GROVE B5

The B5 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

• Antistatic device
• Bearing blocks that absorb the pressure load on the ball
• Body relief valve for overpressure due to liquid thermal expansion
• Bolted construction that permits disassembly in the field for repairs
• Built-in sealant injection system for emergency seat seal
• Double-barrier stem seals
• Double-sealing barrier in both directions
• Integral stop in the adapter plate for a permanent reference to open and closed position
• Large-diameter, short coupled trunnions that reduce unit bearing loads and operating torque
• Metal-backed, self-lubricating PTFE sleeve bearing and thrust washers that reduce torque and extend service life
• Nickel plating for trim parts
• Primary metal-to-metal seal and secondary protected synthetic O-ring seal
• Stem that is separated from the ball, delivering an antiblowout design
• Trunnion-mounted ball for ease of operation at high pressure
