What is a GROVE Ball Valve?
The GROVE valve is constructed of forged components bolted together in a side-entry design. The standard designs are ideal for transmission and standard production operations. This design also allows for specialty configurations required in applications such as subsea installation and LNG plants.
Standard Features of GROVE Ball Valves
- Size range: 6” to 64”
- ASME Classes: 150 to 900
- Trunnion mounted
- Double barrier stem seals
- Stem separate from the ball
- Anti-blow-out stem design
- Stem emergency grease fitting
- Low friction metal-backed self-lubricating PTFE sleeve bearings and thrust washers
- Primary metal-to-metal seal and protected secondary O-ring seal
- Double-piston-effect seat rings (double sealing barrier in both directions)]
- Double-block-and-bleed
- Pressure relief valve in the body cavity to prevent pressure lock
- Sealant injection system for emergency seat sealing
- Factory positioned external stops
- Integral stop in the adapter plate for a permanent reference to open and closed positions
- Electroless nickel coating on pressure-controlling parts and stem
- CE marking (PED Directive)
Optional Features of GROVE Ball Valves
- Triple barrier stem seals
- Stem emergency grease fitting
- Self-relieving seat rings
- Plastic polymer insert for seat sealing
- PTFE spring energized lip seals for seat and stem sealing
- Metal-to-metal seat sealing
- SS or Inconel 625 overlay on sealing areas
- Explosive decompression resistant seals (std for Class 600 and higher)
- Anti-static device
- Fire safe in accordance with API 607
Standards Compliance of GROVE Ball Valves
Fire safe in accordance with API 6FA, BS 6755 Part 2
Applications of GROVE Ball Valves
The Split Body Side Entry Ball Valves are manufactured in a wide range of diameters and
pressure classes.
In the standard versions, the valves are specified for transmission pipelines, pumping, compression and re-injection units, offshore platforms, onshore
terminals, pig traps, measuring stations, and surge relief skids.
In the special versions, the valves are used for subsea installations and in LNG plants.
Split body construction allows the use of forged materials in various grades of carbon steel, stainless steel, and high alloys thus complying with the most severe service conditions.
