Specializing in the production valve external thread the needle valve, stainless steel threaded needle valve, J13W external thread the needle valve needle valve is a valve can be precisely adjusted, wider use, such as flame cutting with a cutting distance, adjust the flame temperature Knob is the needle valve. Instrumentation needle valve instrument measuring pipeline system is an important part of the main shut-off valve and ball valve, its function is turned on or off for the pipeline path available. Needle valve spool is a very sharp cone, it seems like the needle is inserted into the seat, hence the name.
