, suitable for positive and high-pressure (20kgf/㎠) applications, and are eco-friendly for use in various environments like seawater, purified water, sewage, and wastewater without additional painting. The product line includes manual, electric, hydraulic, and pneumatic operating types.Butterfly Valves: Rubber-seated eccentric type valves feature easy quarter-turn operation with low torque, and a streamlined disc structure for minimal fluid resistance.

- Ball Valves: Rubber-seated ball valves, recognized as superior products by the Public Procurement Service, feature quarter-turn operation and can be operated manually, electrically, hydraulically, or pneumatically. Hydraulic type ball valves for water use are EM (Excellent Technology) certified products, featuring a piston sealing system for perfect shut-off. They include an emergency close function via a solenoid valve during power outages and an externally adjustable structure for internal seat leakage. Full port type ball seats ensure quiet fluid transfer, and hydraulic/pneumatic ball valves are optimized for pump stations to protect pumps from water hammer and backflow.Ball Valves: Rubber-seated ball valves, recognized as superior products by the Public Procurement Service, feature quarter-turn operation and can be operated manually, electrically, hydraulically, or pneumatically.
