Product Detail

The DIB-1 & DIB-2 Trunnion Mounted Ball Valve with Support Plate Structure represents the pinnacle of high-integrity isolation technology compliant with API 6D. Designed for critical applications requiring absolute shut-off, this valve offers customizable seat configurations using SPE (Single Piston Effect) and DPE (Double Piston Effect) seats to achieve DIB-1 (both seats bidirectional) or DIB-2 (one unidirectional, one bidirectional) functionalities. To handle the immense thrust generated in large-diameter and high-pressure services, the valve features a robust Support Plate Structure (or trunnion plate) that rigidly secures the ball and absorbs pipeline stress, ensuring smooth operation and extending seat life.

Design Description

Rigid Support Plate Design: Instead of the trunnion being supported solely by the body, heavy-duty plates hold the ball and bearings in place. This prevents ball deflection and uneven seat wear in large-bore, high-pressure operations.
Flexible DIB Configurations: Easily adaptable to DIB-1 or DIB-2 processing requirements based on specific pipeline safety philosophies.
Double Isolation and Bleed: Provides the ultimate safety barrier for maintenance personnel, allowing positive isolation of high-pressure lines.
Emergency Sealant Injection & Fire-Safe: Features secondary sealant backup and passes API 607 fire tests to ensure survival in catastrophic events.

Application & Function

DPE * SPE DIB-1 DIB-2 Ball valve With Support Plate Structure are widely utilized in demanding environments due to their superior material properties:

Custody Transfer Metering Skids: Where zero leakage is required to ensure accurate oil and gas measurement.
Product Manifolds & Pigging Stations: Providing reliable isolation for pipelines carrying multiple media or requiring frequent maintenance.
Critical Process Isolation: Refining and chemical units where toxic or high-pressure fluids must be safely contained.
