The hard seal butterfly valve is a regulator with a simple structure, often used for media switch control in low-pressure pipelines. Its disc rotates within the body to open, close, or regulate flow.

The plunger valve features a design composed of a valve body, valve cover, valve stem, and plunger. Rotation of the hand wheel drives the plunger's reciprocating movement, completing the valve's opening and closing function.

The insulated pipeline valve maintains consistent fluid temperatures, reducing heat loss in pipelines. It prevents medium crystallization and solidification in petroleum, chemical, and pharmaceutical systems.
