Our high-performance control valves are engineered to meet the demanding requirements of power generation facilities, turbine cooling systems, steam distribution networks, and renewable energy plants.
The global industrial valve market for power generation and energy is experiencing robust growth, driven by expanding electricity demand, aging infrastructure replacement, and the accelerating transition to cleaner energy sources.
Projected global control valve market size in the energy sector by 2028, growing at a CAGR of over 5.8%
Share of control valve demand attributed to thermal power, nuclear, and combined-cycle gas turbine plants globally
Increase in smart and automated valve adoption in energy facilities over the past five years
As global energy consumption continues to rise and power infrastructure modernizes, control valves have become indispensable components in ensuring safe, efficient, and reliable operations. From regulating steam flow in coal-fired power stations to managing coolant circuits in nuclear reactors, and from controlling hydraulic pressure in hydroelectric dams to optimizing fluid dynamics in solar thermal plants — control valves are at the heart of modern energy systems.
The control valve industry for power generation is evolving rapidly, shaped by digitalization, decarbonization mandates, and the push for higher operational efficiency across all energy sectors.
Integration of IIoT sensors, digital positioners, and predictive diagnostics enables real-time monitoring of valve health, position accuracy, and leakage detection — dramatically reducing unplanned downtime in power facilities.
The rapid scaling of wind, solar thermal, geothermal, and biomass energy systems is creating new demand for specialized control valves capable of handling variable flow rates, corrosive media, and extreme temperature differentials.
Ultra-supercritical (USC) and advanced ultra-supercritical (A-USC) coal power technology demands valves rated for pressures exceeding 300 bar and temperatures above 700°C, driving innovation in metallurgy and sealing technology.
New alloys, ceramic coatings, and PTFE-lined components extend valve service life in erosive, corrosive, and high-cycle environments common in power generation, reducing total cost of ownership significantly.
The proliferation of distributed energy resources (DERs) and microgrids requires compact, highly reliable valve solutions for small-scale combined heat and power (CHP) systems and energy storage facilities.
Tightening global regulations on fugitive emissions (EPA Method 21, ISO 15848) and pressure equipment safety (PED, ASME) are compelling power operators to upgrade to zero-leakage, certified valve assemblies.
TGV control valves are deployed across every major segment of the power generation and energy industry, delivering precision, reliability, and longevity in the most demanding conditions.
In coal, gas, and oil-fired power stations, butterfly valves and gate valves regulate main steam lines, feedwater systems, and condensate circuits. Precise flow control at high pressures and temperatures is critical for turbine protection and efficiency optimization. TGV's double-flange butterfly valves and resilient seat gate valves are widely used in these demanding applications.
Nuclear facilities require valves with the highest levels of seismic qualification, radiation resistance, and zero-leakage performance. Control valves in reactor coolant loops, emergency core cooling systems (ECCS), and spent fuel pools must comply with ASME III and IEEE standards. Stainless steel construction and PTFE seating are essential for these safety-critical environments.
Large-diameter butterfly valves and gate valves control water flow through penstocks, draft tubes, and bypass lines in hydroelectric dams. These valves must withstand high hydraulic pressures and water hammer effects while providing reliable shutoff and throttling for turbine protection and load management.
Concentrated solar power (CSP) plants use heat transfer fluids (HTFs) such as molten salt and synthetic oil at temperatures up to 600°C. Control valves in these systems must handle thermal cycling, high viscosity fluids, and stringent leak-tightness requirements. PTFE-seated and stainless steel valves from TGV are ideally suited for these applications.
CCGT plants integrate gas turbines with heat recovery steam generators (HRSGs), requiring precise control of natural gas fuel lines, cooling water circuits, and steam injection systems. Pneumatic actuated butterfly valves and check valves ensure rapid, automated response to load changes and emergency shutdowns.
The emerging hydrogen economy and large-scale battery energy storage systems (BESS) require specialized valves for hydrogen compression, electrolysis cooling, and thermal management. TGV's stainless steel and UPVC valve range provides excellent chemical resistance and leak integrity for these next-generation energy applications.
