V21000 Series single ported heavy top guided control valves are designed with built-in versatility, making
them well-suited to handle a wide variety of process applications.
Standard features include:
Rugged, heavy top plug guiding provides maximum support to ensure plug stability.
LO-DB/Anti-Cavitation Trim
Replacing the conventional plug with LO-DB design provides excellent noise attenuation or cavitation
control.
Reduced Capacity
A series of reduced area trim is to provide wide flow range capabilities in all valve sizes.
Pressure Drop Capability
A variety of actuator sizes to handle low to high pressure drop requirements.
Allowable pressure drop shown on all tables reflect actuator capability for the leakage class.
Proper application requires consideration with regards to cavitation, noise, velocity, etc. Refer to sizing
and noise manuals.
Tight Shutoff
Class IV leakage is standard. Optional constructions meet ANSI B16.104 Class V and VI.
Hardened Trim
Provided as standard to handle the high pressure drop capabilities of the V21000 Series.
Trim Type
Standard construction offers a quick change or threaded seat ring.
The following specification have been assembled to provide technical information required to specify
