LIV Line Needle Valves
Principle
LIV Line Needle Valve has 1 isolating valve
Construction
The valve body is machined from a rectangular bar stock material.
The raw material of the valve can be supplied according to NORSOK
M 630 or to customer ́s specific requirements.
The valve spindle thread is external to stuffing box.
The valve has back-seating and non-rotating valve tip
The dust covers are coloured for application indication (isolate, equalize)
The valves are designed for PED 97/23EC.
