Product Description

Top Entry Ball Valve Banner

Product Description

SLVCN's 600LB Trunnion-Mounted Ball Valve is designed for high-pressure and high-temperature industrial applications. With a dual-drive system (electric actuator + manual worm gear), it ensures secure operation for automation and emergency control.

The top-entry design allows in-line maintenance without pipeline removal, minimizing downtime. The forged body and trunnion-mounted ball provide robust support for large-size, high-pressure systems.

Double Block and Bleed (DBB) ensures reliable isolation and pressure control, while the metal-seated design offers excellent wear resistance and long lifespan.

Fire-safe features with anti-static devices and anti-blowout stem guarantee safe operation in hazardous environments. Ideal for oil & gas, chemical processing, and offshore applications, where performance and safety are paramount.

Key Features

✓ Dual-Drive Operation for Optimal Control

Combines electric actuator automation and manual worm gear control, ensuring reliable operation in all conditions, including emergencies.

✓ Top Entry Design for Quick In-Line Maintenance
Allows for easy in-line inspection and maintenance without valve removal, reducing downtime and cutting maintenance costs.

✓ Trunnion-Mounted Forged Ball for High Stability

The forged trunnion-mounted ball ensures even pressure distribution, perfect for high-pressure and large-diameter pipeline applications.

✓ Leak-Free Bi-Directional Sealing

Bi-directional sealing with low-torque operation ensures reliable, leak-free performance even under extreme pressure and in critical environments.

✓ Fire-Safe Design for Hydrocarbon Service

Fire-safe construction ensures sealing integrity during fire exposure, meeting emergency isolation requirements for oil & gas and chemical services.

✓ Emergency Shutoff for Enhanced Safety

An integrated emergency shutoff feature guarantees safe, leak-free operation during critical situations, providing quick and secure response.
