On the basis of the traditional packing seal stop valve structure, our company refers to foreign advanced structures and through breakthrough technological improvements, we research and develop a new type of stop valve. The valve seat sealing surface is made into arc type and balanced plane sealing type. After grinding with special equipment, the valve seat seal is in contact with the soft sealing surface of the valve disc. Although the switch is frequently switched over a long period of time, it has been proven from theory and practice that the sealing surface will never be damaged or bitten, and a leak-free seal can be achieved for long-term use. Completely overcome the structural shortcomings of traditional stop valves.
Product features and applications:
, easy to operate, low cost, and long life.
, it has good tightness when closed, and its high value can ensure the minimum pressure drop when opened.
The stuffing type stop valve is suitable for cutting off condensate water, boiler water supply, boiler blowdown, hot water, cold water and heating systems. This valve cannot be used for hazardous media in the directive, fluids in group 1, such as flammable, explosive and toxic media.

/> ◎Design Features
The steel stop valve uses a combination of corrosion-inhibiting flexible graphite and reinforced graphite within a predetermined range to ensure effective sealing. When graphite packing is in the inner cavity with precise polishing accuracy and size, it can achieve the best sealing effect. When the stop valve is produced, the polished surface accuracy of the valve stem is higher than R, and the surface accuracy of the inner wall of the stuffing box is R . In addition, the straightness of the valve stem must also meet the same standard.
