Concentric Double Flanged Butterfly Valve

Specially designed for ship and maritime applications, in compliance with GB/T3036, the valve structure is compact and suitable for installation environments with small ship space.

Mid line valve body design, high flow rate, low fluid flow resistance, and low pressure loss

Vulcanized valve seat design isolates the valve body and medium, achieving better sealing, corrosion resistance, and tensile performance.

The widened design of the valve seat sealing surface reduces the risk of installation leakage.

Double sealing design effectively reduces the risk of valve shaft loosening and leakage.

Multiple standard options are available for side flanges.

The valve body is coated with epoxy paint with a thickness of 175 microns or more, providing stronger corrosion resistance.

This series can be equipped with multiple drives such as worm gearboxes, electric and pneumatic actuators according to different on-site working conditions and control requirements.

The whole machine has passed the sulfur dioxide and salt spray tests, with stable product performance and long service life.

Suitable for ship ballast water treatment equipment, ballast pipeline systems, bilge water systems, fuel oil systems, desulfurization and denitrification systems, etc.
