Soft Seat Side Entry Trunnion Type Ball Valve
Trunnion Side Entry Ball Valves typical application is for gas or crude oil pipelines, larger sizes (up to 60 inches) and higher pressure classes (ASME 4500 or API 15000psi). Body construction can be two or three pieces for smaller sizes (up to 6” RB), three pieces for larges dimensions. Raw material can be either forgings or centrifugal castings. Wide range of materials: carbon steels, austenitic or martensitic SS, duplex-superduplex SS, nickel-based alloys. Bolted body as a standard, welded body for special applications (see specific section).
Valve main technical features include anti blow-out stem and valve seats design available in three different versions:
SPE (Single Piston Effect): the seat is energized by upstream pressure only .
DPE (Double Piston Effect): the seat can be energized by upstream pressure or by body cavity pressure .
DUAL (SPE upstream and DPE downstream): combining the two seat designs explained above, a double barrier can be assured in case of seat sealing failure

Sealing Options
Soft seat: Metal to Metal O-Ring seal
Simple structure reliable sealing Applicable to particulate Reliable sealing low torque meet customers' high
wide application low cost. media conditions sealing reliability and low torque requirements
Fire safe design
Ball valves ensures 100% pass of the fire safe test. As Ball valve applies two sealed design via O-ring seals and metal graphite spiral wound gasket. When the valve is on fire, non-metallic materials such as PTFE seat seals, gaskets ,O-ring seals,rubber etc will be damaged, meanwhile the outer layer of metal graphite spiral wound gasket provides a secondary seal. When the soft seat is burned, metal seat will automatically form a metal seal with ball under the urging of the spring which will effectively control the internal leakage and external leakage. Valve design fully accords with API 607, API 6FA, BS 6755, JB / T 6899 and other standards,
DOUBLE BLOCK & BLEED (DBB)
When the ball is in the closed position, each seat seals off the process medium independently at the same time between the up/down stream and body cavity, it allows bleeding the trapped cavity pressure (DBB) through drain and vent valve. The double block and bleed function make it possible to flush the valve under pressure and verify that the seat are sealing properly.
DOUBLE ISOLATION & BLEED (DIB)
Double piston effect seat, medium pressure, both upstream and downstream as well as in the body cavity, creates a resultant thrust that pushes the seat ring against the ball, valve with double piston effect seat rings require a cavity pressure relief to reduce the build-up of over pressure in the body cavity.
The ball is fixed by trunnion and stem for size 4” &smaller. Trunnion plate support for size 6” & larger
