Key Features

Product Description

Key Features

Forged Body for Reliable Strength

The forged body construction provides high mechanical strength and pressure resistance, making the valve suitable for oil, gas, petrochemical and industrial pipeline applications.

Reduced Bore Trunnion Mounted Design

The reduced bore design helps optimize valve weight and installation cost, while the trunnion mounted ball structure improves ball stability under pressure and helps reduce operating torque.

Reliable Seat and Sealing Options

Devlon, PTFE, RPTFE and PEEK seats are available for standard industrial service. Sealing materials such as Viton GLT AED, HNBR, PTFE and graphite can be selected according to medium and temperature.

Sealant Injection for Emergency Sealing

Sealant injection design can support seat or stem sealing, helping improve field maintenance and emergency sealing capability in critical pipeline service.

Lockable Handle for Safer Operation

The valve can be equipped with a lockable handle to help prevent unauthorized or accidental operation in the open or closed position.

Flexible Configuration and Standard Support

Materials, seats, seals, pressure classes and end connections can be customized according to project requirements. API 6D, ASME B16.34, ASME B16.5 and API 598 standards can be followed, with MTC and test reports available.

Product Details

SLVCN forged reduced bore trunnion mounted ball valves are designed for oil, gas, petrochemical, chemical and industrial pipeline applications requiring reliable shut-off performance, stable operation and flexible material selection.

This valve series features forged body construction, reduced bore or full bore options, trunnion mounted ball design, sealant injection structure and lockable handle configuration. The trunnion mounted structure helps improve ball stability under pressure and reduce operating torque, while the lockable handle helps prevent unauthorized or accidental operation on site.
