Autoclave 15P6072 Needle Valve
P Series: NPT Threaded Connection
Pressures to 15,000 psi / Temperatures from -423F to +400F
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.
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 (Limit of PTFE sealant tape).

Valve Options (add the following suffixes to the valve part number):
- “B“: Cryogenic trim materials and PTFE packing required when below 0°F to -100°F
- “LT“: Extended stuffing box with PTFE packing and Cryogenic trim materials for temperatures to -423°F
- “TG“: Standard valve with PTFE-Glass packing -100°F to 600°F; see also -B option above when below 0°F; Parker does not recommend pipe connections for temperatures above 400°F
- GY“: Standard valve with Graphite Yarn packing for temperatures from 32°F to 650°F; Parker does not recommend pipe connections for temperatures above 400°F
- “PM“: panel mount; additional screw is supplied
- “SOG“: NACE material, hardness verification/certificate; changed body material from CW 316 SS to Annealed 316 SS suitable for NACE service; typically reduces pressure rating to 10,000 psi
Notes:
- Parker Autoclave Engineers valves are complemented by a complete line of low pressure fittings, tubing, check valves, relief valves and line filters.
- Traceability is ensured by use of heat and purchase order codes etched on valve body that also include model number, MAWP rating, and material type references.
- Cv values shown are for 2-way straight valve pattern. For 2-way angle patterns, increase Cv value by 50% (based on water). Formula for converting Cv to volumetric flow can be found in the Technical Information section of the catalog.
- NPT threads must be sealed using a high quality PTFE tape (3 wraps minimum) and/or thread sealant paste product suitable for process temperatures. Refer to thread sealant manufacturer’s instructions for application instructions. A good thread lubrication product (metal flake style) capable of process temperatures is also necessary to prevent thread galling.
- Sealing performance may vary based on many factors such as pressure, temperature, media, thread quality, thread material, proper engagement, and proper use of thread sealant.
- End user should limit the number of times an NPT fitting is assembled and disassembled as thread deformation during assembly will result in deteriorating seal quality over time.
