Internal thread stop valve J11W-16P

The internal thread stop valve has the following advantages: simple structure, convenient manufacturing and maintenance.
The working stroke is small and the opening and closing time is short.
Good sealing performance, small friction between sealing surfaces and long service life.
,The disadvantages of the internal thread stop valve are as follows
The fluid resistance is large and the force required to open and close is large.
It is not suitable for media with large particle viscosity and easy coking.
The adjustment performance is better.
The types of internal thread stop valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight-through type and angle type. Globe valves are divided into sealing forms, including packing seal globe valve and bellows seal globe valve.
, Structural forms of internal thread stop valves
The structural forms of internal thread stop valve bodies include straight-through type, DC type and right-angle type. The straight-through type is the most common structure, but it has the greatest fluid resistance. DC fluid resistance is small and is mostly used for fluids containing solid particles or high viscosity. The right-angle valve body is mostly forged and is suitable for smaller stop valves with higher pressure.
