Marine-Certified Butterfly Valves for Shipbuilding

Type-approved butterfly valves for shipbuilding, marine vessels, and offshore platforms. Our DNV GL classified and Lloyd's PED certified valve range meets the stringent requirements of maritime piping systems — from ballast water and seawater cooling to fuel oil and engine room applications.

Industry Challenges

Key valve selection considerations for shipbuilding & marine applications.

Classification Society Approval

Marine valves must be type-approved by classification societies such as DNV GL and Lloyd's Register to be installed on classified vessels. TTV valves hold DNV GL type approval under DNVGL-CP-0186.

Seawater & Corrosion Resistance

Ship piping systems handle seawater ballast, cooling water, and bilge water — all highly corrosive. Valve materials must resist long-term marine corrosion without degradation.

Pressure Equipment Compliance

Marine piping systems fall under the Pressure Equipment Directive (PED 2014/68/EU). All valves must be CE marked and certified by a notified body such as Lloyd's Register.

Compact & Lightweight Design

Space and weight are critical on vessels. Butterfly valves offer a compact, lightweight alternative to gate and globe valves, reducing installation footprint in engine rooms and machinery spaces.

Applications

Ballast water systems
Seawater cooling
Fuel oil systems
Engine room piping
Bilge and drainage
Fire main systems
HVAC on vessels
Offshore platform piping
