LNG

Cryogenic valves for LNG.

From a terminal transfer line to a compact distribution skid, the valve has to fit the process, the pipework and the operating sequence.

Illustrative application setting. Project arrangements vary.

The application

Follow the LNG through the system.

LNG installations combine cold liquid lines, vapour circuits and equipment that must remain accessible for operation and maintenance. Large-bore isolation, pressure control and non-return duty call for different valve constructions. We help define those duties from the line specification and operating cases.

01

Storage & terminal lines

Trunnion ball, gate and butterfly configurations for isolation, with manual or powered operation.

02

Transfer & distribution

Emergency shut-off valves, charging assemblies and release equipment for the selected transfer interface.

03

Flow & backflow control

Modulating globe assemblies and check valves selected for flow, differential pressure and operating response.

Selection essentials

What defines the right configuration?

Process
Liquid or vapour phase, design temperature and pressure at each operating case.
Connections
Line size, wall thickness, weld preparation or flange rating and facing.
Operation
Available utility, closing time, fail action and position feedback.
Documentation
Required tests, material traceability and project inspection plan.
