Description
This complete line of steel bodied valves with bolt-on
bonnets is designed and built to maintain reliability both in
the seating and back seating functions. This entire line is
supplied with stainless steel stems and backseating
capability. Corrosion resistant, high-grade stainless steel
trim is available upon request. A unique carbon filled PTFE
seat is standard throughout the line, lending durability to the
seating surface. In addition a dual O-ring stem packing
design along with a stem packing seal is standard on all
valves from 1/4" thru 12". This innovative design seals both
the valve stem and bonnet bore with independent O-rings,
which are captured in a carbon PTFE carrier. The addition
of the packing provides for backup sealing capability in the
unlikely event of an O-ring failure.

Trim Options
Standard mild steel trim includes Grade 5 Steel bonnet

The stainless steel trim option utilizes 316 Stainless Steel
bonnet bolts, packing nut and stem to provide corrosion
resistance for selected exposed parts.
Extended Bonnet
An extended bonnet is available for selected sizes and
styles of hand valves (see Availability Table). This design
supports 3" thick insulation above bonnet bolts for valves
through 3" size and 4" thick insulation for 4" size valves. All
extended bonnet valves incorporate 316 Stainless Steel
bonnet bolts, stem, packing nut, extension boss and boss
retainer.
Hand Expansion Valves
Hand expansion valves are the same as shut-off valves
except they feature a tapered plug for throttling action.
Handle options are a T-handle or seal cap.
