1. PRODUCT OVERVIEW
This two-piece trunnion-mounted ball valve is engineered for demanding isolation and flow control applications in oil & gas, petrochemical, chemical, power generation, and long-distance pipeline services. Featuring a robust two-piece bolted body construction with fixed ball trunnion design, it provides bidirectional bubble-tight shutoff, reduced operating torque, and extended service life under high pressure and large diameter conditions .
Key Design Features:
-
Two-Piece Bolted Body Construction: Robust body/bonnet bolted connection, suitable for high-pressure classes; options for ring gasket, spiral wound gasket, or lip seal ring .
-
Trunnion-Mounted Ball: Fixed ball design with lower trunnion support and upper anti-blowout stem; absorbs line pressure thrust, significantly reduces operating torque .
-
Double Block & Bleed (DBB) Capability: Standard design enables simultaneous isolation from both upstream and downstream, with cavity pressure relief and bleed functionality .
-
Dual Piston Effect (DPE) / Single Piston Effect (SPE) Seats: Flexible seat configurations available; Inconel®-energized springs ensure low-pressure sealing .
-
Fire-Safe & Anti-Static: Compliant with API 607/6FA and BS 5353; blowout-proof stem and anti-static device standard .

7. SEAT CONFIGURATION OPTIONS
| Seat Type | Configuration | Standard | Application |
|---|---|---|---|
| Double Piston Effect (DPE) | Both seats move to seal under pressure from either direction; cavity pressure self-relieving not automatic | API 6D DIB-2 | Bidirectional zero leakage; trapped cavity requires external relief |
| Single Piston Effect (SPE) | One seat moves to seal; opposite seat self-relieves cavity pressure | API 6D DIB-1 | Bidirectional; automatic cavity pressure relief |
| Mixed DPE/SPE | Upstream DPE, downstream SPE – or reverse | API 6D | Customized for specific flow/preferential sealing requirements |
| Metal-to-Metal | Hardfaced seats, no resilient insert | API 6D / 607 | High temp, abrasive, fire-safe |

Notes:
-
Torque values are estimated for soft seats (RPTFE) with clean service media.
-
Safety factors: Pneumatic actuators: 1.3 – 1.5; Electric actuators: 1.5 – 2.0.
-
Dry gas, viscous fluids, or slurries require higher torque multipliers; consult factory.
-
Metal-seated valves require significantly higher torque (2x – 4x soft seat values).
9. CAVITY PRESSURE RELIEF & DOUBLE BLOCK AND BLEED
Cavity Overpressure Protection:
-
Standard floating seat design in SPE configuration provides automatic self-relief of body cavity pressure to upstream pipe when cavity pressure exceeds line pressure by set margin .
-
DPE configuration does not self-relieve; external relief valve required.
-
Optional internal check valve in ball for thermal expansion relief .
Double Block & Bleed (DBB):
-
Valve design certified per API 6D for DBB functionality.
-
Body cavity can be independently vented via bleed valve while both upstream and downstream seats maintain seal against line pressure .
