External Thread Angle Stop Valve

The external thread angle stop valve is a valve with an external thread connection and an angle design. It is mainly used for flow regulation and cutoff of fluid in pipelines. Its unique angle structure enables the valve to control flow in different directions of the fluid pipeline, especially suitable for systems that need to save space or change the flow direction of the fluid. The external thread angle stop valve opens or closes the flow channel by rotating the valve disc to control the flow of the fluid.

Design and manufacturing: GB/T12224-2005 / JB/T7747-1995
Connection type: external thread welding
Structural features: conical cover; movable valve disc; right angle type
Valve inspection and testing: JB/T9092-1999

※ Main Features
Angle design
The valve body of the externally threaded angle stop valve adopts a 90-degree angle design, and the inlet and outlet pipes are connected at right angles. This angle design allows the fluid to change the flow direction while avoiding interference with the flow direction, which is suitable for occasions with limited space or complex pipeline layout.
External thread connection
Unlike the traditional internal thread connection, the connection end of the externally threaded angle stop valve adopts external threads and is usually connected to the pipe with internal threads. The design of external thread connection makes the installation more flexible and can adapt to different pipe sizes and requirements.
Valve body and valve disc
The valve body is usually made of corrosion-resistant materials such as cast steel, stainless steel, and copper to ensure the long-term stable operation of the valve under high temperature, high pressure or corrosive environment. The valve disc has a simple design and usually uses rubber or metal seals to ensure good sealing performance and durability.
Valve stem and handwheel
The valve stem drives the valve disc up and down by rotating, and is usually equipped with a handwheel or electric drive device to facilitate the operator to accurately adjust the flow.

※ Product Application
Water supply and drainage system
External thread angle stop valves are commonly used in residential, commercial and industrial water supply and drainage pipeline systems. They can accurately control water flow and ensure the normal operation of the water supply system. This angle design is particularly suitable in confined spaces or where the fluid flow direction needs to be changed.
Petrochemical Industry
In the petrochemical industry, external thread angle stop valves are used to control the flow of media such as oil and natural gas. Because this valve can adapt to high temperature and high pressure environments, it is widely used for flow regulation in pipeline systems.
HVAC System
In HVAC systems, external thread angle stop valves are used to regulate the flow of coolants or heating agents, control air flow and maintain stable system operation.
Food and Pharmaceutical Industry
For industries that require high hygiene standards, external thread angle stop valves use non-polluting materials to prevent contamination of fluids, especially in food processing and pharmaceutical industries.

※ 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.
