CNG valve is a new type of safety equipment for gas storage and using engineering; it is used to cut off, connect and adjust the gas in the pipeline, with good control characteristics and closing and sealing performance; suitable for city gas, liquefied petroleum gas, natural gas, Oxygen, and other fuel gas medium pipelines. CNG valves can be applied to a variety of gases such as CNG, methane, ethane, and other similar gases. The valve body is made of high-quality forged brass, which can resist high pressure. So, what are the characteristics of CNG valves? Please let me introduce them to you in the following contents.
Here is the content list:

What are the characteristics of CNG valves?
CNG valve is a new type of safety equipment for gas pipeline engineering; it is used to cut off, connect and adjust the gas in the pipeline, with good control characteristics and closing and sealing performance; suitable for city gas, liquefied petroleum gas, natural gas, Oxygen, and other fuel gas medium pipelines. CNG valves are used for CNG, methane, ethane, and other similar gas services. The valve body is made of high-quality forged brass, which can resist high pressure. The innovative core design reduces the pressure in the internal area, thereby making the CNG valve highly safe. Generally, CNG valves can be applied from 0 psi to more than 6400 psi.
CNG valves certainly have lots of different types, in this passage, I will mainly talk about the CNG gate valve, which is one of the most common and popular CNG valves that are used nowadays. The CNG gate valve body adopts a casting structure. The valve seat adopts an O-ring seal and a floating seat structure with pre-tightening force applied to make the valve inlet and outlet two-way sealed; and the opening and closing torque of this structure are only 1/2 of that of ordinary valves, which can easily open and close the valve. The valve seat adopts the sealing surface inlaid with PTFE, which has a double seal of PTFE to metal and metal to metal, and the PTFE sealing surface simultaneously removes dirt on the gate. The gate of the valve, whether it is fully open or fully closed, is always consistent with the sealing surface, and the sealing surface is protected from direct erosion by the medium, thereby prolonging the service life. When the valve is fully opened, the passage is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss, and the pipeline can be cleaned with a hairball. When the valve is closed, the high pressure in the inner cavity can be automatically removed to ensure safe use. The closed gear rotation opening and closing indicator mechanism can clearly reflect the opening and closing conditions of the valve for a long time. The outer surface of the directly buried valve adopts epoxy coal tar anticorrosion treatment, which can have the same life as the pipeline
