Storage & terminal lines
Trunnion ball, gate and butterfly configurations for isolation, with manual or powered operation.
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.

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