Bolted Bonnet - Extended Stem and Non Extended Stem
DN6 - DN50 (1/4” - 2”)

Description
Stainless Steel extended and non-extended stem globe valve with bolted
bonnet, integral seat and renewable PTFE/PCTFE disc, complete with bronze
internals. Available with socket weld and butt weld ends, the valve is of the cone
seat design for drop tight shut off. 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 despatch.
