Grove Valves
Grove Valves split-body side-entry ball valves are manufactured in a wide range of diameters and pressure classes, frequent-cycling, high- and low-temperature, corrosive demands of gas processing applications with increased safety and operational efficiency. Split-body construction allows the use of forged materials in various grades of carbon steel, stainless steel, and high alloys, equipping the valves for some of the most severe service conditions.

How Grove Valves work
- Seat Seals
The GROVE seat design ensures double-barrier sealing in both directions (the normal self-relieving seats are a simple barrier of sealing). The sealing is performed by both a primary metal-to-metal seal and a secondary protected O-ring seal. - Double Piston Effect (DPE)
The DPE seat design was invented and patented by Cameron’s GROVE team. The DPE seat design allows for both seats to seal with pressure acting from the same side of the valve. In the event one seat becomes damaged, the user has the added advantage of the opposite seat sealing. By means of this double barrier, the sealing is ensured regardless of the direction of the flow through the valve.
If the upstream seat (1) becomes damaged and leaks, the pressure entering the body cavity acts on the downstream seat (2), sealing the downstream seat tightly against the ball.
GROVE split-body side-entry ball valves B4,B5,B7
Applications
GROVE 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 reinjection units, offshore platforms, onshore terminals, pig traps, measuring stations, and surge-relief skids. These valves also can be built for specialty applications, such as subsea installations and LNG plants. Split-body construction allows the use of forged materials in various grades of carbon steel, stainless steel, and high alloys, equipping the valves for some of the most severe service conditions.
- GROVE B4
Features
-
- Double-barrier stem seals (the upper seal can be replaced with the valves in-line, under pressure, with the ball in the closed position)
- Short coupled trunnions reduce unit bearing loads and operating torque
- Factory-positioned external stops
- Stem separated from the ball; anti-blowout design; side load on stem
- Plastic polymer insert for seat sealing
- Self-relieving seats for ASME Classes 150 and 300
- Metal-backed, self-lubricating PTFE sleeve bearing and thrust washers reduce torque and extend service life
- Nickel plating for trim parts
- Fire-safe graphite rings for protection against external leakage
- The GROVE IST
The GROVE IST integrated seat technology ball valve meets and exceeds customer needs in critical applications—longer life span, small and lightweight footprint, high efficiency, and lower total cost of ownership.
The next evolution in trunnion-mounted ball valve design, the GROVE IST ball valve features a patented seat design that decouples ball flex and deformation from sealing performanceใ When pressure is applied to the valve, its integrated seat is energized, generating a reliable seal independent of ball deflection. While the valve is open, the patented spoiler in the counter seat diverts fluid and debris away from critical sealing areas, further increasing reliability The GROVE IST ball valve also features a top entry design for streamlined, simplified inline maintenance that reduces overall downtime
Features
