"High Performance" Instrument Valves
TOPIC:
Many years of Instrument Valve product development and improvement have yielded design features
when combined in one unit provide a true "High Performance" Instrument Valve.
Stem threads are rolled (not cut).
This prevents galling and lowers operating torque. The work hardening which occurs during the roll threading process makes the rolled threads stronger and smoother. In addition, 316SS stems are chrome plated for additional galling prevention.
Teflon® and Grafoil® packing gland is adjustable while valve is in service.
Viton® o-ring stem seal with Teflon® back-up ring provides the ultimate low-torque operation.
Mirror stem finish burnished to a 16 RMS finish in the packing area enables smooth stem operation and extends packing life.
Packing below threads prevents lubricant washout, thread corrosion, and keeps solids from entering the thread area.
