Key Characteristics & Typical Applications

• Flow Control: Excellent for throttling and flow regulation.

• Pressure Drop: High compared to gate valves due to the S-shaped flow path.

• Shut-off Capability: Provides tight sealing.

• Durability & Maintenance: The SDNR design makes it robust and easy to maintain. The renewable seat is a key feature for longevity.

• Space Consideration: The non-rising stem is ideal where vertical space is limited.

Typical Applications:

• Marine & Shipbuilding: Mainly for shipboard systems like bilge lines, ballast systems, cooling water systems, fuel oil lines, and steam service (auxiliary lines). This is the primary application implied by the JIS F standard.

• Offshore Platforms: Various process and utility services.

• General Industry: Used in power plants, chemical plants, and oil refineries for steam, water, and other non-aggressive fluids where regulation is required.
