Two-Piece Forged/ Cast Steel Trunnion Mounted Ball Valve
Models: Flanged / Butt Weld, Reduced Bore / Full Bore

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 .
Low Fugitive Emission Packing: Live-loaded disc spring packing system; optional ISO 15848-1 compliance .
Full Traceability: Positive Material Identification (PMI) and EN 10204 Type 3.1 certification available.

SEAT CONFIGURATION OPTIONS

Seat Type	Configuration	Tiêu chuẩn	Ứng dụng
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

Ghi chú:

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).

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 .
