3'' Full Bore Forged Trunnion Ball Valve 5000 PSI

Product Introduction

The 3″ Full‑Bore Forged Trunnion Ball Valve 5000 PSI is a heavy‑duty quarter‑turn shut‑off valve designed for critical pipelines and process systems where reliability, performance and long service life are essential. The full‑bore design (also called full‑port) ensures that the internal ball opening matches the pipe bore size to minimise pressure drop and allow pigging or full flow. The trunnion‑mounted ball design anchors the ball at the top and bottom to absorb forces and maintain tight sealing under high‑pressure conditions. Forged body construction provides superior mechanical strength and integrity for high‑stress environments.
This valve is ideally specified for demanding industrial services where 5000 PSI (≈345 bar) class is required — for example in oil & gas, petrochemical, power generation, pipeline transmission and offshore installations.

Key Features

• Full Bore Industrial Valve – The full-bore ball matches pipeline diameter to minimize pressure drop and allow pigging.

• Forged Steel Construction – Provides superior strength, mechanical integrity, and high pressure resistance.

• Trunnion Mounted Ball Valve – Reduces seat load, lowers torque, and maintains tight sealing under 5000 PSI conditions.

• Double Block & Bleed (DBB) Capability – Ensures independent isolation of upstream and downstream flow with cavity venting.

• Fire-Safe and Anti-Static Design – Complies with API 607/6FA standards, preventing stem blow-out and static discharge.

• Low Operating Torque – Optimized seat and trunnion design reduce actuation force, suitable for manual, gearbox, pneumatic, or electric operation.

• Multiple End Connections – Flanged, butt-weld, and socket-weld options according to ASME B16.5/B16.47.

• High-Performance Seats & Trim Options – Supports corrosive, sour, cryogenic, and high-temperature service.

• Cost-Effective Flow Control – Full-bore design minimizes pressure drop and energy loss in pipelines.

Frequently Asked Questions

Q1: What is a 5000 PSI Ball Valve?
A: A 5000 PSI Ball Valve is a high-pressure valve rated for up to 5000 PSI, designed to provide reliable shut-off and flow control in industrial pipelines, including oil & gas, petrochemical, and power generation systems.

Q2: What does “trunnion-mounted” mean?
A: In a Trunnion Mounted Ball Valve, the ball is supported at the top and bottom (trunnions), reducing seat wear, lowering actuation torque, and enabling high-pressure operation with minimal leakage.

Q3: What is DBB capability and why is it important?
A: Double Block & Bleed (DBB) Ball Valves provide independent upstream and downstream isolation with a cavity vent, improving operational safety during maintenance or pipeline shutdowns.

Q4: Can it handle sour or corrosive media?
A: Yes, with appropriate material selection such as duplex or super duplex stainless steel and fire-safe seals, it is suitable for H₂S, sour, or corrosive service.
