When your operations demand uncompromising fluid control, selecting the right solenoid valve is critical for maintaining system integrity and safety. Shanghai Power Plant Valve Factory Co., Ltd. (SDF) brings over five decades of specialized manufacturing experience. We deliver high-performance industrial valves engineered for heavy-duty, high-stress environments. Our automated fluid control solutions hold top-tier global certifications, including API 6D, EU CE, and ISO 9001/14001/45001. They are trusted across the power generation, oil & gas, and chemical processing sectors.
We differentiate our products by their ability to handle extreme operational parameters. Our automated fluid control solutions seamlessly manage extreme pressures up to 80.0 MPa (Class 4500). They also endure severe temperature fluctuations from cryogenic -196°C up to a blistering 1100°C. This ensures reliable performance where standard valves fail.
We offer a comprehensive portfolio of automated fluid control solutions designed to satisfy both technical specifications and industry-specific demands. Our categories are structured by operation mechanisms and extreme media handling capabilities. This ensures you find the exact match for your critical infrastructure.
Engineered for extreme pressure applications, our high-pressure solenoid valves confidently operate within Class 150 to Class 4500 ratings. These units feature robust body materials and advanced pressure seal designs that prevent leakage under immense stress. They are highly suitable for critical power plant operations and demanding chemical processing lines where pressure containment is non-negotiable.
Built to withstand severe thermal stress, our high-temperature solenoid valves utilize premium forged alloy steel and specialized sealing technologies. These valves can endure temperatures up to 1100°C. They are the premier choice for main steam applications, renewable energy plants, and high-temperature industrial fluid control systems.
Direct-operated models utilize electromagnetic force to directly lift the sealing element, making them ideal for zero-pressure differential environments. Because they do not rely on line pressure to function, they are exceptionally reliable for smaller line sizes and vacuum applications. Engineers favor these units for their rapid response times and dependable actuation.
Pilot-operated (or servo-operated) models are designed for high-flow and high-pressure systems. They use the system's internal line pressure to assist in opening and closing the main orifice. This mechanism allows for a more compact design and significantly improved energy efficiency. They are a staple in demanding industrial automation and large-scale fluid routing.
SDF’s heavy-duty solenoid valves are deployed across some of the world's most demanding industrial landscapes. We are a designated manufacturer by China's Ministry of Machinery Industry and the State Power Corporation.

To further elevate our precision manufacturing capabilities, SDF is currently investing 1 billion yuan in a state-of-the-art smart valve factory. This facility integrates intelligent manufacturing processes to deliver unparalleled product consistency, rapid customization, and continuous innovation.
Specifying the correct solenoid valve for high-stress applications requires a careful evaluation of your system's unique parameters. To ensure optimal performance and longevity, engineers must assess several critical factors before procurement.
| Selection Criteria | Key Considerations |
|---|---|
| Media Characteristics | Identify whether the fluid is corrosive, viscous, or particulate-heavy to determine the appropriate body and seal materials. |
| Operating Pressure | Verify the maximum and minimum pressure requirements. Ensure the valve matches your system's MPa or Class rating (up to Class 4500). |
| Temperature Range | Select materials capable of withstanding your operational extremes, whether cryogenic (-196°C) or ultra-high heat (1100°C). |
| Actuation Method | Choose direct-operated valves for zero-differential systems or pilot-operated valves for high-flow, high-pressure environments. |
If standard specifications do not meet your project requirements, SDF provides fully customized valve design and engineering solutions tailored to your unique operational challenges.
Our high-pressure models are engineered to handle extreme conditions, with pressure ratings up to 80.0 MPa (Class 4500). We rigorously test them to ensure zero leakage in demanding power generation and oil & gas applications.
Yes, SDF provides fully customized engineering solutions for extreme temperatures. We manufacture valves capable of operating in environments ranging from cryogenic (-196°C) up to ultra-high temperatures (1100°C).
Our valves are backed by comprehensive global certifications, including ISO 9001/14001/45001, API 6D, API 607, and EU CE marks. Additionally, we are a designated manufacturer with China's Special Equipment Manufacturing Licenses (Levels A1, A2, B).
Direct-operated models use magnetic force to directly open the valve, requiring no minimum line pressure. Pilot-operated (or servo-operated) versions use the system's line pressure to assist in opening. This makes them ideal for high-flow and high-pressure applications.
