ValSpeQ selection refers to Qualified ISO packing.
ISO Certification requires packing qualified and certified by production test.
Glossary Packing Qualified Packing Certified
Explanation
A packing that guarantees performance in terms
of leakage as per qualification and endurance.
A qualified packing that pass factory
test.
Test Performed on a prototype.
Performed on production, in factory
on actual valve.
Test type
CC1 = 20000 Cycles, 2 thermal cyclings at Rating
Pressure using Helium Leakage measurement.
CC1, CC2, CC3 = 5 Cycles, at
ambient temp and 6 bars using
Helium Leakage measurement.
CC2 = 60000 Cycles, 3 thermal cyclings at Rating
Pressure using Helium Leakage measurement.
CC3 = 100000 Cycles, 4 thermal cyclings at
Rating Pressure using Helium Leakage
measurement.
Configuration Defined in ValSpeQ valve by valve To be added in ITP
Pricing Defined in ValSpeQ
Consult Factory for price (quantity /
lot / size / type / dependency)

Production Test definition

Control Valve Design Considerations
Dynamic Seal Interface
• Fine Stem Finish
• Insures Good Sealing & Minimizes Wear
Static Seal Interface
• Good Packing Box Finish
• Dependent on Packing Type
Complete Assembly Alignment
• Plug & Stem Sub-Assembly
• Guide Bushing & Packing Box
• Actuator Mounting & Connection

Dynamic Operating Factors
Flow Induced Forces
• Resultant Side Loads on Valve Plug
• Guiding Close to Throttling Section
(Avoid Cantilevering)
Mechanical Vibration
• Effective Guiding in Both Valve &
Actuator Assemblies
Valve Stem Size
• Larger Diameter Results in Higher
Friction
GE Confidential

Maximum Control Performance
Reduce Friction
• Controlled Alignment
• Low Friction Materials
• Prevent Over Tightening
• Minimize Stem Diameter
Key Benefits
• Tighter Throttling Control
• Less Deadband & Hysteresis
• Better Valve Response
• Reduced Maintenance
• Smaller Actuator Requirements

• No Foreign Particles
• Increases Packing Life

EPA Requirements
Fugitive Emissions Regulations
• 40 CFR Part 60
• Volatile Organic Compounds (VOCs)
– Accelerates Ozone Formation
– Results in Adverse Health Conditions
Control Valve Emissions
• Major Contributor to Plant Leakage (60%)
• Consent Decrees … require “Low-E” valves
Controlling Emissions
• Specifications … certifications
• LDAR – leak detection and repair programs
• Consent Decrees
GE Confidential

Customer Impact
Consent Decree (CD) – a legal agreement between
EPA and a company enforced by US DOJ.
• Typically $500M in fines … $20k per valve
• Enhanced monitoring … LDAR … fines for non
compliance
• Aggressive repair & Low-E specifications
• Selectively including all valves in program not just
VOC (steam, water)
Control valves typically exempt in CD … but customers are
proactively requiring compliance!

(1) AH tested by vacuum method
(2) BH & CH tested by vacuum or bagging method
(3) AH, BH, CH leak measurement can be volumetric
(4) AM, BM, CM tested by sniffing method
