CL1500 Trunnion Ball Valve: Powering Critical Industrial Operations

In high-pressure piping systems where reliability is non-negotiable, the CL1500 Trunnion Ball Valve stands as an engineering marvel. Designed for extreme conditions in oil, gas, and petrochemical industries, this valve combines robust construction with precision performance. Let’s explore why it’s a top choice for engineers worldwide.

What Is a CL1500 Trunnion Ball Valve?

A CL1500 (Class 1500) Trunnion Ball Valve is a high-pressure valve featuring:

Trunnion-mounted design: A fixed ball supported by mechanical anchors (trunnions) for reduced operating torque
Full-bore or reduced-bore options: Optimized for flow efficiency or space constraints
Fire-safe certification: Compliant with API 607/6FA standards
Double-block-and-bleed (DBB) capability: Enhanced safety for isolation and maintenance

Key Features & Benefits

1. Unmatched Pressure Handling

Rated for 1500 Class (PN 260), these valves withstand pressures up to 3,800 psi (262 bar), making them ideal for:

Offshore drilling platforms
High-pressure gas transmission
Refinery critical service

2. Superior Sealing Technology

Spring-loaded seats: Maintain tight seals even during pressure fluctuations
Anti-blowout stem: Prevents stem ejection under extreme conditions
PTFE or metal-seated options: Choose between zero-leakage soft seals or high-temp metal seals

3. Durability in Harsh Environments

ASTM A216 Gr. WCB/LCB bodies: Corrosion-resistant construction
Stellite-hardened ball & seats: Wear resistance in abrasive media
Extended temperature range: -46°C to 200°C (-50°F to 392°F)

4. Operational Efficiency

Low torque operation: 30-50% less effort than floating ball valves
Gearbox or actuator compatibility: Easy automation integration

Applications of CL1500 Trunnion Ball Valves

These valves excel in critical services:

Subsea pipelines – Resists seawater corrosion and high external pressures
Gas compression stations – Handles rapid pressure surges
Chemical injection systems – Compatible with aggressive media
Cryogenic LNG terminals – Maintains performance at ultra-low temperatures
