LIV Line 2 Needle Valves
Principle
LIV Line Needle Valve has 2 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
