描述
The P304 series gas cylinder valve is suitable for high-pressure, high-purity, corrosive, and toxic gases. It adopts a direct connected diaphragm type external seal to ensure that there are no small particles generated in the area where the gas flows through, aiming to ensure high purity of the gas. It has the characteristics of low leakage rate and large flow rate.
