Features
- Long-neck bonnet design: bonnet neck extended to reduce cold transmission to operating mechanism and prevent packing from freezing; neck length calculated based on thermal conductivity and heat dissipation coefficient of material to ensure packing box bottom temperature remains above 0 °C
- Anti-abnormal-pressure-rise structure: pressure relief hole on inlet side of gate plate allows cavity pressure to vent, preventing gate plate from being locked against seat
- Gate movement perpendicular to fluid flow direction
- Two wedge-shaped sealing surfaces; wedge angle varies with valve parameters
- Full-open and full-closed service only; no throttling or regulation
Notes
- NPS 1/2* ~ 24* (asterisk notation as stated on page)
- Operator options listed as 'Manual, Pneumatic, Electric, etc...'
Description
A cryogenic gate valve designed exclusively for fully open or fully closed service; throttling and flow regulation are not possible. The opening and closing element is a wedge-shaped gate that travels perpendicular to the fluid flow direction. The valve incorporates a long-neck bonnet to prevent cold transmission to the operating mechanism and an anti-abnormal-pressure-rise relief hole on the inlet side of the gate.
