LIV Slimline Monoflange Valves
Principle
LIV Slimline Monoflange Valve with isolating valve
Construction
The valve body is machined from a round bar stock material.
The raw material of the valve can be supplied according to NORSOK
M 630 or to customer ́s specific requirements.
Inlet is a flanged connection, outlet 1⁄2” NPT.
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.
