Class Approved Valves – Certified Valves for Marine & Offshore Systems

Class approved valves are marine valves certified to meet vessel classification society requirements and marine safety standards.
These valves are designed and tested for reliable performance in critical shipboard and offshore applications.
Class approval confirms compliance with pressure rating, material quality, and operational safety requirements.
Using class approved valves supports inspection readiness, reduced risk, and safe vessel operation.

Why Class Approval is Important

Ensures valves meet strict requirements for marine safety and operational reliability.
Required for critical shipboard pipelines where valve failure can lead to leaks or shutdown.
Supports vessel inspections, surveys, and classification audits.
Reduces risk of non-compliance and costly delays during port calls or shipyard repairs.

Marine Applications for Class Approved Valves

Main engine and auxiliary engine systems.
Fuel oil and lubrication oil circuits.
Seawater and freshwater cooling networks.
Ballast and bilge pipelines.
Firefighting and emergency safety systems.
Hydraulic and pneumatic onboard systems.
Offshore utility and process piping systems.

Types of Class Approved Valves Supplied

Gate Valves for full isolation and unrestricted flow.
Globe Valves for throttling and flow regulation.
Check Valves to prevent reverse flow and protect pumps.
Ball Valves for quick shut-off with tight sealing.
Butterfly Valves (wafer, lug, high performance, triple offset) for large pipelines.
