Cast Steel Double Flange 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.

Suitable for ship ballast equipment, ballast piping systems, bilge water systems, and outboard positions.

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. Pneumatic actuator

The actuator can also be equipped with limit switches.

The valve body material is carbon steel, which has stronger corrosion resistance and pressure bearing capacity.
