Lubricating oil: Lube-oil circulation

General service: Shipboard utility piping

Overview

Key Features:

Marine flange globe valve is a linear motion valve designed for both isolation and throttling service. Its name derives from the spherical body shape and the disk that moves perpendicular to the seat to control flow.

Key components and design features typically include:

1. Body Patterns: Available in straight-through (most common) and angle patterns. Straight-through valves have inlet and outlet connections aligned, while angle patterns have them at a 90-degree angle.

2. Bonnet Connection: Usually features a bolted yoke-type bonnet, allowing for easy maintenance and access to internal components.

3. Stem Operation: Most are outside screw and yoke (OS&Y) with a rising stem. This design visually indicates the valve's position (open/closed) and keeps the stem threads separate from the process fluid, reducing corrosion and wear.

4. Disc and Seat: Often have a renewable seat ring and a disc made of durable materials like stainless steel or bronze for a tight seal and long service life.

5. Flanged Ends: The ends are flanged for bolted connections to the pipeline, providing a strong, leak-proof joint suitable for the demanding marine environment.

6. Applications: Designed to handle a wide range of shipboard media, including sea water, fresh water, lubricating oil, fuel oil, and steam.

7. Actuation: While typically operated by a handwheel, they can also be fitted with electric, pneumatic, or other automated actuators
