Features & Benefits
Safety
Lock nut secures packing nut to prohibit accidental removal
Long cycle life
Packing below stem threads prevents fluid from contacting the stem threads.
Non-rotating hardened 17-4PH stainless steel, Monel® or replaceable PCTFE stem tip is combined with a hardened 450 stainless steel - or Monel® thread gland to reduce galling
Helps eliminate fugitive emissions
Dyna-Pak® packing provides a leak-tight seal with low operating torque
Reliability
All valves are tested for bubble-tight leakage at both seat and packing
Installation variety
Broad selection of male NPT, female NPT, and HOKE Gyrolok® fractional or metric tube fitting connections
Panel mounting
Panel mounting is standard on all models
