V1-1 Valves for Spray Water Applications

Product: V1-1
Location: Poland
Plant type: Lignite UNIT 470 MW - Supercritical
Industry: Power
Application: Spray water control

This plant's globe valves were failing continuously, resulting in control loss of the spray water and decrease in plant efficiency. Additionally, the globe valves’ stem packing was tearing, causing high-pressure, high-temperature water to be sprayed around the malfunctioning valves, creating a dangerous environment for operating staff. Learn how ValvTechnologies solved this customer's problem.

Lower Emission & Heat Rate Efficiency

Customer: Combined cycle power plant
Location: United Kingdom
Plant type: Fossil power
Products: V Series and IsoTech®

Severe service valve leakage significantly reduces a plant’s heat rate performance, because BTUs leak away, never reaching the turbine. By utilizing ValvTechologies’ V Series metal seated ball valves and IsoTech® parallel slide gate valves for vents and drains, steam and water leakage is eliminated, improving the plant’s thermal efficiency.

V1-1 Lowest Total Cost of Ownership

Industry: Power
Plant tyle: Power producer
Application: Attemperator block
Product: V1-1

A major US combined cycle plant experienced significant seat leakage with a competitor’s valve
that was installed in the attemperator block application of the plant. After just one year of service and multiple attempts to correct the issue, the faulty valve compromised the plants’ performance resulting in high maintenance
costs and poor reliability.

Reducing TCO with ValvTechnologies’ IsoTech® 

Product: IsoTech®
Location: Ontario, Canada
Plant type: Two-on-one combined cycle power plant
Industry: Fossil power
Application: HP steam-main steam stop

The plant had two main steam isolation PSG valves installed in this application. They were experiencing severe leakage when valves were required to isolate. From initial plant start-up, the frequency of valve maintenance of up to twice per year per valve. The cost of $40,000 per repair, was a particular concern for the plant.

ValvTechnologies' Specialties

Customer: Major Global HRSG OEM
Location: Europe
Plant type: Combined Cycle - Natural Gas (CCNG)
Products: Double V Series ball valve

O-C-I/mid-point flow (inching) valves in CCNG power plants function primarily during power
plant start-ups. This specific inching requirement is for the steam line condensate drain valve application. As the plant is starting up, the valves move into a “mid-point flow” position, mid meaning interim, not actual 50% position. Once the plant reaches the required temperatures/pressures, the valves continue the process in operating first in the modulating position all the way through to that of isolation/closed position.

Turbine Isolation & Isotech® Parallel Slide Gate Valves

Product: Isotech®
Location: USA
Plant type: Chemical

A US chemical plant using wedge gate valves leaked so severely that steam passed through the valves and into the turbine making it impossible to perform turbine maintenance repair. The plant would have to be completely shut down so that the turbines could be accessed. With each occurrence, the cost associated with shutting down the plant was several million dollars per shut down.
