These installation and maintenance instructions apply to all
sizes and ratings of the 21009 Series control valves regardless
of the type of trim used.
21009 Series single ported Cage guided control valves are
designed with built in versatility making them well-suited to
handle a wide variety of process applications.
Standard construction offers a contoured plug (21109 Series)

provides maximum support to ensure plug stability.
A series of reduced area trim is available to provide wide flow
range capabilities in all valve sizes.
Tight Shutoff Class IV leakage is standard. Optional constructions
meet IEC 534-4 and ANSI/FCI 70.2 Class V requirements.
Recommended spare parts required for maintenance are listed
in the Parts Reference table on page 10. The model number,
size, rating and serial number of the valve are shown on the
