Features & Benefits
Safety
Integral bonnet provides differential thread pitch between stem threads and packing nut thread preventing accidental stem removal
Stem tip options
A choice of PCTFE, metal, vee-point, blunt vee-point, or regulating stem tips
Helps eliminate fugitive emissions
Dyna-Pak® packing provides a leak-tight seal with low operating torque in deep vacuum or high pressure applications
Dependability
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
Handle options
Color-coded handles are available for identifying system fluids
Panel mounting available
All models can be ordered for panel mounting
Easy maintenance
All models can be panel mounted without packing disruption. Packing can be adjusted without removal from panel
