Testimonial
The quality of this batch of shut-off valves is very stable, the sealing performance is excellent, and it fully meets our industrial standards. The logistics speed is also very fast, the packaging is strict, and there is no damage. The cooperation was very pleasant, and I will buy it again next time.
EngineerAmericaA very cost-effective type of stop valve. The price is much more affordable than our local suppliers, but the workmanship is not sloppy at all. It is tightly installed on the pipeline, and there is no leakage after running for a week. It is a trustworthy supplier.

- The applicable temperature of the ordinary carbon steel valve is -29°C ~ + 425°C.
- Alloy steel valve applicable temperature ≤550° C.
- 2.3.3 Stainless steel valves are suitable for temperatures from -196°C to +200°C.
Yes, we can recommend different material check valves according to your industry. For example, carbon steel valves are suitable for water, steam, oil, natural gas and other media; Stainless steel valves are suitable for corrosive media except carbon steel.
Storage, Maintenance, Installation and Use of Check Valve
The valve should be stored in a dry and ventilated indoor, and the valve channel should be blocked at both ends.
Valves stored for a long time should be checked and cleaned regularly. Special attention should be paid to the cleaning of the sealing surface and the prevention of damage to the sealing surface.
Before installation, the valve mark should be carefully checked to see if it matches the requirements of use.
Before installation, check the valve inner cavity and the sealing surface, and if there is any dirt, use a clean cloth to wipe it clean.
Before installation, check whether the packing is pressed tightly, and ensure that the packing is sealed, and at the same time, it should not hinder the rotation of the valve stem.
After installation, the valve should be in the fully open position when the system or pipeline is pressure-tested.
When in use, lubricant should be frequently injected into the taper thread of the valve stem. Manual valve, when opening or closing, should use the hand wheel to open and close, and should not rely on auxiliary lever or other tools.
Valves should be inspected regularly after use to check for wear on the sealing surfaces, valve stems, and gaskets and packing. If it is damaged and fails, it should be repaired or replaced in time.
