Structural characteristics of threaded valves

Threaded connection is a simple valve connection used for small diameter valves.It is different from other connections.

Threaded connection is a simple connection and is often used in small diameter valves. This connection is usually made by machining the inlet and outlet ends of the valve into taper or straight pipe threads that can be connected to taper pipe threaded joints or pipelines. Due to the potential for large leaky channels in this connection, sealant, sealant tape, or packing materials can be used to block these channels.

If the material of the valve body can be welded, but the coefficient of expansion varies greatly, or the range of working temperature is large, the threaded joint must be tightly welded. Threaded valves are primarily nominal sizes below 50mm. If the size is too large, it is difficult to install and seal the joint. To facilitate installation and removal of threaded valves, pipe fittings may be used where appropriate in the piping system.
