- G is the drill dimension of packing gland mounting hole
- G1 is the dimension of bracket mounting hole.
- Panel mounting drill size: 0.25" all valves.
- H is the dimension of stem in closed position.
- All dimensions for reference only and subject to change.
- Working Pressure: 30,000 psig (2068 bar)
- Working Temperature Range: -100°F~600°F (-73°C~316°C)
- Tubing sizes: 1/4”, 3/8” and 9/16”
- High tensile 316 Stainless Steel for valve body and 17-4PH Stainless Steel for lower stem
- Selected materials of packing gland and upper stem for optimum thread cycle life and reduced handle torque
- Metal-to-metal seating achieves ideal shutoff, longer stem/seat service lifetime for abrasive flow, excellent corrosion resistance and greater durability for repeated on/off cycles
- Non-rotating stem and bar stock body design
- Easy to assemble and replace packing
- Packing located under stem threads
- Reliable locking device for packing gland
- Options for Vee or Regulating stem tips
