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.
Improved Process Yields
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
