Focus on Cost of Ownership

Improving Overall System Performance

• Operations understanding of existing upstream to downstream conditions

• Application Obsolescence- Technology was best available at the time are now misapplied

• Longer downtime • Increased Operation & Maintenance Costs

• ValvTechnologies Solution


Upstream • System components degrading due to over taxing the

components beyond design intended use • Makeup water loss

Downstream • Erosion/ corrosion of the downstream piping system

Operations affect • Lost inventory • Increased maintenance and downtime • Maximizing inefficiency

A Few Example Applications

9/5/2018 8

Metal Seated Ball Valves

Metal seated ball valves were introduced to address short comings of their soft seated counterparts.

MSBV’s incorporate a metal-to-metal seal between the seat and ball of the valve assembly.

Thermoplastic seals are usually recommended for clean service.

In MSBV’s the design of the seats and coatings are key determinates for valve to be used in abrasive, severe service.


Metal Sealing Technology

Zero-leakage metal area contact seal is difficult to achieve with a brand new valve

• Seat loading forces are distributed across a wider area • Wider seal areas create bigger potential leak paths

Zero-leakage metal area contact seal is much more difficult to maintain after installation & use BAT™ requires:

• Precision alignment of ball & seat • Precision sealing surface finish (for extended periods) • Restrict particles from getting between sealing surfaces

Comparison

Metal Seated Ball Valves • Both are quarter turn

designs that are suitable for on-off utility services.

• Incorporate a metal-to-metal seal between the seats and ball of valve assembly.

• MSBV’s use metal such as 316SS as seat material

Soft Seated Ball Valves • Have soft seat inserts

and use thermoplastic material such as PTFE.

• Thermoplastic seats are recommended for clean service, not suitable for abrasive, severe service.


Application Obsolescence

Globe & Gate Valves vs MSBV’s • 21st century technology versus 19th century • Throttle valves in isolation applications • Valves with exposed seats during flow expected to isolate • Linear torque seated versus position seated quarter turn • Hardcoatings versus hardfacing • Class IV – V versus Absolute Zero Leakage


Absolute ZERO Leakage


Does Isolation Matter?

Leakage: • Compromised safety • Reduces performance • Increases operating costs • Lost revenue • Major component damage upstream and downstream • Destroys performance guarantees: KPI’s

• Safety • Environmental compliance • Profitability


Absolute ZERO Leakage

Why is ZERO Leakage a Benefit?

•Zero Leakage = Long Term Reliability •Reduced Valve Maintenance •Warranty Repair/Replacement Eliminated

•VTI Overall Spare parts business represents < 1% of overall sales •Post Warranty Cost of Ownership Greatly Reduced

•Reliability: Reduction maintenance, parts , and excessive replacement costs caused by inadequate valve performance. •Personnel SAFETY enhanced by the elimination/reduction of maintenance. (ALARA)

•System Integrity Improvement •Elimination of thermal loss from process fluid migration across the seating interface… lost Megawatts

•Return on Investment: < 1 cycle ROI or less


Absolute Zero Leakage… = Reliability!

Valve Hardfacing Technology

• Wedge, plug and seats of carbon, alloy or stainless steel must be hard-faced on the sealing surfaces

• Stellite® VI weld overlay is commonly used for hardfacing of valve discs and seats

• Stellite® VI is a cobalt-chromium alloy, with good wear and corrosion resistance properties

RiTech™ vs. Stellite


RiTech™ HVOF Process

• RiTech is a high-velocity oxygen fuel (HVOF) coating process that delivers: • High density • Low porosity • Low friction • High corrosion resistance • Wear resistance

• HVOF hardcoating is excellent for extreme corrosion and wear resistance in many nuclear applications.


RiTech™ Performance Benefits

• Low substrate temperature < 300ºF (149°C) = No need for stress relieving • High strength mechanical bond (>25,000 psi) • Withstands thermal cycling without cracking • Low Coefficient of Friction .2 - .28 • Self-repairing in operation- “Wears in not out…”™ • Testing at 1,000,000 cycles performed – ZERO Leakage • The RiTech chrome carbide particles are harder than most (if not all)

particulate in a pipeline including all ferrites and magnetite. It resists any wear, scratching, galling and corrosion.

Typical hard-facings are susceptible to scratching or galling of the seating surfaces, especially at elevated temperatures. ANY damage results in LEAKAGE.

• Zero leakage metal to metal seal at all differential pressures

Summary Ball Valve - Designed for Isolation:

• Sealing Surfaces Always Protected • Undistorted Flow Path • Highest Possible Flow Capacity (through conduit) • QUARTER TURN for minimum wear on metal surfaces, stem packing, operating

devices

Globe Valve – Designed for Throttling: • Exposed Seating Surfaces when Open • Torturous Flow Path = Turbulence and Reduced Cv • Due to expected/allowable leakage, continuous seat degradation when valve is in

closed position • High Cost of Ownership

•V1-1 2“ (51mm) and smaller are Startup Steam Drains and Steam Trap Isolation

-These valves see 500°F / 260C steam with continuous pressure drops of 800 to 1000 PSI / 55 to 69 bar during the startup.

-They remain absolutely leak tight during the normal operation of the power plant –” these are truly zero maintenance valves”.

-Craig Johnson PSEG Engineering

•The globe valves replaced by VTI were source of continuous leakage, replacement and maintenance resulting in $125,000+ in annual savings = $2,500,000 and counting.
