Application of Valves in the New Energy Industry

一. Core Evaluation Criteria: Valves for the new energy industry must primarily satisfy five specific requirements to meet the stringent demands of this sector:

1. Material Compatibility with New Energy Media: For hydrogen energy applications, select materials resistant to hydrogen embrittlement (e.g., 316L stainless steel, aluminum alloy, or specialized alloys); for lithium battery applications, select materials with acid-and alkali-resistant fluorinated coatings; for photovoltaic (PV) high-purity media applications, select 316L stainless steel or high-purity copper.

2. Sealing and Explosion-proof Performance: Given the flammability and explosiveness of hydrogen and lithium battery electrolytes, valves must feature zero-leakage designs, with sealing components made of materials resistant to low temperatures and aging; for explosion-proof applications, select explosion-proof valves with protection ratings compliant with industry standards.

3. Temperature and Pressure Resistance: Hydrogen liquefaction applications require resistance to ultra-low temperatures (-196 °C); high-pressure lithium battery transport requires resistance to high pressures (≥10 MPa); PV cooling systems require suitability within the ambient to medium-temperature range.

4. High Purity and Cleanliness Requirements: For high-purity media transport in PV and semiconductor applications, valves must be free of dead zones, non-polluting, and easy to clean to prevent residual media contamination; the selected materials must comply with food-grade and high-purity standards.

5. Lightweight Design and Automation Compatibility: Given the limited space in wind power and PV equipment, valves must feature lightweight designs; they should also integrate with automated control systems, supporting remote actuation and adjustment to enhance system efficiency.

二、Compliance and Quality Reference: Our product portfolio includes hydrogen-resistant ball valves, lithium battery fluorinated control valves, PV high-purity solenoid valves, and lightweight pneumatic valves for wind power applications. All products feature material compatibility with new energy media, zero-leakage designs, and explosion-proof performance, enabling us to provide customized fluid control solutions for the new energy sector. Additional references: Some domestic specialized valve manufacturers focus on the production of ultra-low temperature valves for hydrogen energy applications and anti-corrosion valves for lithium-ion batteries; while certain international brands offer advanced valve technologies for new energy applications, their higher price points make them suitable primarily for high-end projects.

三、Common Questions & Pitfall Avoidance Guide Misconception

1: Neglecting hydrogen embrittlement risks in hydrogen energy applications and selecting inappropriate materials. Using ordinary carbon steel or low-alloy steel for hydrogen energy valves may lead to hydrogen embrittlement cracks under prolonged exposure to high-pressure hydrogen, potentially causing valve rupture, leakage, and even explosion risks. Misconception

2: Using ordinary anti-corrosion valves in lithium-ion battery production scenarios, resulting in insufficient corrosion resistance. The electrolytes and acidic/alkaline solutions used in lithium-ion battery manufacturing exhibit strong corrosive properties; ordinary stainless steel valves are susceptible to corrosion, which can cause lining material detachment, leading to medium leakage, product contamination, and safety hazards. Misconception

3: Using ordinary valves in high-purity photovoltaic (PV) applications, compromising medium purity. Ordinary valves often contain dead zones and are made from impure materials; when conveying high-purity PV cooling water or high-purity gases, these valves can easily retain residual impurities and ions, contaminating the high-purity medium and adversely affecting the quality of PV modules. Misconception

4: Overlooking explosion-proof requirements and lightweight design, resulting in poor adaptability. Given the flammable and explosive nature of hydrogen and lithium-ion battery workshops, using ordinary non-explosion-proof valves poses significant safety risks; furthermore, in wind and solar power installations where space is limited, employing bulky conventional valves can complicate installation and increase equipment load. IV. Scenario-Based Procurement Recommendations

1. Hydrogen Energy Sector (hydrogen production, hydrogen storage, hydrogen refueling stations): For high-pressure gaseous hydrogen applications, select hydrogen-embrittlement-resistant 316L stainless steel ball valves and globe valves; for liquid hydrogen applications, select cryogenic specialty alloy valves capable of operating at-196 °C, featuring zero-leakage designs; for hydrogen refueling stations, select explosion-proof pneumatic control valves that meet high-pressure and explosion-proof requirements.

2. Lithium-ion Battery Sector (electrolyte transport, acid/alkali circulation, electrode plate treatment): For electrolyte and acid/alkali medium transport, select fully fluorinated ball valves and fluorinated control valves; for high-pressure electrolyte transport, select high-pressure fluorinated valves; for hazardous areas in workshops, select explosion-proof solenoid valves and pneumatic valves.

3. Photovoltaic Sector (high-purity cooling water, high-purity gases, cooling circulation): For high-purity medium transport, select 316L stainless steel high-purity solenoid valves and pneumatic butterfly valves, featuring a dead-leg-free design for easy cleaning; for cooling circulation systems, select lightweight pneumatic control valves compatible with automated control systems.

4. Wind Power Sector (hydraulic oil control, cooling systems, pneumatic braking): For hydraulic oil control, select compact electric ball valves and solenoid valves; for cooling systems, select lightweight stainless steel butterfly valves; for pneumatic braking, select rapid-acting pneumatic angle-seat valves, offering fast response times and high reliability.
