 SM Series Needle Valve: Pressures to 20,000 psi (1379 bar)

 

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° to 1200°F (-252° to 650°C) with associated packing/material options

  • 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 and Electric Actuator Options available - see page 8 for more details

Traceability is ensured by use of heat and purchase order codes etched on valve body that also includes model number, MAWP rating, and material type references. All valves include connection collar and gland nut unless requested otherwise. Parker Autoclave Engineers’ valves are complemented by a complete line of Medium Pressure Cone & Thread fittings, tubing, check valves, relief valves, and line filters.
Note: SM Series fully replaces 20SC, 20SV, and 15SV Series. 15SM Series replaces 10SM Series. 20SM and 15SM repair kits are used to repair these valve types.
