Parker's Autoclave Engineer’s SM Needle Valves (SM Series)

Parker Autoclave's SM Series needle valves are designed with large ports for high flow applications. These valves have a non-rotating rising stem bar stock design with working pressures to 20,000 psi (1379 bar). The cone and thread connections utilize Parker Autoclave tubing with sizes from 1/4' to 1'.

316 stainless steel construction is the standard material with other options available.

Along with their many features these valves provide dependable and trouble free service in wide variety of applications.

Largest-port valves available for medium pressure applications.

Tubing sizes available from 1/4” to 1”.

Rising stem/barstock body design.

Non-rotating stem prevents stem/seat galling.

New one piece stem design permits ease of assembly and packing replacement.

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.

PTFE encapsulated packing provides dependable stem and body sealing.

Stem sleeve and packing gland materials have been selected to achieve extended thread cycle life and reduced handle torque.

Choice of Vee or Regulating stem tip.

Available in five body patterns.

EC-79 Certified

See our needle valves guide with all variants

The SM series needle valves are available in different variants. For details see our SM series guide - click here .

Introduction: 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.

Features: The Parker's SM Series Needle valve has been specifically designed for use with Medium Pressure cold worked 316/316L stainless steel tubing as standard

Materials: UNS S31600/ S31603, CW 316/316L Stainless Steel body construction as standard. See Technical brochure for additional material details

Pressure: Designed for a maximum of 20,000 psi MAWP using high tensile strength UNS S31600/S31603 cold worked 316/316L Stainless Steel material as standard, we include larger ID tubing rated to 15,000 psi (15SM valves) for even higher flow rate capability.

Stem: Most Parker Autoclave Engineers’ valves are available with either Vee (on-off) or Regulating (Flow Control) in our standard valve body seat or with our optional replaceable seat.

Options: Parker's SM Series Needle valve are available with different valve options a based on the user requirement as listed below.

Pneumatic Valve actuators: The need to control process and vent valves from a remote location makes air operated valves a vital component to many processing operations. Fore more details see the technical brochure.
Electric Valve Actuators: Parker SM series valve with The Electrically Actuated Shut-off/Flow Regulating Actuator (FRC Series) is available for most of our SM Series Valves through 9/16' tubing size and full working pressure. Fore more details see the technical brochure.
High / Low temperature Extension: High Temperature (Over 800°F (427°C)) and Low Temperature (under -100°F (-73°C))
ES Stem Extender: Stem extenders are offered for High and Low temperature operation or to extend through panel or barricade
Needle Valve Calm Shell Handle Lockout: Clam Shell Handle locks are provided to lockout valves in open or closed position preventing unauthorized personnel from actuating valve during shutdown or emergency situations.
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 1200°F (650°C) by adding the following suffixes to catalog order number, for more details refer the data sheet.
