Cameron’s Valves & Measurement business segment is aleading provider of valves, valve automation, and measurement systems to the oil and gas industry.We provide large-diameter valves for use in natural gas,LNG, crude oil, and refined products transmission lines as well as in many other general industrial applications.Rigorously tested, field-proven, and backed by ourservices team, Cameron’s GROVE® valves are among thebest known valves in the world.
GROVE B4
The standard design valve code is B4.D.
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
GROVE B5
Double-barrier stem seals
Stem separated from the ball; anti-blowout design;no side load on the stem
Bearing blocks absorb the pressure load on the ball
Primary metal-to-metal seal and secondary protected synthetic O-ring seal
Double-sealing barrier in both directions (DPE)
Body relief valve for over pressure due to liquid thermal expansion
Built-in sealant injection system for emergency seat seal
Metal-backed, self-lubricating PTFE sleeve bearing and thrust washers reduce torque and extend service life
Nickel plating for trim parts
Trunnion mounted ball for ease of operation at high pressure
Large-diameter, short coupled trunnion to reduce unit bearing loads and operating torque
