Main Feature:
The turning center of the butterfly plate is on the centerline of the valve body and the sealing face section of the butterfly plate. In closing, the ex-circle sealing face of the butterfly plate will extrude the valve seat made of synthetic rubber, generating elastic deformation on the seat to form an elastic force used as a sealing specific pressure so as to guarantee the tightness of the butterfly valve.
 Â
Â
Butterfly valve is widely used for cutting off or adjusting the fluid in the fields of petro-chem, industry, metallurgy, shipping, power, applying and draining water industry.

The automobile cooling system plays a particularly important role in automobile parts. The main job of the car cooling system is to dissipate heat into the air to prevent the engine from overheating, so that the engine can heat up as soon as possible and maintain a constant temperature.
When maintaining the car in winter, the maintenance of the car cooling system cannot be ignored, and car Antifreeze should be added to the water tank. Lidi's Heavy Duty Antifreeze can not only prevent freezing, but also prevent rust and scaling, inhibit foam generation, eliminate air resistance, and ensure the normal operation of water pumps.
Coolant And Antifreeze are both additives used in the car cooling system, but it is necessary to choose the appropriate additive according to the actual situation.
When cleaning the car cooling system, you can choose Radiator Flush for the cooling system, which can effectively remove the rust, scale and acidic substances in the entire cooling system.
The Radiator Stop Leak can cover the entire inner wall of the water tank, increasing the thickness of the water tank wall.
