According to the high-viscosity characteristics of asphalt, based on the existing valves， starting from practical situations, and absorbing domestic and overseas advanced thoughts, the Company has researched and developed BJ643H series pneumatic heat-preservation tee valve for conveying high-temperature asphalt, in order to greatly raise the production efficiency of China' s asphalt mixing equipment and asphalt system.

BJ643H series pneumatic heat -preservation tee valve adopts flange connection for its connection structure, and its valve body is made of cast steel. The valve core is made of aluminum alloy, and during utilization process, the valve core will be automatically adjusted and repaired according to the stainless steel sealing face of valve body, in order to extend the valve’s service life. Both the air cylinder and piston are designed and custom-made according to valve parameters, in order to ensure the valve’ S best opening and closing, and further extend the valve ’s service life. The upright post and valve rod are made of stainless steel, and they could ensure the normal use of the valve without being rusted in abominable environment. The spring installed on the piston rod not only guarantees the use of the valve under the pressure of 0.3Mpa~1 .0Mpa, but also exerts buffer function, protects valve core and piston, and meanwhile, when the air cylinder is lack of air, it could seal the outlet oil loop.

BJ643H series pneumatic heat- -preservation tee valve forms two seal cavities in the air cylinder by using the piston, achieves its own opening and closing through the pressure difference of the two seal cavities, and equips limit switches on the upper and lower covers of air cylinder, not only guaranteeing the displacement of valve core, but also realizing automatic control.
