Description

Stainless Steel Extended and non-extended stem globe valve with bolted bonnet and available with socket weld and butt weld ends, the valve is of the cone seat design for drop tight shut off. Unique Bestobell loose flange bolted bonnet design allows for thermal expansion and contraction and eliminates leakage at the bonnet gasket.

The bolted bonnet allows easy maintenance, even in confined spaces with lower bolting torques required than for an equivalent size union bonnet valve.

All valves are degreased for oxygen duty, assembled in clean room conditions and pressure tested prior to dispatch.
Limit switches available for position indication.


Maximum Working Pressure (MWP)

(Subject to End Connections)
Extended stem – 50 Bar (725 psi) at -196˚C to +65˚C
Non-extended stem – 50 Bar (725 psi) at -20˚C to +65˚C
