Description
Main Applications
– Liquefied natural gas process
– Shipbuilding
– Gas pipelines
– Gas storage facilities
– Process engineering -
Advantages
– Thermal insulation
- – The neck extension protects the actuator from cryogenic temperatures.
– The valve can be optionally protected in the system by a drip plate.– Perfect tightness
- – The plain bearings ensure outstanding shaft guidance. Triple sealing at the shaft passage meets the requirements for emissions performance in accordance with ISO 15848, Class AH (most stringent requirement).
– Tight shut-off in both directions ─ at ambient as well as cryogenic temperatures– Easy to install
- – Easier handling thanks to lifting lugs on the body
– Lip seal at the lower end of the neck extension facilitates installation in any position ─ even “upside down”.– Maintenance-free
- – No retightening of the cable gland
– Cover can be removed to check joint ring and valve disc.
– No special tools required to replace seal– Long service life
- – Wear-free seat
– End stops protect the seat and valve disc should the actuator not be properly installed. -
