Description:

In a fuel cell system, the hydrogen output by the hydrogen storage system, after pressure reduction, still enters the fuel cell system at a relatively high pressure (usually 10~25bar). This high-pressure hydrogen needs precise opening and closing control to ensure safe system operation. The medium-pressure solenoid valve (also called stop valve) is the core safety component undertaking this key task.

The HSQLDCF series hydrogen line solenoid valve is installed in the high-pressure hydrogen pipeline between the hydrogen storage system and the fuel cell system, with the rear end connected to precision control elements such as the proportional valve. Its main functions include:

Safety control during system operation: when the fuel cell system operates normally, the solenoid valve remains open, allowing high-pressure hydrogen to pass. When the system detects excessive hydrogen pressure, leakage or other abnormalities, the solenoid valve can close quickly at any time, cutting off the hydrogen supply and protecting the fuel cell system.

Safe isolation after system shutdown: after the fuel cell system shuts down, the solenoid valve closes automatically, isolating the hydrogen storage system from the fuel cell system and preventing hydrogen leakage during system shutdown, ensuring long-term parking safety.

The HSQLDCF series uses a pilot type structure design with a response time of only <=10ms, able to complete the opening or closing action in an extremely short time. The flow bore is 8mm/9mm, with a flow of up to 520L/min (air @ 1bar), meeting the hydrogen supply needs of high-power fuel cell systems. The maximum working pressure is <=25bar, covering the typical working pressure range of fuel cell systems.

The product offers multiple interface and configuration options, flexibly selectable according to customer needs. It uses NBR sealing material with a protection class IP67, meeting the harsh waterproof and dustproof requirements of vehicles. The operating temperature range covers -40C~90C, adapting to extreme climate conditions.

FAQ

Q1: Can you provide samples for testing?
A: Yes, we support sample orders for vehicle installation testing and performance verification, and also accept mixed-model sample orders.

Q2: What is the delivery lead time?
A: Sample orders usually take 5-7 working days; bulk orders (depending on order quantity) generally take 15-30 working days.

Q3: Is there a minimum order quantity (MOQ) limit?
A: There is no strict MOQ limit; 10-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: Why does a fuel cell system need a medium-pressure solenoid valve (stop valve)?
A: The medium-pressure solenoid valve is installed in the high-pressure hydrogen pipeline between the hydrogen storage system and the fuel cell system and undertakes two main safety functions: first, when the system detects excessive hydrogen pressure or leakage, it can close quickly at any time to cut off the hydrogen supply and protect system safety; second, it closes automatically after the fuel cell system shuts down to isolate the hydrogen storage system from the fuel cell system and prevent hydrogen leakage.

Q5: What is the maximum working pressure of the medium-pressure solenoid valve?
A: Maximum working pressure <=25bar.

Q6: What is the flow of the medium-pressure solenoid valve?
A: Flow 520L/min (Air@1bar).

Q7: What is the service life of the medium-pressure solenoid valve?
A: Service life >=1,000,000 cycles.

Q8: What is the protection class of the medium-pressure solenoid valve?
A: Protection class IP67, meeting harsh vehicle environment requirements.

Q9: How to handle product failures?
A: We implement a strict quality control system, with an out-of-factory defect rate below 0.2%. During the warranty period, small batches of defective products will be replaced with new ones in the next order; batch quality problems will be negotiated for repair or replacement to ensure customer rights.
