Enhanced technical reliability for pipeline transmission and storage applications
The API 6D fabricated gate valve in the GROVE valve portfolio meets market and industry demands for enhanced operational safety and reliability with reduced total cost of ownership. The large bore design ranges from 16” to 42” and includes the field-proven SLS spring-loaded lip seal technology, stem backseat, seat injection, and orientation flexibility as well as the option of nondestructively examined pressure-containing welds.

As a result, these GROVE valves help you

  • reduce product contamination with low internal volume
  • improve operational certainty through enhanced sealing integrity
  • save time and costs through inline repairability.

Enhanced fabricated body construction
The fabricated gate valve has an enhanced body construction in which all pressure-containing welds can be volumetrically and surface examined per American Society of Mechanical Engineers (ASME) codes.

Single SLS spring-loaded lip seal
The single SLS seal system optimizes performance while reducing maintenance requirements. The seal is hydrocarbon fugitive-emissions tested and fire tested as well as self adjusting, requiring no plastic packing to energize.

Stem backseat
The API Spec. 6D–compliant stem backseat serves as a secondary stem seal and retention device to prevent stem ejection. A metal-to-metal seal is created when the stem is in the up position, isolating the stem seal from line pressure.

Seat injection
Seats can be lubricated to reduce operating torques, effect a seal in an emergency situation, and promote long life.
