Autoclave 15SM16081 Needle Valve
SM Series: Medium Pressure Cone & Thread
Pressures to 20,000 psi / Temperatures from -423F to +1200F
Principle of Operation:
SM Series Valves are designed specifically for use with matching orifice Medium Pressure Cone & Thread Fittings and Tubing for the most efficient flow path possible using Cone & Thread style connections. Designed for a maximum of 20,000 psi MAWP using high tensile strength UNS S31600 cold worked 316 Stainless Steel material as standard, we include larger ID tubing rated to 15,000 psi (15SM valves) for even higher flow rate capability.
Medium Pressure Valve Features:
- Temperature rated -423°F to 1200°F with associated packing/material options (see below)
- Designed for use with Medium Pressure cold worked 316/316L stainless steel tubing as standard
- 15SM Series Hi-Flow valves available in sizes from 9/16″ to 1-1/2″ (See matched-bore tubing)
- 20SM Series valves available in sizes from 1/4″ to 1″ (See matched-bore tubing)
- UNS S31600, CW 316 Stainless Steel body construction 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, greater durability for repeated on/off cycles and excellent corrosion resistance. These valves can be used with liquid or gas.
- PTFE packing below stem threads provides dependable stem and body sealing. Optional packing materials available.
- Choice of Vee (shutoff) or Regulating (Flow Control) stem tips
- Replaceable Seat Option available with Right Angle 2-way body style
- Optional N-Dura Stem and Seat coating or Stellite material option for severe service available
- Pneumatic Actuator options available

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 valve with PTFE packing and Cryogenic trim materials to -423°F
- “TG“: Standard valve with PTFE-Glass packing -100°F to 600°F; see also -B option above when below 0°F
- “GY“: Standard valve with Graphite Yarn packing 32°F to 800°F; included when when selecting HT option; limits pressure rating of larger valve sizes
- “HT“: Extended stuffing box valve with Graphite Braided Yarn packing to 1200°F; limits pressure rating of larger valve sizes; for full effect of high temperature on pressure ratings, see the Technical Information section of the catalog
- “K“: Anti-vibration collet/gland assembly (replaces standard gland)
- “SOG“: NACE material with hardness verification / certificate; also changes CW 316 SS body material to Annealed 316SS suitable for NACE service
- “HYG“: Hydrogen / Helium upgrade / seat testing
Notes:
- Parker Autoclave Engineers valves are complemented by a complete line of medium pressure fittings and tubing.
- 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.
- All valves include connection collar and gland nut unless requested otherwise.
- 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.
- Maximum Allowable Working Pressures decrease as temperatures increase – see pressure/temperature rating guide in Technical Information section of the catalog.
