Product Details

Maximize Safety and Performance with Our Trusted Cylinder Valves


Our valve products mainly include the following parts: inlet thread, outlet thread, handwheel, model and safety device, etc. The main material of the product is brass, and some models of valves do not include handwheels and safety devices.
Our machining accuracy can reach<0.1mm, greatly reducing the possibility of air leakage during installation, and reducing costs for your steel cylinder production process. Our commonly used thread models include:pz27.8,25E,3/4-14NGT,G1/2,etc.The thread requirements for the air outlet are generally customized based on the pressure reducer you are equipped with. The requirements of each country vary, and the thread will also be different. If you have your requirements, I will customize them for you. Our commonly used thread models include:G5/8,G3/8,CGA320(0.825-14NGO),11/16-20TPI,etc. Our handwheel supports customization, including number of handwheel grooves,color,material, etc. You can choose the most suitable color and material according to the installed gas cylinder and usage scenario.
Production Process
The valve will be installed at the mouth of the steel cylinder during the production process, and there will be professional machinery to ensure the close connection between the valve and the steel cylinder, without any air leakage. The air outlet at the other end of the valve needs to be connected to a pressure reducer for use. During the installation of the pressure reducer, a wrench needs to be used to ensure that the pressure reducer is tightly connected to the valve.
