High Pressure (coned and threaded) type connections for Tubing size from 1/4" to 9/16". Non-rotating stem and bar stock body design. 1. Easy to assemble and replace the packing Metal-to-metal seating achieves ideal shut off, longer stem/seat service lifetime for abrasive flow, excellent corrosion resistance, and greater durability for repeated on/off cycles. Nylon is the standard packing material, RPTFE glass and Graphite is also available. Extend stuffing box valves with Graphite can be operated to 1200°F (649°C). 2. The material of the packing gland and stem sleeve have been selected to achieve reduced handle torque and extended thread cycle life. 3. The material of the body is 316 SS, The material of valve stem is 17-4PH SS. 4. Options for Vee or Regulating stem tips. 5. The locking device of the packing gland is reliable. 6. Five flow patterns are available.
Notes： 1. The value of Cv shown is for a 2-way straight valve pattern. The value of Cv for 2-way angle pattern will be an increase of about 50 (Base on water) 2. Extreme Temperatures Nylon is the standard packing material for PESCO Needle Valve； RPTFE glass, Graphite, and Extend stuffing box valve with graphite
also available. Normal Needle valve with Nylon packing can be operated to 230°F (110°C). Normal Needle valve with RPTFE glass packing can be operated to 600°F (316°C). Normal Needle valve with Graphite packing can be operated to 800°F (427°C). Extend stuffing box valves with Graphite can be operated to 1200°F (649°C). Flow Data at 1OO°F (38°C).
