The extended bonnet separates the packing from the cold zone. A guide sleeve at the bonnet base supports stem alignment and stiffness.
Cobalt-alloy hardfacing on the primary seat and backseat resists wear. A live-loaded gland maintains packing compression.
The gate-valve arrangement incorporates protection against abnormal pressure rise from trapped cryogenic liquid.
Major components receive deep-cold treatment and degreasing. A drip plate helps keep condensate out of the insulation.
On/off isolation in low-temperature process and transfer piping.
Shutoff duty in cryogenic air-separation systems.
Isolation of low-temperature ethylene process lines.
