Autoclave 30VM9081 Needle Valve
30VM Series: High Pressure Cone & Thread
Pressures to 30,000 psi / Larger Orifice and Higher Cv than 60VM Valves
Principle of Operation:
Since 1945, Parker Autoclave Engineers has designed and built premium quality valves, fittings and tubing. Our valves are designed specifically for use with High or Ultra High Pressure Fittings and Tubing for the most efficient flow path possible using Cone & Thread style connections. Designed in accordance with ASME 31.3 Chapter IX High Pressure Piping standards.
High Pressure Valve Features:
- Cryogenic or High Temperature Rated -423° to 1200°F with options
- Manufactured with UNS S31600 cold worked 316 stainless steel made to PAE proprietary standard
- Various designs cover valve sizes 1/4″ to 1” that use the “F” Series Connections (see Tools & Installation)
- 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
- For dependable stem and body sealing 30SC, 43SC, and 30VM valves are furnished with PTFE or PTFE glass packing; the 40VM and 60VM valves feature nylon/leather/nylon packing below threads and all can be used on liquids and gases
- Choice of Vee (Shutoff) or Regulating (Flow Control) stem tips available with optional N-Dura or Stellite material options for severe service

Notes:
- Parker Autoclave Engineers valves are complemented by a complete line of high 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 50%. (Based on water). Formula for converting Cv to volumetric flow can be found in 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.
