, the internal atmosphere must be dry and
moisture free as bronze could be affected by carbonic acid.
These Globe Valves are supplied with stainless steel bodies (bolted
bonnet only) and bronze bodies (bolted bonnet and union bonnet)
extended and non-extended stems, with integral seat and
renewable PTFE disc, complete with bronze internals.
Available with socket weld and butt weld ends, sockets for copper
pipes and screwed female ends. The valve is of the cone seat
design for drop tight shut off. The bolted bonnet version allows
easy maintenance, even in confined spaces with lower bolting
torques required than for an equivalent size union bonnet valve.
The valve is operated by a hand wheel. The hand wheel is turned
clockwise to close the valve and anti-clockwise to open.
