It adopts an unbalanced valve core and is designed with features such as a cylindrical rear-guided type and the ability to quickly replace valve internal components. It is used for on-off or regulating control and is suitable for processes with wide requirements for pressure drop and temperature range. Single-seat regulating valve widely used in petroleum, natural gas, chemical, electric power, iron and steel industries such as water, air, liquid, gas, and viscous medium.
