Product Description

Key Features

Efficient Maintenance

The top-entry structure and retractable seat design allow for quick, online replacement of the valve core and seals, eliminating the need for pipeline removal and reducing downtime by up to 80%.

Comprehensive Safety Protection

Includes stem blowout prevention, electrostatic grounding, and fire-safe backup seals, providing reliable protection in extreme and hazardous operating environments.

Enhanced Stability & Durability

The one-piece cast valve body reduces leak points, while the fixed ball and trunnion support structure ensure smooth, stable operation in high-pressure, large-diameter applications.

Emergency Leak Protection

Features a sealant injection port for emergency seal leakage, enabling temporary sealing and minimizing operational losses during unexpected shutdowns.

Frequently Asked Questions

What does the top-entry structure mean and why is it beneficial?

The top-entry structure means the valve internals — including the ball, seats, and seals — can be accessed from the top of the valve body without removing the valve from the pipeline. This significantly reduces maintenance time and labor costs, enabling online repairs with minimal disruption to operations.

What safety features protect against hazardous environments?

The valve includes stem blowout prevention to stop the stem from being ejected under high pressure, electrostatic grounding to dissipate static buildup, and fire-safe backup seals that maintain integrity during a fire event.

How does the one-piece cast valve body improve performance?

A one-piece cast valve body eliminates the joints and flanges found in multi-piece designs, which are common leak points. This achieves greater structural integrity and long-term reliability in high-pressure applications.

What is the advantage of the trunnion support structure?

The trunnion-mounted ball uses mechanical anchoring at the top and bottom to fix its position. This reduces operating torque and wear on seats, making it ideal for high-pressure, large-diameter pipelines.

How does the sealant injection port work in emergencies?

It allows operators to inject sealant directly into the seat cavity when a leak is detected, creating a temporary seal to maintain operation until scheduled maintenance can be performed.

Are these valves suitable for offshore applications?

Yes. The combination of fire-safe seals, electrostatic grounding, and robust construction makes these valves well-suited for both onshore and offshore oil & gas and petrochemical environments.
