The cylinder check valve is one of the most important safety devices in pressurized gas systems, and is installed on the gas cylinder opening. This valve not only controls the flow but also protects the cylinder against sudden pressure rise. Akhavan Kalantari Company, as the producer and supplier of medical and industrial gases, also provides standard cylinder check valves for CO2 and some industrial gas cylinders, according to the needs of workshops, industries, and specialized centers. This product is designed for installation on 5, 10, 20, 40, and 50 L cylinders, and is safe and reliable for sensitive and professional environments.
What is a check valve and its Application?
A cylinder check valve is a special valve for pressurized gas cylinders that has a relief check valve in its structure. This check valve activates automatically when the pressure inside the cylinder rises above the pressure limit, and purges a part of the gas from a safe path to prevent bursting or any other possible damage. This valve type is mostly installed on CO2 gas cylinders used in the beverage industry, welding and cutting, cafes, coffee shops, and some other industrial and laboratory applications. In some places with temperature and pressure fluctuations or high risk of operator fault, using a cylinder check valve plays an important role in risk reduction and safety improvement of the system.
Differences Between a Cylinder Check Valve and a Simple Cylinder Valve
At first glance, both valves cut, open, and control the gas flow, but the main difference is in the check valve:
Simple cylinder valve: only enables opening or closing the gas flow path and is not suitable for applications where the system pressure must be under control or the risk of sudden pressure rise is low.
cylinder check valve: In addition to the normal operation of a simple valve, this valve is equipped with a relief valve that prevents damage to the cylinder and other equipment by controlled purging a part of the gas when the cylinder pressure rises above the design pressure.
Technical specifications of cylinder check valves of Akhavan Kalantari Company
Check valves provided by Akhavan Kalantari Co. have the following technical specifications:
• Body material: high-quality brass, resistant to pressure and corrosion
• Inlet and outlet threads: according to DIN477 standard for compatibility with the common CO2 cylinders
• Working pressure: 170 bar, suitable for CO2 pressurized cylinders
• Installation: can be installed on CO2 gas cylinders with 5, 10, 20, 40, and 50 L capacity
• Applications: suitable for the beverage industry, industrial workshops, welding and cutting equipment, and other CO2 consumers. The special design of these valves enables their smooth opening and closing while they have a good strength and durability and can be connected safely to a manometer and other controlling equipment.
Role of Check Valve in CO2 Cylinder Safety
In this cylinder type, a check valve is mounted to prevent possible dangers of pressure rise beyond the upper limit. When the valve opens, it prevents undesired pressure rise in the cylinder that may result in the cylinder bursting. In practice, the relief check acts as a safety guard; when the pressure exceeds the limit, it opens the emergency outlet and reduces the pressure to a safe level.
