Marine Double Flange Butterfly Valve PN16

Marine Double Flange Butterfly Valve is engineered for heavy-duty marine and industrial pipelines where durability and efficient flow regulation are essential. The double flange design provides rigid mounting and enhanced sealing performance, making it suitable for critical ship systems exposed to vibration and pressure changes.

Manufactured using marine-grade materials, this valve delivers smooth quarter-turn operation and low torque performance. Its compact structure allows easy installation in confined engine room spaces while maintaining high reliability for seawater, cooling, and general service lines.

Designed to meet PN16 pressure requirements, the valve is widely used across marine ballast systems, fire fighting pipelines, HVAC circuits, and seawater intake applications.
