Fire (signal) gate valve adopts the wedge gate structure of elastic seat sealing valve, and the deformation compensation effect is produced by the integral gluing of the gate to achieve good sealing effect. Stem nuts are in direct contact with the medium in the valve body. Rotary stem is used to drive the movement of the valve plate up and down through the nuts to realize the opening and closing of the gate valve. It can be used as a regulating and closing device in the system lines of construction, petroleum, chemical, food, textile, power ship, metallurgy and other industries.
The series valves have undergone rigorous sealing performance tests before they leave the factory.
