What is extension stem soft seal gate valve?

An extension stem soft seal gate valve is a type of valve that is designed to regulate the flow of fluids in a pipeline. It is called an "extension stem" valve because it has a longer stem than a regular gate valve, which allows it to be installed in deep and hard-to-reach places. 

The "soft seal" feature refers to the type of seal used in the valve, which is made of a soft material, such as rubber or plastic, that can conform to the shape of the valve seat, ensuring a tight seal and preventing leaks. This type of gate valve is commonly used in water treatment plants, sewage systems, and other applications where a reliable and durable valve is needed.

The gate valve does not need the valve well, which reduces the installation capacity and the embedded depth range can be adjusted. The telescopic rod is manipulated through the ground directly. The ground part and underground part are integrated into one, which can effectively prevent theft. The valve stem can be telescoped according to the depth of the valve well. The top of the stem is provided with a valve switch indicating that the signal remote transmission device can be installed, and the valve's wrong switch locking device can be installed.

Application:

Extension stem gate valves are commonly used in applications where the valve is installed in an area that is difficult to access, such as underground pipelines or buried valves. Some common applications include:

1. Water supply and distribution: 

Extension stem gate valves are used in water supply and distribution systems to control the flow of water. They are often installed in underground pipelines, and the extension stem allows the valve to be operated from above ground without the need for excavation.

2. Oil and gas industry: 

Extension stem gate valves are used in oil and gas pipelines for controlling the flow of crude oil, natural gas, and other fluids. They are often installed in offshore platforms, underground pipelines, or other hard-to-reach areas.

3. Chemical processing: 

Extension stem gate valves are used in chemical processing plants to control corrosive and abrasive fluid flow in pipelines, reactors, and other equipment. They are often installed in areas where it is difficult to access or where the valve needs to be isolated for maintenance or repair.

4. Mining: 

Extension stem gate valves are used in mining operations for controlling the flow of water, slurries, and other fluids in pipelines, pumps, and other equipment. They are often installed in underground pipelines or other hard-to-reach areas.

Overall, extension stem gate valves are well-suited for applications where the valve needs to be installed in an area that is difficult to access or where the valve needs to be isolated for maintenance or repair. They are widely used in many industrial processes and essential to pipelines, pumps, and other equipment.
