Description:

In a fuel cell system, the liquid water generated by the stack reaction is usually discharged directly out of the system. In some specific operating scenarios (such as forklifts operating in warehouses, construction machinery operating indoors), water cannot be discharged to the ground at will, so it needs to be collected into a water storage tank and discharged in a centralized manner after the equipment travels to a designated location.

At this point, the drain valve at the bottom of the water storage tank undertakes the key task of quickly emptying the stored water. Unlike the heated drain valve on the water separator, the water storage tank drain valve has higher requirements for bore and drainage speed - it needs to complete drainage quickly at a large flow rate to reduce equipment waiting time.

The Yingjia Power YJCV series large-bore drain valve is developed precisely for this need. The YJCV series drain valve uses a pilot operated cartridge normally-closed valve structure. For the water storage tank fast drainage scenario, the 12mm large bore specification (Cv value 4.2) can empty the accumulated water in the water storage tank in a short time.

The product uses 304 stainless steel material, with a working pressure range of 0~5MPa, a working ambient temperature of -40~85C and a protection class of IP68, meeting the harsh vehicle environment requirements. The product has undergone special oil and grease removal treatment and is suitable for hydrogen-related application scenarios. The product has passed CE and ROHS certification. The product supports two rated voltages, 12VDC and 24VDC, with a working voltage range of 8~32VDC, and can work with continuous power. The connector model is DT06-2S.

Applications:

This product is widely used in the water storage tank drainage of various proton exchange membrane fuel cell (PEMFC) systems, specifically including:

• Fuel cell forklifts (need to operate in indoor scenarios such as warehouses, cannot drain at will)
• Fuel cell construction machinery (need to operate indoors or in specific areas)
• Hydrogen fuel commercial vehicles (heavy trucks, city buses, logistics vehicles)
• Hydrogen fuel passenger vehicles (sedans, SUVs)
• Stationary fuel cell power stations (backup power, distributed energy systems)
• Hydrogen fuel cell ships
• Fuel cell system test benches

Typical application position: installed at the drain port at the bottom of the fuel cell water storage tank; when the water storage tank level reaches the set value the drain valve opens, rapidly discharging the collected liquid water.

Typical application scenario: when forklifts and other construction machinery operate in indoor scenarios such as warehouses and workshops, they cannot discharge the water generated by the fuel cell reaction to the ground at will. The system first collects the water into the water storage tank, and after the forklift travels to a designated drainage area, the large-bore drain valve rapidly empties the water. The 12mm large bore design ensures rapid drainage and reduces equipment waiting time.

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: 10-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: What is the difference between the water storage tank drain valve and the water separator heated drain valve?
A: The water separator heated drain valve is mainly used to periodically and quantitatively discharge the water separated by the water separator, usually with a smaller bore (2.5~3.5mm); the water storage tank drain valve is used to quickly empty the large amount of accumulated water collected in the water storage tank, requiring a large bore and fast drainage speed (12mm bore).

Q5: What structure does the YJCV series drain valve use?
A: It uses a pilot operated cartridge normally-closed valve structure; it opens when powered and closes when unpowered.

Q6: What media is the YJCV series drain valve suitable for?
A: It is suitable for a variety of media such as hydrogen, nitrogen, oxygen, natural gas, air, water, methanol and liquid ammonia.

Q7: 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.
