Customer Benefits

Reduced Noise Levels

The optional Lo-dB trim designs offer single-stage and double­stage noise attenuation benefits. Noise reduction levels of up
to 25 dBA are possible, depending on the specific operating
conditions.

Extended Life Cycle

Optional Anti-Cavitation trim is also available in single-stage
and double-stage configurations. Proper control of dynamic
cavitation conditions is extremely important for maintaining the
continuous high performance and reliability of control valves.

Lower Costs

Dependable tight shutoff of a control valve helps to reduce
the loss of process fluids, and can help eliminate the need for
separate isolation valves. The optional soft-seat design provides
bubble-tight shutoff capabilities in accordance with ANSI/FCI
and IEC requirements.

Clean Air Compliance

The optional LE Packing system helps to reduce atmospheric
emissions from the stem seal area. This unique feature helps to
promote compliance with environmental safety and emissions
control requirements.

Hazardous Emissions Control

The optional Bellows Seal configuration is well-suited for
applications involving highly toxic and dangerous fluids. Positive
sealing and extended life-cycle operation combine to promote
reliable and safe operation.

Low Temperature Operation

The 21000 Series from GE is also available in a cryogenic
configuration for effective process control performance at
extremely low temperature conditions. This is accomplished
by using a combination of extended bonnets and construction
materials.

LE Packing

The 21000 Series can be equipped with various Masoneilan
advanced digital positioners and controllers for enhanced
performance and control. This results in improved process yields
and real-time diagnostics capabilities to support predictive
plant maintenance programs. GE offers the Masoneilan SVI*
II AP (Advanced Performance) with HART® communications
and the Masoneilan FVP* for Foundation Fieldbus applications.
Both instruments are available in single- or double-acting
configurations and offer advanced control technology to provide
enhanced precision for pneumatically actuated control valves.
We also offer the Masoneilan ValVue* Software Suite for PC­based communications with these advanced devices..
