Card Sleeve Stop Valve

The ferrule stop valve is a stop valve that uses ferrule connection technology. It is mainly used for flow regulation and cutoff of fluids in pipelines. Different from traditional threaded or flanged valves, the ferrule stop valve uses a unique ferrule connection method, which makes the valve installation easier and faster, and is less likely to leak. The ferrule stop valve is usually used in medium and low pressure pipeline systems and is suitable for occasions with high connection requirements.

Design and manufacturing: GB/T12224-2005 / JB/T7747-1995

Connection type: ferrule

Structural features: conical cover; movable valve disc

Valve inspection and testing: JB/T9092-1999

※ Main Features
Ferrule connection
Ferrule connection is a major feature of ferrule stop valve. Ferrule is a special metal ring component that forms a seal with the pipe connection component by pressing the ferrule during installation. This connection method does not require welding or threaded nuts, greatly improving installation efficiency and maintaining good sealing during multiple disassembly.

Valve body design
The valve body of the ferrule stop valve is usually made of corrosion-resistant materials such as cast steel, stainless steel, and copper alloy, which is suitable for the circulation of various chemical media and can withstand certain pressures and temperatures.

Valve flap and valve seat
The valve flap and valve seat design is usually simple. The valve flap is made of sealing material, which can effectively prevent fluid leakage when in close contact with the valve seat, ensuring the safety of the pipeline system. The vertical movement of the valve flap can accurately adjust the fluid flow or cut off the flow.

※ Product Application
Oil and gas
Card sleeve stop valves are often used in pipelines in the oil and gas industry to control the flow of oil and gas, prevent leakage, and operate stably under high pressure conditions. Since the card sleeve connection can effectively prevent the loosening of the pipeline caused by vibration and external force, it is particularly suitable for the transmission system of oil and gas.

Chemical industry
In chemical plants, card sleeve stop valves are widely used in control systems for corrosive fluids such as acids, alkalis, and solvents. The valve material can be selectively customized according to the properties of the medium to ensure the safety of the system.

Food and pharmaceutical industry
Card sleeve stop valves are also used in the food and pharmaceutical industries, especially in pipeline systems with extremely high requirements for hygiene and cleanliness. Card sleeve connections do not require welding or threaded connections, which greatly reduces the contact area of ​​the joints and reduces the risk of contamination.

Water treatment industry
Card sleeve stop valves are also widely used in water treatment equipment, which can effectively regulate and cut off water flow to ensure stable operation during water treatment.

※ FAQ

What are the installation requirements for control valves?
The valve should be installed at the appropriate position of the pipeline to ensure that the flow direction is consistent with the direction indicated by the valve body; secondly, check whether the valve and its accessories are intact before installation to ensure that there is no damage; during installation, ensure that the pipeline connection is stable to avoid stress concentration and prevent damage to the valve; in addition, sufficient space should be provided for the valve to facilitate adjustment, inspection and maintenance; finally, the valve should be protected from excessive vibration or temperature, especially under high pressure and high temperature environments.

What are the common applications of temperature and pressure reducers?
Temperature and pressure reducers are widely used in many fields. They are mainly used in steam systems to reduce high-pressure steam to appropriate pressure to ensure safe operation of equipment. They are commonly used in power, fertilizer, food processing and other industries. They are also used in oil and gas pipelines, chemical production, pharmaceutical plants, etc. to ensure stable pipeline pressure and avoid system overpressure or excessive temperature. In addition, reducers are also used in HVAC, metallurgy and other industries to adjust the temperature and pressure of the fluid in the system to ensure the smooth progress of the process.

How to maintain medium and high pressure valves?
When maintaining medium and high pressure valves, first check the wear of key components such as valve body, valve seat, sealing ring and valve stem regularly. Clean the valve to prevent impurities from blocking and affecting operation. Check the operating performance of the valve to ensure flexible opening and closing without sticking. Check the sealing to prevent leakage and replace the seals if necessary. For valves that operate at high pressure for a long time, it is recommended to perform functional tests regularly to ensure their reliability under high pressure environment. In addition, check the connection parts of the valve to avoid looseness or leakage caused by vibration or corrosion.
