Product Feature of High pressure gate valve

 

  • No pressure retaining body-bonnet flanges or bolting.
  • Forged structure for all pressure containing parts. Optimized design for thermal fatigue required for power plant where frequent start-ups & shut-downs are the must.
  • Flanged valves are provided with flanges integral to the valve body forging or full penetration welded.
  • Lighter weight design compared to bolted bonnet.
  • High quality packing for reliable tightness and low emission performance.

 

Applicable Standard

 

Design ASME B16.34
Inspection & testing API 598
Marking MSS SP-25
Rating ASME B16.34
Fugitive emission ISO 15848

 

Flexible Wedge Sealing Design
The flexible wedge is a one-piece, fully guided cast wedge with a central hub to allow the seating faces to move relative to each other, thus compensating for distortion of the body seats due to thermal expansion or piping loads. Seat ring and wedge seating face are set at a 9° angle from vertical to minimize sliding contact of the wedge and seat ring during opening and closing.

Wedging actions help effect a tight seal in low differential pressure services. Flexible wedge construction resists wedge sticking or binding in services where the valve may be closed when cold and opened when hot. Seating surfaces are hardfaced with Stellite®6 to provide high life cycle capability in very high differential pressure services.

 

Parallel Slide Design
The gate is a split design using two discs spring loaded and held together by a gate holder with a corrosion reservior spring to provide initial energizing when closed. The gate relies for seat tightness on the primary fluid pressure acting on the downstream seat. There is no wedging action or extra loading on the seats resulting in considerably lower operating torque. During closing there is a bevel on the bottom of the gate to guide it in between the seats and recompress the spring. Seating surfaces are hardfaced with Stellite®6 to provide high cycle capability in very high differential pressure services.
