Description
The Mark 708 with bellows stem seals that eliminate fugitive emissions by surrounding the valve stem with a pressure-tight barrier, isolating the stem from the process fluid and preventing leakage to the atmosphere.
Features- Standard bonnet port for use in lubricating the packing for added protection against leakage, or for use as a detection port for monitoring potential fugitive emissions.
- Triple-ply bellows provides added strength and enhanced performance.
