Cryogenic Valve
Cryogenic Globe Valve
Cryogenic globe valve with extended bonnet for accurate flow control in LNG, LPG, and air-separation service.
Inquire NowProduct Overview
The cryogenic globe valve is designed for accurate throttling in low-temperature service. Its extended bonnet isolates the packing from the chilled fluid, while the precision-ground disc and seat provide tight shutoff and stable flow control over wide operating ranges.
The valve is the preferred throttling solution for cryogenic process lines where pneumatic or electric actuators are used to modulate flow.
Key Features
- Extended Bonnet: Long neck keeps the packing above the cryogenic zone
- Precision Trim: Ground disc and seat for accurate flow control
- Repackable in Service: Top-entry design allows packing adjustment without valve removal
- Cryogenic Rating: -196°C service with BS 6364 / EN 1626 certification
- Multi-Actuator: Compatible with pneumatic and electric actuators
