The following article describes how to interpret the nameplates for the Honeywell control valves (now Hock control valves).
On this scheme you can see the factory provided nameplate for the Honeywell control valve series S600, series S800-30, series S800-14/20 and series S2000
Nameplate examples of different Honeywell control valve series:
Honeywell control valve type K21 now Hock series 2000 control valves
Honeywell control valve type A12 means series 600
Field 1: Flange and nominal pressure (Fl. / Rate)
- Nominal pressure dimensioned for the flange (Independent of the nominal pressure allowed by the body)
- Honeywell control valves without flange, butt welding nominal pressure of the body
Examples:
Fl. / Rate = ANSI 300 > Flange and body dimensiond for ANSI 300
Fl. / PN = 40 > Flange and body dimensiond for nominal pressure 40
Field 2 Type (Most important field to identify the control valve type)
- First, second and seventh digit of the specification number
- Type K21 = Honeywell control valve series S2000 (Today Hock Series 2000)
- Type A11 = Honeywell control valve series S600
- Type H21 = Honeywell control valve series S9000
- Control valves that do not have a specification number are identified by „custom“
Field 3: Characteristic curve and plug shapes (Cv)
e.g. Cv 47% C
