Double Seated Control Valve
The Double Seated Control Valve is designed for precise modulation of flow, pressure, and temperature in demanding process applications. Its balanced double-seat construction provides high flow capacity with reduced actuator thrust, ensuring stable operation, excellent control accuracy, and extended service life. Suitable for handling steam, liquids, gases, and various process media, it is widely used in power plants, refineries, chemical, petrochemical, and general industrial applications.
