Valve Solutions for Your Industry
Different media, pressures, temperatures, and operating modes impose varying requirements on valve design, materials, and sealing solutions. Based on actual application conditions, FJZS provides corresponding valve products and selection support for applications such as oil and gas, oxygen, cryogenic, and liquefied gas.
Oil & Gas Solutions
We provide reliable shut-off and isolation valve solutions for oil and natural gas transmission and process pipelines, tailored to meet various pressure, temperature, and pipe diameter requirements.
Oxygen Solutions
We offer specialized valve configurations for industrial oxygen piping systems that take into account pressure ratings, material requirements, and safety shut-off needs.
Low-Temperature Solutions
Designed for low-temperature and cryogenic operating conditions, these valves feature valve structures and material configurations suitable for low-temperature environments, ensuring stable operation.
LPG & Tank Truck Solutions
We provide safety valves, emergency shut-off valves, and other products for the storage and transportation of liquefied gas, as well as for tank trucks and loading/unloading systems, to meet pressure protection and rapid shut-off requirements.
Valve Solutions for Your Industry
FJZS operates its own production facilities, including machining equipment and areas dedicated to component processing and product inspection. Building on a foundation in valve manufacturing, we produce and configure products according to their specific structures, materials, and operating conditions—rather than simply reselling products.
- Supports the production needs of products with different structures and specifications.
- Completes the manufacturing process in accordance with specific product structures and technical requirements.
- Reduces procurement and application risks.
- Covers products for special operating conditions such as oil and gas, oxygen, cryogenic environments, and emergency shut-off systems.
Not Sure Which Valve You Need?
Simply tell us your specific operating conditions, and we can help you further determine the appropriate valve type, material, and configuration based on the medium, pressure, temperature, pipe diameter, and application requirements.

Quality Is Not Just About Inspection Results — It’s About Verification at Every Key Stage
Pressure Testing
Inspections are conducted based on the specific valve model, pressure rating, and operational requirements, with a focus on verifying the condition of the valve body and pressure-bearing components to ensure a solid foundation for stable, long-term operation.
Specification Inspection
Prior to shipment, the valve’s nominal diameter, pressure rating, connection type, construction type, and critical dimensions are verified to ensure the actual product conforms to the technical requirements confirmed by the customer.
Material Verification
Materials for the valve body, bonnet, stem, and seals are verified against the order and technical specifications to ensure they are compatible with the service medium, temperature, and operating conditions.
Sealing Inspection
Inspections are performed on the valve seat, disc, and critical sealing areas to verify the valve’s closed position and sealing performance, thereby helping to reduce the risk of abnormal leakage during operation.
Frequently Asked Questions About Industrial Valve Procurement and Selection
If you are looking for an industrial valve manufacturer in China, the following questions can help you quickly understand our product range, selection process, and quotation procedure.
1. Why choose FJZS as your industrial valve manufacturer in China?
We not only provide standard industrial valves but also offer a wide range of products for special operating conditions. By integrating valve selection, materials, manufacturing, and inspection with actual application conditions, we help customers move beyond simply “finding a product” to “finding the right product for their specific operating conditions.”
2. How do I choose the right valve for my application?
Valve selection requires consideration of the medium, operating pressure, temperature, nominal diameter, connection type, and intended function. If you haven’t yet determined a specific model, you can simply provide the operating conditions, and we can help you narrow down the range of suitable products.
3. Can you supply valves for special service conditions?
Yes. Our current product range includes valves for oil and gas, industrial oxygen, cryogenic media, as well as liquefied gas and emergency shut-off systems. Specific materials and designs must be confirmed based on actual operating conditions.
4. Can you manufacture valves according to drawings or specifications?
We can evaluate product configurations based on the drawings, datasheets, or technical parameters you provide, including requirements such as nominal diameter, pressure rating, materials, connection types, and actuators. The final solution will be confirmed based on the specific product model.
5. What if I don’t know the valve model number?
That’s okay. Simply tell us the medium, pressure, temperature, pipe diameter, and required functions for the valve, and we can help you determine the most suitable valve type based on these basic operating conditions.
6. What information do you need for a quotation?
To receive an accurate quote more quickly, we recommend providing the following:
- Medium
- Pressure
- Temperature
- Valve Size
- Connection
- Material
- Quantity
If you have drawings or a datasheet, please send those as well.
