P (NPT) Series Needle Valve: Pressures to 15,000 psi (1034 bar)

Principle of Operation

P Series (Pipe Style) Needle Valves are made available for those customers that prefer using pipe instead of high-pressure instrumentation tubing for pressures up to 15,000 psi MAWP. Designed using high tensile strength cold worked 316 Stainless Steel material and “ANPT” (Aerospace version - compatible with all ANSI B1.20.1 NPT connections) thread form. Use only with similar valves, fittings and pipe capable of same or lower pressures.

Notes: 316 SS valve bodies are cold worked and not suitable for use in NACE (ISO 15156)
applications. If required, contact factory for options.
* SOG suffix also changes CW 316 SS Body material to Annealed 316 SS suitable for
NACE service, Pressure reduction to 10,000 psi is typical.
*** Special Materials often have reduced MAWP ratings, see Technical brochure for
assistance and for additional material options

Valve Feature

 Pipe Valve Features

P Series valve design provides in-line pipe connections for 1/4" to 1" pipe sizes.

• UNS S31600 cold worked 316 Stainless Steel material as standard. See Technical brochure for
  additional material options.
• Non-rotating stem prevents stem/seat galling
• Metal-to-metal seating achieves bubble-tight shut-off, longer stem/seat life in abrasive flow, greater durability for repeated on/off cycles and excellent corrosion resistance. These valves can be used in liquid or gas applications.
• PTFE packing below stem threads provide dependable stem and body sealing. Optional packing materials available.
• Choice of Vee or Flow Regulating stem tips. N-Dura Coating or Stellite® material option for severe service
• Operating temperature range from -423° to 400°F (-252° to 204°C) (Limit of PTFE sealant tape)

 Valve Packing Options

Standard Parker Autoclave Engineers valves with PTFE packing may be operated from 0°F (-18°C) to 450°F (232°C). High and Cryogenic temperature packing and /or extended stuffing box are available for service from -423°F (-252°C) to 800°F (427°C) by adding the following suffixes to catalog order number:

• B Cryogenic trim materials and PTFE packing required when below 0°F (-18°C) to -100°F (-73°C)
• LT Extended stuffing box valve with PTFE packing and Cryogenic trim materials to -423°F (-252°C)
• TG Standard valve with PTFE-Glass packing -100°F (-73°C) to 600°F (316°C) (See also -B option above when below 0°F (-18°C)
• GY Standard valve with Graphite Braided Yarn packing 32°F (0°C) to 800°F (427°C).
