To meet the complete supply requirements for water treatment systems such as seawater desalination, our company has leveraged its technical advantages in valves, pipe fittings and related accessories to develop supporting components including check valves (non-return valves), integrated combination valves, dedicated pressure gauge connectors and high-pressure hoses.
The products are manufactured using advanced equipment and processes. The main wetted parts are made of corrosion-resistant materials, ensuring long-term service under highly corrosive and complex conditions such as seawater, industrial wastewater, concentrated brine and municipal landfill leachate.

Dedicated pressure gauge connector
Check valve
Check Valve：Designed for high-pressure and highly corrosive environments, the check valve utilizes imported duplex stainless steel, advanced equipment and processes, with a specially designed sealing structure that achieves reliable sealing at multiple leakage points. For the same valve structure, only the operating parameters of the elastic component need to be adjusted according to the working pressure to achieve flexible opening and closing, minimizing flow resistance loss caused by the valve.
Integrated combination valve
Integrated Combination Valve：Specifically developed for multi-functional and integrated systems, the integrated combination valve enables the integration and unified installation of liquid inlet/outlet ports, main control valve, test valve, safety relief valve, pressure and flow sensors, conductivity meter and other instruments. This simplifies the pipeline and valve installation for the integrated seawater desalination and firefighting system, reduces leakage points and lowers daily maintenance workload.
The main technical specifications of the check valve are shown in the table below:
| No. | Parameter | Value | No. | Parameter | Value |
|---|---|---|---|---|---|
| 1 | Nominal diameter (mm) | DN10~50 | 2 | Working pressure (MPa) | Up to 20 |
| 3 | Material | Duplex stainless steel | 4 | Proof test pressure (MPa) | Up to 30 |
| 5 | Applicable temperature range (°C) | 4~55 | 6 | Connection type | Threaded, grooved clamp |

Our high-pressure check valves offer the following competitive advantages compared to similar products:
Selected imported duplex stainless steel with superior corrosion resistance, manufactured with advanced equipment and processes – resistant to high pressure and corrosion in harsh environments such as seawater, industrial wastewater and landfill leachate.
Specially designed sealing structure and high-quality sealing materials ensure more reliable operation and longer service life.
Replaceable elastic components allow cost-effective and appropriate spring selection according to fluid properties and working pressure, ensuring flexible valve opening/closing and minimal local resistance loss.
Optimized valve chamber and disc structure further improve flow path and reduce pressure loss.
Our integrated combination valves offer the following competitive advantages compared to similar products:
Breaks away from conventional pipe welding assemblies – fewer leakage points, compact structure, neat and aesthetic appearance.
All valve components share a common fluid channel, resulting in low local resistance loss and more accurate measurement.
Fewer inlet/outlet ports, making installation, operation and maintenance more convenient.
Imported duplex stainless steel and imported seals provide corrosion resistance, long life and reliable sealing, suitable for various fluid environments.
Computer-aided design and manufacturing ensure good processability, rational material use and high cost-performance ratio.
