DESIGN FEATURES

BOLTED CONSTRUCTIONAll SWI ball valve designs are of the split body bolted construction to facilitate ease of disassembly for maintenance purposes.

The double sealing action of the O-ring and fully contained graphite seals or Spiral Wound Gaskets design, ensures zeroleakage and fire safety assurance.

All bolting calculations satisfy the requirements of ASME B16.34. In particular, allowable bolt stress used in the body or bonnetjoints do not exceed the maximum value of either 7,000 or 9,000 psi respectively whichever bolt material is used.

The design complies with the requirements of ASME B16.34. Other codes (in particular ASME VIII Division 1) are only used asa supplement to ASME B16.34 for additional calculations not already covered in ASME B16.34.

SWI range of trunnion mounted and high pressure ball valve designs incorporate some of the most advanced features,including many major Owner & Operating Company specification preferences, whilst fully conforming to the designrequirements of API 6D & ASME B16.34 codes.

Trunnion mounted designs provide reliable sealing at the upstream or high pressure side through spring and pressure assisted

seats. The supported fixed ball has two independent spring assisted seat rings which are free to move along the valve axis

providing bubble tight and bi-directional sealing capability. The seal is formed by the seat ring assembly being pressure

energised against the ball as a result of the piston effect created by the fluid pressure. At low pressure, the sealing is

maintained by the force provided by the seat springs.

All these design features contribute towards the valves capability to provide the highest levels of performance and reliability,whilst ensuring repeatable shut off, positive sealing of all external leak paths and a high degree of safety for both plant andpersonnel.

SWI VALVE CO., LTD.

SELF RELIEVING FLOATING SEAT RINGS

Two independent single piston effect self relieving floating seat rings specially designed to minimize operational torque,ensure bi-directional tightness of the valve from zero differential pressure to the valves maximum rated pressure.

To retain adequate sealing in the event of fire damaging to the elastomeric primary seals, each is backed up by eitherEnergized Graphite or a metal to metal fire seal by way of the seat spring.

Destruction of the soft seat insert material will lead to the seat spring energising the metal seat ring to form a metal tometal seal a ainst the ball.

TRUNNION MOUNTED CONSTRUCTION

The trunnion mounted ball with its floating seat rings allows easy andsmooth operation even at high pressures. The differential load, producedby line pressure acting on the ball, is carried by the stem and trunnionbearings. These self lubricating, PTFE coated bearings maintain lowoperating torque and maximises service life.

POSITIVE CAVITY RELIEF

In the event of excessive pressure build-up in the body cavity (whilst the valve is fully open or closed) due to rapid

thermal expansion of the trapped fluid, the excess will be relieved to the pipeline as the seat spring is overcome on thelowest differential pressure side.

DOUBLE BLOCK & BLEED

SWI ball valve upstream and downstream positive sealing system allowsfor installation in services requiring a double block and bleed facility forbleeding of the cavity or checking of the sealing integrity in the open orclosed position.

When fitted, bleed valves or anti-blow-out vent & drain plugs may beopened to check seat integrity with the main valve in either the open orclosed position. Since there is no leak path from the pipeline to the bodycavity other than via the seats or seat seals, bleeding the body cavity willindicate any leakage.

Seat / seal integrity may therefore be checked PRIOR to affecting apipeline shutdown.

SWI VALVE CO., LTD.PRESSURE ASSISTED SEALING

The high pressure side seal is formed by the seat ring assemblybeing pressure energised against ball as a result of the single

piston action created by the line pressure.

SPRING ASSISTED SEALING

Live loading of the seat rings by springs assures sealing capabilityat low pressures.

STEM SEALING

Precision machining of the stem which is rigidly supported betweenbearings, combined with hardness control between metallic parts anddouble O-rings backed up by a secondary graphite seal, ensures reliableoperation with the highest levels of sealing integrity.

All seals can be replaced without the need to remove the stem from thevalve or remove the valve from the pipeline.

Designs incorporating PTFE / Inconel Lip Seals, high integrity mechanicallyenergised graphite or a combination of both, ensures sealing designssuitable for services from -196C + 200C (-320F to + 392F), includinglow fugitive emission control for VOC, Hazardous and Lethal serviceapplications.

ANTI-BLOW-OUT STEM

The stem is of a one piece bottom entry shouldered to body deign as standard.

No portion of the stem relies on any intermediate part of the body bonnet orcover or gland for its final positioning or anti-blow-out feature and the weakestpoint of the stem is outside of the pressure boundary.

These features ensure the stem drive train assembly is suitable for ESDapplications as standard.

EXPLOSIVE DECOMPRESSION

Wherever valves are used on high pressure gas applications, there is a possibility of gas being absorbed into the molecularstructure of elastomeric O-rings. If the valve is then subject to sudden decompression, the gas will expand rapidly and maydestroy the O-ring.

To eliminate this possibility, special O-ring seals or Lip seals, suitable for such service conditions are available.

SEAT & STEM EMERGENCY SEALANT INJECTION

Valves can be supplied with emergency sealant injectorsto the seat and stem seal area if required.

Special sealant is injected through fittings that are locatedbetween the double O-ring arrangement of the seat

assembly or stem seal area to restore sealing integrity.

Emergency injection facility is not available on valves inlow temperature service below -50C (-58F)
