ANSI 150LB Titanium Floating Ball Valve, DN250, RF End

High-Performance Titanium Floating Ball Valve for Corrosive and Seawater Applications

The ANSI 150LB Titanium Floating Ball Valve, DN250 (10 Inch), RF Flanged End is engineered for demanding applications requiring outstanding corrosion resistance, lightweight construction, and reliable shut-off performance. Manufactured from premium Titanium Grade 2 or Grade 5, this floating ball valve is widely used in seawater desalination, offshore platforms, chemical processing, chlor-alkali plants, marine engineering, and other highly corrosive environments.

Designed in accordance with API 608, АСМЭ Б16.34, и ASME B16.5, the valve provides bubble-tight sealing, low operating torque, and excellent durability while maintaining full compliance with international industrial standards.

Why Choose a Titanium Floating Ball Valve?

Titanium is recognized as one of the most corrosion-resistant engineering metals available. Compared with stainless steel and duplex stainless steel, titanium offers exceptional resistance to seawater, chloride solutions, oxidizing acids, and many aggressive chemical media.

For critical process systems where corrosion failure cannot be tolerated, a titanium floating ball valve provides superior long-term performance and significantly reduces maintenance costs.

Key Advantages

• Outstanding resistance to seawater corrosion
• Excellent resistance to chloride-induced pitting and crevice corrosion
• Lightweight compared with steel alloys
• Bubble-tight shut-off
• Low operating torque
• Long service life
• Reduced maintenance costs
• Excellent reliability in aggressive chemical environments

Product Specifications

What Is a Floating Ball Valve?

A floating ball valve uses a free-floating ball supported by two resilient valve seats.

During operation:

1. The ball rotates 90° to open or close the valve.
2. Line pressure pushes the ball firmly against the downstream seat.
3. The resilient seat provides bubble-tight sealing with minimal leakage.
4. Quarter-turn operation allows fast and reliable isolation.

Floating ball valves are ideal for medium-pressure applications where dependable shut-off and simple operation are required.

Titanium Material Advantages

Titanium is widely selected for severe corrosion applications because of its naturally formed oxide film, which continuously protects the metal surface.

Excellent Corrosion Resistance

Titanium performs exceptionally well in:

• Natural seawater
• Chloride solutions
• Brine
• Sodium hypochlorite
• Wet chlorine
• Marine atmospheres
• Oxidizing acids

High Strength-to-Weight Ratio

Titanium offers:

• High mechanical strength
• Approximately 40% lower weight than many steel alloys
• Excellent fatigue resistance
• Long operating life

Outstanding Durability

Titanium valves typically provide significantly longer service life than carbon steel or stainless steel valves in corrosive service, reducing replacement frequency and lifecycle costs.

Key Design Features

Full Port Flow

The full-bore design minimizes pressure loss and allows unrestricted flow, making it suitable for process pipelines requiring maximum efficiency.

Bubble-Tight Sealing

Precision-machined titanium balls combined with PTFE or reinforced seats provide reliable shut-off and low operating torque.

Blowout-Proof Stem

The internally retained stem improves operational safety and prevents accidental stem ejection under pressure.

Anti-Static Device

Optional anti-static construction safely dissipates static electricity generated during operation, making the valve suitable for hydrocarbon service.

Fire-Safe Design

Optional fire-safe construction in accordance with API 607 provides additional protection for critical industrial installations.

Typical Applications

The Титановый плавающий шаровой клапан ANSI 150LB is widely used in:

Seawater Desalination Plants

Excellent resistance to seawater corrosion makes titanium the preferred choice for intake, discharge, and process pipelines.
