Stainless steel globe valve J11W stainless steel screw-type shutoff valve B quality Valve Series

 Threaded load check valve has the following advantages: 1, simple structure, manufacture and maintenance more convenient. 2, the working stroke is small, open and close a short time. 3, sealing, and the sealing surface friction force is small, longer life expectancy. Upload disadvantage threaded stop valve is as follows: 1, fluid resistance, the larger force required to open and closed. 2, does not apply with particles, viscosity, easy to medium coke. 3. Adjust better performance. Set only kind of threaded valve stem threads are divided by location external thread type, thread type. According to the flow of media points, straight-through, DC type and angle type. Cut-off valve according to the sealing form points, shut-off valve packing and bellows sealed stop valves.
