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.
